74AC14SJ

Overview

The onsemi 74AC14SJ is a hex inverter featuring Schmitt trigger inputs, manufactured using silicon gate CMOS technology. It operates within a supply voltage range of 2V to 6V and supports a maximum low-level output current of 24mA and a high-level output current of -24mA. The device provides six independent inverters in a 14-pin SOIC surface-mount package. It is designed for applications requiring noise immunity and signal conditioning, with an operating temperature range from -40°C to +85°C.

Feature Summary
