SN74HC14APW Description
The SN74HC14APW from Texas Instruments is a high-performance hex Schmitt-trigger inverter integrated circuit (IC) housed in a 14-pin TSSOP surface-mount package. Part of the 74HC series, this device operates over a 2V to 6V supply voltage range, making it compatible with a wide variety of digital systems. It features six independent inverters, each with Schmitt-trigger inputs for improved noise immunity and signal conditioning. With a maximum propagation delay of 19ns at 6V and 50pF load, it ensures reliable high-speed logic inversion. The IC is designed for low power consumption, with a quiescent current of just 2µA (max), making it suitable for battery-powered applications.
