1. general description the 74vhc595-q100; 74vhct595-q100 are high -speed si-gate cmos devices and are pin compatible with low-power schottky ttl (l sttl). it is specified in compliance with jedec standard no. 7a. the 74vhc595-q100; 74vhct595-q100 are 8-stage serial shift registers with a storage register and 3-state outputs. the shift registers have separate clocks. data is shifted on the positive-going transiti ons of the shift register clock input (shcp). the data in each register is transferred to the storage register on a positive-going transition of the storage register clock input (stcp). if both clocks are connected together, the shift register is always one clock pulse ahead of the storage register. the shift register has a serial input (ds) and a serial standard output (q7s) for cascading. it is also provided with asynchronous reset (active low) for all 8 shift register stages. the storage register has 8 parallel 3-state bus driv er outputs. data in the storage register appears at the output wheneve r the output enable input (oe ) is low. this product has been qualified to the automotive electronics council (aec) standard q100 (grade 1) and is suitable for use in automotive applications. 2. features and benefits ? automotive product qualif ication in accordance with aec-q100 (grade 1) ? specified from ? 40 ? c to +85 ? c and from ? 40 ? c to +125 ? c ? balanced propagation delays ? all inputs have schmitt-trigger action ? inputs accept voltages higher than v cc ? input levels: ? the 74vhc595-q100 operates with cmos input level ? the 74vhct595-q100 operates with ttl input level ? esd protection: ? mil-std-883, method 3015 exceeds 2000 v ? hbm jesd22-a114f exceeds 2000 v ? mm jesd22-a115-a exceeds 200 v (c = 200 pf, r = 0 ? ) ? multiple package options 74vhc595-q100; 74vhct595-q100 8-bit serial-in/serial-out or parallel-out shift register with output latches rev. 1 ? 15 november 2013 product data sheet
