74LVX3245QSC

74LVX3245QSC Description

The 74LVX3245QSC from onsemi is a bidirectional voltage level translator designed to facilitate seamless signal conversion between mixed-voltage systems. This 8-channel IC operates with VCCA (2.7V–3.6V) and VCCB (4.5V–5.5V), making it ideal for interfacing 3.3V logic with 5V systems. Packaged in a 24-QSOP tube, it features bidirectional data flow with direction control, ensuring robust signal integrity across voltage domains. Though marked Obsolete, it remains relevant for legacy designs due to its low-power CMOS technology and REACH/RoHS3 compliance, meeting stringent environmental standards.
