1. general description the 74ahc594; 74ahct594 is a high-speed si-gate cmos device and is pin compatible with low-power schottky ttl (lsttl). it is speci?ed in compliance with jedec standard no. 7a. the 74ahc594; 74ahct594 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. 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. 2. features n wide supply voltage range from 2.0 v to 5.5 v n 8-bit serial-in, parallel-out shift register with storage n independent direct overriding clears on shift and storage registers n independent clocks for shift and storage registers n latch-up performance exceeds 100 ma per jesd 78 class ii n input levels: u cmos levels: 74ahc594 only u ttl levels: 74ahct594 only n esd protection: u hbm jesd22-a114-c exceeds 2000 v u mm jesd22-a115-a exceeds 200 v u cdm jesd22-c101-c exceeds 1000 v n speci?ed from - 40 c to +85 c and from - 40 c to +125 c 3. applications n serial-to parallel data conversion n remote control holding register 74ahc594; 74ahct594 8-bit shift register with output register rev. 01 4 july 2006 product data sheet
