The 74F132 is an integrated circuit manufactured by Fairchild Semiconductor Corporation that has four 2-input NAND gates. It can accept standard TTL input signals and provide standard TTL output levels. It is faster than conventional NAND gates and has a greater noise margin. Each circuit contains a 2-input Schmitt trigger, followed by level shifting circuitry and a standard FAST® output structure. The Schmitt trigger uses positive feedback to effectively speed up slow input transitions and provide different input threshold voltages for positive and negative transitions. The hysteresis between the positive-going and negative-going input threshold (typically 800 mV) is determined by resistor ratios and is essentially insensitive to temperature and supply voltage variations.
This document is a technical datasheet for the Fairchild Semiconductor 74F132, a quad 2-input NAND gate with Schmitt Trigger functionality. The device accepts standard TTL input signals and provides standard TTL output levels while transforming slowly changing inputs into sharply defined outputs.
The datasheet includes absolute maximum ratings, recommended operating conditions, DC and AC electrical characteristics, logic symbol connection diagrams, unit loading/fan-out function tables, and physical dimensions for three available package types: SOIC (M14A), SOP (M14D), and PDIP (N14A).
| Positive-going Threshold Voltage (V_T+) | 2.0 V to 5.0 V |
|---|---|
| Negative-going Threshold Voltage (V_T-) | 0.7 V to 5.0 V |
| Hysteresis Voltage (V_HY) | 0.4 V to 5.0 V |
| Supply Voltage Range | +4.5V to +5.5V |
The hysteresis voltage typically ranges from 0.4V to 5.0V, determined by resistor ratios.
Yes, it accepts standard TTL input signals and provides standard TTL output levels.
