INTEGRATED CIRCUITS 74F14 Hex inverter Schmitt trigger Product specification IC15 Data Handbook 1990 Nov 26 Philips Semiconductors Product specification Hex inverter Schmitt trigger 74F14 FEATURE PIN CONFIGURATION • Industrial temperature range available (–40°C to +85°C) TYPE TYPICAL PROPAGATION DELAY TYPICAL SUPPLY CURRENT (TOTAL) 5.0ns 18mA 74F14 DESCRIPTION D0 1 14 VCC Q0 2 13 D5 D1 3 12 Q5 Q1 4 11 D4 D2 5 10 Q4 Q2 6 9 D3 GND 7 8 Q3 The 74F14 contains six logic inverters which accept standard TTL input signals and provide standard TTL output levels. They are capable of transforming slowly changing input signals into sharply defined, jitter free output signals. In addition, they have greater noise margin than conventional inverters. Each circuit contains a Schmitt trigger followed by a Darlington level shifter and a phase splitter driving a TTL totem-pole output. The Schmitt trigger uses positive feedback to effectively speed-up slow input transitions, and provide different input threshold voltages for positive-going and negative-going input threshold (typically 800mV) is determined internally by resistor ratios and is insensitive to temperature and supply voltage variations.

For testing IOS, the use of high-speed test apparatus and/or sample-and-hold techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged shorting of a high output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any sequence of parameter tests, IOS tests should be performed last.
