74LVX4245WMX

Translators, Level Shifters Overview

The onsemi 74LVX4245WMX is an 8-bit dual-supply translating transceiver with 3-STATE outputs, designed for mixed 3V/5V supply environments. It interfaces between a 5V bus (A Port) and a 3V bus (B Port). The device operates with VCCA from 4.5V to 5.5V and VCCB from 2.7V to 3.6V. It features bidirectional data flow controlled by Transmit/Receive inputs and Output Enable. Outputs source/sink 24 mA at the 5V bus and 12 mA at the 3V bus. Propagation delay ranges from 1.0 ns to 10.0 ns depending on direction and load. It is housed in a 24-Lead SOIC package.
