74VHC125 74VHCT125 Quad buffer/line driver 3-state Rev. 3 8 April 2020 Product data sheet 1. General description The 74VHC125 74VHCT125 are high-speed Si-gate CMOS devices and are pin compatible with Low-power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard JESD7-A. The 74VHC125 74VHCT125 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. The 74VHC125 74VHCT125 are identical to the 74VHC126 74VHCT126 but have active LOW enable inputs. 2. Features and benefits Balanced propagation delays All inputs have a Schmitt-trigger action Inputs accepts voltages higher than V CC Input levels: The 74VHC125 operates with CMOS logic levels The 74VHCT125 operates with TTL logic levels ESD protection: HBM JESD22-A114E exceeds 2000 V MM JESD22-A115-A exceeds 200 V CDM JESD22-C101C exceeds 1000 V Multiple package options Specified from -40 C to +85 C and from -40 C to +125 C 3.
