INTEGRATED CIRCUITS DATA SHEET 74HC14; 74HCT14 Hex inverting Schmitt trigger Product specification Supersedes data of 1997 Aug 26 2003 Oct 30 Philips Semiconductors Product specification Hex inverting Schmitt trigger FEATURES • Applications: – Wave and pulse shapers – Astable multivibrators – Monostable multivibrators. • Complies with JEDEC standard no. 7A • ESD protection: HBM EIA/JESD22-A114-A exceeds 2000 V MM EIA/JESD22-A115-A exceeds 200 V. • Specified from −40 to +85 °C and −40 to +125 °C. QUICK REFERENCE DATA GND = 0 V; Tamb = 25 °C; tr = tf = 6 ns DESCRIPTION 74HC14; 74HCT14 The 74HC14 and 74HCT14 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. The 74HC14 and 74HCT14 provide six inverting buffers with Schmitt-trigger action. They are capable of transforming slowly changing input signals into sharply defined, jitter-free output signals. TYPICAL SYMBOL tPHL/tPLH CI CPD Notes 1. CPD is used to determine the dynamic power dissipation (PD in µW): PD = CPD × VCC2 × fi × N + Σ(CL × VCC2 × fo) where: fi = input frequency in MHz; fo = output frequency in MHz; CL = output load capacitance in pF; VCC = supply voltage in Volts; N = total load switching outputs; Σ(CL × VCC2 × fo) = sum of the outputs. 2. For type 74HC14 the condition is VI = GND to VCC. For type 74HCT14 the condition is VI = GND to VCC − 1.5 V.

This can be calculated using the following formula: Pad = fi × (tr × ICC(AV) + tf × ICC(AV)) × VCC. Where: Pad = additional power dissipation (µW); fi = input frequency (MHz); tr = input rise time (µs); 10% to 90%; tf = input fall time (µs); 10% to 90%; ICC(AV) = average additional supply current (µA). ICC(AV) differs with positive or negative input transitions, as shown in Figs 16 and 17. For 74HC/HCT14 used in a relaxation oscillator circuit, see Fig.18.

Please consult the most recently issued data sheet before initiating or completing a design. 2. The product status of the device(s) described in this data sheet may have changed since this data sheet was published. The latest information is available on the Internet at URL http://www.semiconductors.philips.com. 3. For data sheets describing multiple type numbers, the highest-level product status determines the data sheet status. DEFINITIONS Short-form specification  The data in a short-form specification is extracted from a full data sheet with the same type number and title. For detailed information see the relevant data sheet or data handbook. Limiting values definition  Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 60134). Stress above one or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended periods may affect device reliability.
