74AHC594PW,118

The 74AHC594PW is a 8-bit Si-gate CMOS Shift Register with output register. It is pin compatible with low-power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard No. 7-A. This non-inverting serial-in parallel-out shift register 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. A serial output (Q7S) is provided for cascading 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.

• Balanced propagation delays
• All inputs have Schmitt-trigger actions
• Inputs accept voltages higher than VCC
• Independent direct overriding clears on shift and storage registers
• Independent clocks for shift and storage registers
• Latch-up performance exceeds 100mA per JESD78 class II
• CMOS Input level
• Complies with JEDEC standard No. 7A
