74AHCV244A

Octal buffer/line driver; 3-state

The 74AHCV244A is an 8-bit buffer/line driver with 3-state outputs and Schmitt trigger inputs. The device features two output enables (1OE and 2OE). A HIGH on nOE causes the associated outputs to assume a high-impedance OFF-state.

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

The data (nAn) and control (nOE) 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.
