data sheet 26186.121 8-bit addressable dmos power driver the A6A259ka and A6A259klb combine a 3-to-8 line cmos decoder and accompanying data latches, control circuitry, and dmos outputs in a multi-functional power driver capable of storing single-line data in the addressable latches or use as a decoder or demuliplexer. driver applications include relays, solenoids, and other medium-current or high-voltage peripheral power loads. the cmos inputs and latches allow direct interfacing with micro- processor-based systems. use with ttl may require appropriate pull- up resistors to ensure an input logic high. four modes of operation are selectable with the clear and enable inputs. the addressed dmos output inverts the data input with all unaddressed outputs remaining in their previous states. all of the output drivers are disabled (the dmos sink drivers turned off) with the clear input low and the enable input high. the A6A259ka/klb dmos open-drain outputs are capable of sinking up to 500 ma. the A6A259ka is furnished in a 20-pin dual in-line plastic pack- age. the A6A259klb is furnished in a 24-lead wide-body, small- outline plastic batwing package (soic) with gull-wing leads for surface- mount applications. copper lead frames, reduced supply current re- quirements, and low on-state resistance allow both devices to sink 150 ma from all outputs continuously, to ambient temperatures over 85 c. features 50 v minimum output clamp voltage 350 ma output current (all outputs simultaneously) 1 ? typical r ds(on) internal short-circuit protection low power consumption replacements for tpic6a259n and tpic6a259dw 6a259 preliminary information (subject to change without notice) march 24, 2003 logic ground s 1 out 3 v dd power ground clear dwg. pp-050-4 out 2 power ground enable en power ground s 2 (msb) out 5 out 4 power ground out 0 out 1 s 0 (lsb) logic supply out 6 out 7 data decoder latches 13 14 15 16 17 19 12 18 20 11 1 2 3 8 9 4 5 6 7 10 absolute maximum ratings at t a = 25 c output voltage, v o ............................ 50 v output drain current, continuous, i o ...................... 350 ma * peak, i om ........................... 1100 ma*? peak, i om .................................... 2.0 a? single-pulse avalanche energy, e as ............................................. 75 mj logic supply voltage, v dd .............. 7.0 v input voltage range, v i ............................... -0.3 v to +7.0 v package power dissipation, p d ....................................... see graph operating temperature range, t a ............................. -40 c to +125 c storage temperature range, t s ............................. -55 c to +150 c *each output, all outputs on. ? pulse duration 100 s, duty cycle 2%. caution: these cmos devices have input static protection (class 3) but are still susceptible to dam- age if exposed to extremely high static electrical charges. always order by complete part number: part number package r ja r jc r jt A6A259ka 20-pin dip 55 c/w 25 c/w A6A259klb 24-lead soic 55 c/w 6 c/w A6A259ka (dip)

6a259 8-bit addressable dmos power driver www.allegromicro.com 5 functional description and input requirements four modes of operation are selectable by controlling the clear and enable inputs as shown above. in the addressable-latch mode, data at the data input is written into the addressed transparent latch. the addressed output inverts the data input with all other outputs remaining in their previous states. in the memory mode, all outputs remain in their previous states and are unaffected by the data or address (s n ) inputs. to prevent entering erroneus data in the latches, enable should be held high while the address lines are changing. in the demultiplexing/decoding mode, the addressed output inverts the data input and all other outputs are off. in the clear mode, all outputs are off and are unaffected by the data or address (s n ) inputs. given the appropriate inputs, when data is low for a given address, the output is off; when data is high, the output is on and can sink current. data input requirements data active time before enable (data set-up time), t su(d) .............................................. 20 ns data active time after enable (data hold time), t h(d) ................................................... 20 ns data pulse width, t w(d) ....................................................... 40 ns input logic high, v ih ................................................ 0.85v dd input logic low, v il ................................................. 0.15v dd 50% dwg. wp-037 enable data 50% w(d) t su(d) t h(d) t phl t plh t 50% addressed output dwg. wp-036 10% 90% f t r t enable data output switching time logic symbol g8 z9 9,0d 10,0r out 0 out 1 out 2 out 3 out 4 out 5 out 6 out 7 s 1 s 2 data enable dw g . fp-046-2 0 2 s 0 clear z10 8m 0/7 9,1d 10,1r 9,2d 10,2r 9,3d 10,3r 9,4d 10,4r 9,5d 10,5r 9,6d 10,6r 9,7d 10,7r
