MC54F13 SCHMITT TRIGGERS DUAL 4-INPUT NAND/HEX INVERTERS

SCHMITT TRIGGERS DUAL 4-INPUT NAND/HEX INVERTERS The MC54/74F13 and MC54/74F14 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 sharply defined, jitter-free output signals. Additionally, 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.
