74ABT126D buffer equivalent, quad buffer.
* 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.
using IOFF. The IOFF circuitry disables the output, preventing the potentially damaging backflow current through the dev.
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 usin.
