1/16 february 2005 8 constant current output channels adjustable output current through external resistor serial data in/parallel data out serial out change state on the failing edges of clock output current: 15-120 ma 25 mhz clock freq. available in high thermal tssop exposed pad efficiency package description the stp08c596 is a monolithic, medium-voltage, low current power 8-bit shift register designed for led panel display. the stp08c596 contains a 8-bit serial-in, parallel-out shift register that feeds a 8-bitd-type storage register. in the output stage, sixteen regulated current sources were designed to provide 15-120ma constant current to drive the leds. compared with the stpic6c595, the device provides great flexibility and improved performance in led panel system design. trough an external resistor, users may adjust the stp08c596 output current, controlling in this way the light intensity of leds. the stp08c596 guarantees 16v output driving capability, allowing users to connect more leds in series. the high clock frequency, 25 mhz, also satisfies the system requirement of high volume data transmission. table 1: order codes part number temp. range package comments stp08c596b1 -40c to 125c dip-16 25 part per tube stp08c596m -40c to 125c so-16 (tube) 50 parts per tube stp08c596mtr -40c to 125c so-16 (tape & reel) 1000 parts per reel STP08C596TTR -40c to 125c tssop16 (tape & reel) 2500 parts per reel stp08c596 8-bit constant current led sink driver so-16 dip-16 tssop16 rev. 7
