SN74AC14-Q1 SCAS915 – JUNE 2011 www.ti.com HEX SCHMITT-TRIGGER INVERTER Check for Samples: SN74AC14-Q1 FEATURES 1 • • • DESCRIPTION Qualified for Automotive Applications 2-V to 6-V VCC Operation Inputs Accept Voltages to 6 V This Schmitt-trigger device contain six independent inverters. They perform the Boolean function Y = A. Because of the Schmitt action, they have different input threshold levels for positive-going (VT+) and for negative-going (VT−) signals. PW PACKAGE (TOP VIEW) 1A 1Y 2A 2Y 3A 3Y GND 1 2 3 4 5 6 7 These circuits are temperature compensated and can be triggered from the slowest of input ramps and still give clean, jitter-free output signals. They also have a greater noise margin than conventional inverters.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. The input and output voltage ratings may be exceeded if the input and output current ratings are observed. The package thermal impedance is calculated in accordance with JESD 51-7.
