74VHC594 Datasheet (STMicroelectronics)

74VHC594, 8-BIT SHIFT REGISTER

The 74VHC594 is an high speed CMOS 8-BIT SHIFT REGISTERS fabricated with sub-micron silicon gate C2MOS technology.

This device contains an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register.

Separate clocks and direct overriding clear (SCLR, RCLR) are provided f
