1. General description
The 74VHC126; 74VHCT126 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 No. 7-A.
The 74VHC126; 74VHCT126 provide 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 74VHC126; 74VHCT126 are identical to the 74VHC125; 74VHCT125 but have active
HIGH output enable inputs.
2. Features
