Description

The SN54LVCH245A octal bus transceiver is designed for 2.7-V to 3.6-V VCCoperation, and the SN74LVCH245A octal bus transceiver is designed for 1.65-V to 3.6-V VCCoperation. Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators in a mixed 3.3-V/5-V system environment.
