74AHC9541A

Octal buffer/line driver; 3-state

The 74AHC9541A is an 8-bit buffer/line driver with 3-state outputs and Schmitt trigger inputs. The device features an output enable input (OE) and select input (S). A HIGH on OE causes the associated outputs to assume a high-impedance OFF-state. A LOW on the select input S causes the buffer/line driver to act as an inverter.

Inputs are overvoltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments.

The data (An), select (S) and output enable (OE) inputs include Schmitt trigger inputs, capable of transforming slowly changing input signals into sharply defined, jitter-free output signals.

This device is fully specified for partial Power-down applications using IOFF. The IOFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down.
