M74HC14YRM13TR

M74HC14YRM13TR Description

The M74HC14YRM13TR from STMicroelectronics is a high-performance hex Schmitt-trigger inverter IC designed for automotive-grade applications. Part of the 74HC series, this device integrates six independent Schmitt-trigger inverters in a single 14-pin SO package, making it ideal for noise filtering, signal conditioning, and waveform shaping. Operating within a 2V to 6V supply range, it ensures robust performance in mixed-voltage environments while consuming minimal quiescent current (1 µA max). With a maximum propagation delay of 21ns at 6V and 50pF load, it delivers high-speed switching suitable for timing-critical applications.
