1. general description the 74hc164-q100; 74hct164-q100 is an 8-bit serial-in/parallel-out shift register. the device features two serial data inputs (dsa and dsb), eight parallel data outputs (q0 to q7). data is entered serially through dsa or dsb and either input can be used as an active high enable for data entry through the other input. data is shifted on the low-to-high transitions of the clock (cp) in put. a low on the master reset input (mr) clears the register and forces all outputs low, independently of other inputs. inputs include clamp diodes that enable the use of cu rrent limiting resistors to interface inputs to voltages in excess of v cc . 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 ? input levels: ? for 74hc164-q100: cmos level ? for 74hct164-q100: ttl level ? gated serial data inputs ? asynchronous master reset ? complies with jedec standard no. 7a ? 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 74hc164-q100; 74hct164-q100 8-bit serial-in, parallel-out shift register rev. 1 ? 16 august 2013 product data sheet
