74LV125 Quad buffer/line driver 3-state Rev. 03 7 April 2009 Product data sheet 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 (nOE). A HIGH at nOE 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 = 2.7 V and V = 3.6 V CC CC n Typical output ground bounce < 0.8 V at V = 3.3 V and T = 25 C CC amb n Typical HIGH-level output voltage (V ) undershoot: > 2 V at V = 3.3 V and OH CC T =25 C amb n ESD protection: u HBM JESD22-A114E exceeds 2000 V u MM JESD22-A115-A exceeds 200 V n Multiple package options n Specied from - 40 Cto+85 C and from - 40 C to +125 C 3.
