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
