Revised September 2000 74F132 Quad 2-Input NAND Schmitt Trigger General Description The F132 contains four 2-input NAND gates 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 a greater noise margin than conventional NAND gates. ture. The Schmitt Trigger uses positive feedback to effectively speed-up slow input transitions, and provide different input threshold voltages for positive and negative-going transitions. This 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. Each circuit contains a 2-input Schmitt Trigger followed by level shifting circuitry and a standard FAST output struc- Ordering Code: Order Number Package Number Package Description 74F132SC M14A 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-120, 0.150 Narrow 74F132SJ M14D 14-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 74F132PC N14A 14-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide Devices also available in Tape and Reel.
