DESCRIPTION
The 74HC/HCT594 are high-speed, Si-gate CMOS
devices, and are pin compatible with low power Schottky
TTL (LSTTL). They are specified in compliance with
JEDEC standard No. 7A.
The 74HC/HCT594 contain 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 (Q
purposes.
Both the shift and storage register clocks are positive-edge
triggered. If the user wishes to connect both clocks
together, the shift register will always be one count pulse
ahead of the storage register.
