1. general description the 74lv125 is a low-voltage si-gate cmos device that is pin and function compatible with 74hc125 and 74hct125. the 74lv125 provides four non-inverting buffer/line drivers with 3-state outputs. the 3-state outputs (ny) are controlled by the output enable input (n oe). a high at n oe causes the outputs to assume a high-impedance off-state. 2. features n wide operating voltage: 1.0 v to 5.5 v n optimized for low voltage applications: 1.0 v to 3.6 v n accepts ttl input levels between v cc = 2.7 v and v cc = 3.6 v n typical output ground bounce < 0.8 v at v cc = 3.3 v and t amb = 25 c n typical high-level output voltage (v oh ) undershoot: > 2 v at v cc = 3.3 v and t amb =25 c n esd protection: u hbm jesd22-a114e exceeds 2000 v u mm jesd22-a115-a exceeds 200 v n multiple package options n speci?ed from - 40 cto+85 c and from - 40 c to +125 c 3. ordering information 74lv125 quad buffer/line driver; 3-state rev. 03 7 april 2009 product data sheet table 1. ordering information type number package temperature range name description version 74lv125n - 40 c to +125 c dip14 plastic dual in-line package; 14 leads (300 mil) sot27-1 74lv125d - 40 c to +125 c so14 plastic small outline package; 14 leads; body width 3.9 mm sot108-1 74LV125DB - 40 c to +125 c ssop14 plastic shrink small outline package; 14 leads; body width 5.3 mm sot337-1 74lv125pw - 40 c to +125 c tssop14 plastic thin shrink small outline package; 14 leads; body width 4.4 mm sot402-1
