74AHC126 74AHCT126 Quad buffer/line driver 3-state Rev. 5 28 April 2020 Product data sheet 1. General description The 74AHC126 74AHCT126 is a quad buffer/line driver with 3-state outputs controlled by the output enable inputs (nOE). A LOW on nOE causes the outputs to assume a high-impedance OFF-state. Inputs are overvoltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments. 2. Features Balanced propagation delays All inputs have Schmitt-trigger action Inputs accept voltages higher than V CC Input levels: For 74AHC126: CMOS level For 74AHCT126: TTL level 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.
