Product Summary
The SN74LVCH244APWR is a quadruple 2-input positive-nand gate. It is designed for 1.65-V to 3.6-V VCC operation. Inputs can be driven from either 3.3-V or 5-V devices. This feature of the SN74LVCH244APWR allows the use of these devices as translators in a mixed 3.3-V/5-V system environment.
