SN54/74LS13 SCHMITT TRIGGERS SN54/74LS14 DUAL GATE/HEX INVERTER The SN54LS / 74LS13 and SN54LS / 74LS14 contain logic gates / inverters which accept standard TTL input signals and provide standard TTL output levels. They are capable of transforming slowly changing input signals into SCHMITT TRIGGERS sharply defined, jitter-free output signals. Additionally, they have greater noise DUAL GATE/ HEX INVERTER margin than conventional inverters. Each circuit contains a Schmitt trigger followed by a Darlington level shifter LOW POWER SCHOTTKY 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 J SUFFIX essentially insensitive to temperature and supply voltage variations.
