onsemi MC74VHC04/MC74VHCT04A CMOS Hex Inverters

onsemi MC74VHC04/MC74VHCT04A Complementary Metal-Oxide-Semiconductor (CMOS) Hex Inverters are high-speed CMOS quad inverters fabricated with silicon gate CMOS technology. These onsemi inverters achieve high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation. The MC74VHC04 inputs are compatible with standard CMOS levels, while the MC74VHCT04A inputs are compatible with TTL levels. These devices can be used as a level converter for interfacing 3.3V to 5.0V, thanks to full 5.0V CMOS level output swings.

The MC74VHC04 and MC74VHCT04A internal circuits are composed of three stages, including a buffer output that provides high noise immunity and a stable output. The input structures tolerate voltages up to 5.5V, allowing the interface of 5V systems to 3V systems. The MC74VHCT04A output structures provide protection when VCC = 0V. These output structures help prevent device destruction caused by supply voltage input/output mismatches, battery backups, hot insertion, and more.
