74HC594; 74HCT594 8-bit shift register with output register Rev. 03 — 20 December 2006 Product data sheet 1. General description The 74HC594; 74HCT594 is a high-speed Si-gate CMOS device and is pin compatible with Low-Power Schottky TTL (LSTTL). The 74HC594; 74HCT594 is an 8-bit, non-inverting, serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. Separate clocks (SHCP and STCP) and direct overriding clears (SHR and STR) are provided on both the shift and storage registers.
