MC74LVXC3245DTG Description

The MC74LVXC3245DTG from onsemi is a bidirectional voltage level translator designed for interfacing between mixed-voltage systems. Housed in a 24-pin TSSOP package, this IC facilitates seamless communication between circuits operating at 2.3V–3.6V (VCCA) and 3V–5.5V (VCCB). As part of the 74LVXC series, it ensures robust signal integrity while minimizing power consumption, making it ideal for portable and battery-powered applications. Though marked Obsolete, it remains relevant for legacy designs requiring reliable voltage translation with 8 bidirectional channels per circuit.
