STPIC6C595

STPIC6C595 Power logic 8-bit shift register Features ■ Low RDS(on): 4 Ω typ ■ 30 mJ avalanche energy ■ Eight 100 mA DMOS outputs ■ 250 mA current limit capability ■ 33 V output clamp voltage ■ Device are cascadable ■ Low power consumption Description This STPIC6C595 is a monolithic, mediumvoltage, low current power 8-bit shift register designed for use in systems that require relatively moderate load power such as LEDs. The device contains a built-in voltage clamp on the outputs for inductive transient protection. Power driver applications include relays, solenoids, and other low-current or medium-voltage loads. The device contains an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. Data transfers through both the shift and storage register clock (SRCK) and the register clock (RCK), respectively. The device transfers data out the serial output (SER OUT) port on the rising edge of SRCK. The storage register transfers data to the output buffer when shift register clear (CLR) is high. When CLR is low, the input shift register is cleared. When output enable (G) is held high, all data in the output buffer is held low and all drain output are off. When G is held low, data from the storage register is transparent to the output buffer. SO-16 TSSOP16 When data in the output buffers is low, the DMOS transistor outputs are off. When data is high, the DMOS transistor outputs have sink-current capability. The SER OUT allows for cascading of the...
