74VHC126; 74VHCT126
Quad buffer/line driver; 3-state
Rev. 01 — 13 August 2009
Product data sheet
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
I Balanced propagation delays
I All inputs have Schmitt-trigger action
I Inputs accept voltages higher than VCC
I Input levels:
N The 74VHC126 operates with CMOS input level
N The 74VHCT126 operates with TTL input level
I ESD protection:
N HBM JESD22-A114E exceeds 2000 V
N MM JESD22-A115-A exceeds 200 V
N CDM JESD22-C101C exceeds 1000 V
I Multiple package options
I Specified from −40 °C to +85 °C and from −40 °C to +125 °C
