74LS132

SN74LS132 Quad 2-Input Schmitt Trigger NAND Gate The SN74LS132 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. Additionally, they have greater noise margin than conventional NAND Gates. Each circuit contains a 2-input 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 and negative-going transitions. This hysteresis between the positive-going and negative-going input thresholds (typically 800 mV) is determined internally by resistor ratios and is essentially insensitive to temperature and supply voltage variations. As long as one input remains at a more positive voltage than VT+ (MAX), the gate will respond to the transitions of the other input as shown in Figure 1. http://onsemi.com LOW POWER SCHOTTKY 14 1 LOGIC AND CONNECTION DIAGRAM DIP (TOP VIEW) VCC 14 13 12 11 10 9 8 PLASTIC N SUFFIX CASE 646 14 1 1 2 3 4 5 6 7 GND SOIC D SUFFIX CASE 751A GUARANTEED OPERATING RANGES Symbol VCC TA IOH IOL Parameter Supply Voltage Operating Ambient Temperature Range Output Current – High Output Current – Low Min 4.75 0 Typ 5.0 25 Max 5.25 70 – 0.4 8.0 Unit V °C mA mA ORDERING INFORMATION Device ...
