74LVX4245MTR

Translators, Level Shifters Overview

The STMicroelectronics 74LVX4245MTR is an octal dual-supply bus transceiver utilizing C2MOS technology. It facilitates asynchronous communication between a 5V bus and a 3.3V bus in mixed-voltage systems. The device features three-state outputs controlled by the DIR input for transmission direction and the G input for enabling or disabling the buses. Operating voltage ranges are 4.5V to 5.5V for VCCA and 2.7V to 3.6V for VCCB, with data retention at 1.2V.
