the tpic6c596 is a monolithic medium-voltage low-current power 8-bit shift register designed for use systems that require relatively moderate load power such as leds. the device conta s a built- voltage clamp on the outputs for ductive transient protection. power driver applications clude relays solenoids and other low-current or medium-voltage loads. this device conta s an 8-bit serial- parallel-out shift register that feeds an 8-bit d-type storage register. data transfers through both the shift and storage registers on the ris g edge of the shift register clock (srck) and the register clock (rck) respectively. the storage register transfers data to the output buffer when shift register clear (clr)\ is high.
