SN74LV14APW

SN74LV14APW Description

The SN74LV14APW from Texas Instruments is a hex Schmitt-trigger inverter housed in a 14-pin TSSOP package, designed for surface-mount applications. Operating within a 2V to 5.5V supply range, it features six independent inverters with Schmitt-trigger inputs, ensuring robust noise immunity and signal conditioning. With a maximum propagation delay of 10.6ns at 5V and 50pF load, it delivers high-speed performance suitable for digital logic applications. The device supports 12mA output current (both high and low) and consumes a quiescent current of just 20µA (max), making it energy-efficient.
