Product specification
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.

The logic equations for the outputs are: 1Y = 1E.(1I0.S1.S0+1I1.S1.S0+ +1I2.S1.S0+1I3.S1.S0) 2Y = 2E.(2I0.S1.S0+2I1.S1.S0+ +2I2.S1.S0+2I3.S1.S0) The "153" can be used to move data to a common output bus from a group of registers. The state of the select inputs would determine the particular register from which the data came. An alternative application is a function generator. The device can generate two functions or three variables. This is useful for implementing highly irregular random logic. The "153" is similar to the "253" but has standard outputs.

CPD is used to determine the dynamic power dissipation (PD in µW): PD = CPD × VCC2 × fi + (CL × VCC2 × fo) where: fi = input frequency in MHz fo = output frequency in MHz CL = output load capacitance in pF VCC = supply voltage in V (CL × VCC2 × fo) = sum of outputs 2. For HC the condition is VI = GND to VCC For HCT the condition is VI = GND to VCC - 1.5 V ORDERING INFORMATION See "74HC/HCT/HCU/HCMOS Logic Package Information". input capacitance power dissipation capacitance per multiplexer notes 1 and 2 CONDITIONS HC CL = 15 pF; VCC = 5 V 14 15 10 3.5 30 16 17 11 3.5 30 ns ns ns pF pF HCT UNIT
