may 2006 rev 4 1/26 26 stp16cp596 low voltage 16-bit, constant current led sink driver features low voltage power supply down to 3v 16 constant current output channels adjustable output current through external resistor serial data in/parallel data out serial out changes stat e on the falling edges of clock 3.3v micro driver-able output current: 3-50 ma 25mhz clock frequency available in high thermal efficiency tssop exposed pad description the stp16cp596 is a monolithic, low voltage, low current power 16-bit shift register designed for led panel displays. the stp16cp596 contains a 16-bit serial-in, parallel- out shift register that feeds a 16-bit, d-type storage register. in the output stage, sixteen regulated current sources were designed to provide 3-50ma constant current to drive the leds. compared with the stpic6c595, the device provides great flexibility and improved performance in led panel system design. users can adjust the stp16cp596 output current with an external resistor, controlling the leds' light intensity. the stp16cp596 guarantees a 16v output driving capability, allowing users to connect more leds in series. the high clock frequency (25mhz) also satisfies the high volume data transmission system requirement. the 3.3v voltage supply is useful for applications that interface any microprocessor from 3.3v. compared with a standard tssop package, the tssop exposed pad increases heat dissipation capability by a factor of 2:5. dip-24 so-24 tssop24 tssop24 (exposed pad) www.st.com order codes part number package packaging stp16cp596b1r dip-24 15 parts per tube stp16cp596m so-24 (tube) 40 parts per tube stp16cp596mtr so-24 (tape & reel) 1000 parts per reel stp16cp596ttr tssop24 (tape & reel) 2500 parts per reel STP16CP596XTTR tssop24 exposed-pad (tape & reel) 2500 parts per reel obsolete product(s) - obsolete product(s)
