Product Summary

The 74HC594D is a high-speed, Si-gate CMOS device, and is pin compatible with low power Schottky TTL (LSTTL). The device is specified in compliance with JEDEC standard No. 7A. The 74HC594D contains an 8-bit, non-inverting, serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. Separate clocks and direct overriding clears are provided on both the shift and storage registers. A serial output (Q7’) is provided for cascading purposes. The applications of the 74HC594D include Serial-to parallel data conversion, Remote control holding register.
