Dual 4-input multiplexer
FEATURES Non-inverting output Separate enable for each output Common select inputs See ‘253” for 3-state version Permits multiplexing from n lines to 1 line Enable line provided for cascading (n lines to 1 line) Output capability: standard ICC category: MSI GENERAL DESCRIPTION The 74HC/HCT153 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT153 have two identical 4-input multiplexers which select two bits of data from up to four sources selected by common data select inputs (S0, S1). The two 4-input multiplexer circuits have individual active LOW output enable inputs (1E, 2E) which can be used to strobe the outputs independently. The outputs (1Y, 2Y) are forced LOW when the corresponding output enable inputs are HIGH. The “153” is the logic implementation of a 2-pole, 4-position switch, where the position of the switch is determined by the logic levels applied to S0 and S1.
