1. general description the 74lv165-q100 is an 8-bit parallel-load or serial-in shift register with complementary serial outputs (q7 and q7 ) available from the last stage. when the parallel-load input (pl ) is low, parallel data from the inputs d0 to d7 are loaded into the register asynchronously. when input pl is high, data enters the register seria lly at the input ds. it shifts one place to the right (q0 ?? q1 ?? q2, etc.) with each positive-going clock transition. this feature allows parallel-to-serial converter expansion by tying the ou tput q7 to the input ds of the succeeding stage. the clock input is a gate-or structure which allows one input to be used as an active low clock enable input (ce ) input. the pin assignment for the inputs cp and ce is arbitrary and can be reversed for layout co nvenience. the low-to-high transition of the input ce should only take place while cp high fo r predictable operation. either the cp or the ce should be high before the low-to-high transition of pl to prevent shifting the data when pl is activated. 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 ? wide supply voltage range from 1.0 v to 5.5 v ? synchronous parallel-to-serial applications ? optimized for low voltage applications: 1.0 v to 3.6 v ? synchronous serial input for easy expansion ? latch-up performance exceeds 250 ma ? 5.5 v tolerant inputs/outputs ? direct interface with ttl levels (2.7 v to 3.6 v) ? power-down mode ? complies with jedec standards: ? jesd8-5 (2.3 v to 2.7 v) ? jesd8b/jesd36 (2.7 v to 3.6 v) ? jesd8-1a (4.5 v to 5.5 v) ? esd protection: ? mil-std-833, method 3015 exceeds 2000 v ? hbm jesd22-a114f exceeds 2000 v ? mm jesd22-a115-a exceeds 200 v (c = 200 pf, r = 0 ? ) 74lv165-q100 8-bit parallel-in/seria l-out shift register rev. 2 ? 24 february 2014 product data sheet
