MC74F14 PDF File ( Datasheet )

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

MC54, 74F148 8-LINE TO 3-LINE PRIORITY ENCODER The MC54, 74F148 provides three bits of binary coded output representing the position of the highest order active input, along with an output indicating the presence of any active input. It is easily expanded via input and output enables to provide priority encoding over many bits. Encodes Eight Data Lines in Priority Provides 3-Bit Binary Priority Code Input Enable Capability Signals When Data Present on Any Input Cascadable for Priority Enco
