74ABT126
Quad buffer; 3-state
Rev. 04 — 17 February 2005
Product data sheet
1. General description
The 74ABT126 high-performance BiCMOS device combines low static and dynamic
power dissipation with high speed and high output drive.
The 74ABT126 device is a quad buffer that is ideal for driving bus lines. The device
features four output enable inputs (nOE each controlling one of the 3-state outputs (nY).
2. Features
s Quad bus interface
s 3-state buffers
s Live insertion and extraction permitted
s Output capability: +64 mA and −32 mA
s Inputs are disabled during 3-state mode
s Power-up 3-state
s Latch-up protection:
x JESD78: exceeds 500 mA
s ESD protection:
x MIL STD 883 method 3015: exceeds 2000 V
x Machine model: exceeds 200 V
