The device contains a built-in voltage clamp on the outputs for inductive transient protection. Power driver applications include relays, solenoids, and other medium-current or high-voltage loads. G9 RCK 12 8 SRCLR 13 SRCK EN3 C2 SRG8 R C1 This 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 registers on the rising 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 (SRCLR) is high. When SRCLR is low, all registers in the device are cleared. When output enable (G) is held high, all data in the output buf...
