74AHC2G126GD,125

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHC2G126GD,125 is a dual buffer and line driver featuring three-state outputs controlled by active-high output enable inputs (nOE). It operates within a supply voltage range of 2.0 V to 5.5 V and utilizes an 8-XSON package with dimensions of 2x3 mm. The device provides symmetrical output impedance and balanced propagation delays. Inputs are overvoltage tolerant up to 5.5 V, allowing use in mixed-voltage environments. It is specified for operation from -40 °C to +125 °C.
