74ABT126
Quad buffer; 3-state
Rev. 6 — 8 October 2020
Product data sheet
1. General description
The 74ABT126 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. This
device is fully specified for partial power down applications using IOFF. The IOFF circuitry disables
the output, preventing the potentially damaging backflow current through the device when it is
powered down.
2. Features and benefits
Supply voltage range from 4.5 V to 5.5 V
BiCMOS high speed and output drive
Direct interface with TTL levels
Power-up 3-state
IOFF circuitry provides partial Power-down mode operation
Quad bus interface
3-state buffers
Live insertion and extraction permitted
Output capability: +64 mA and -32 mA
Inputs are disabled during 3-state mode
Latch-up protection:
JESD78: exceeds 500 mA
ESD protection:
MIL STD 883 method 3015: exceeds 2000 V
MM JESD22-A115-A exceeds 200 V
