74AHCT126D

Quad buffer/line driver; 3-state

The 74AHC126; 74AHCT126 is a high-speed Si-gate CMOS device and is pin compatible with Low-power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard No. 7-A.

The 74AHC126; 74AHCT126 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 LOW-level at pin nOE causes the outputs to assume a high-impedance OFF-state.

The 74AHC126; 74AHCT126 is identical to the 74AHC125; 74AHCT125 but has active HIGH output enable inputs.
