Features

Description

• Common Select Inputs

• Separate Enable Inputs

• Buffered inputs and Outputs

• Fanout (Over Temperature Range)

The ’HC157, ’HCT157, ’HC158, and ’HCT158 are quad 2-

input multiplexers which select four bits of data from two

sources under the control of a common Select input (S). The

Enable input (E) is active Low. When (E) is High, all of the

outputs in the 158, the inverting type, (1Y-4Y) are forced

High and in the 157, the non-inverting type, all of the outputs

- Standard Outputs. . . . . . . . . . . . . . . 10 LSTTL Loads

(1Y-4Y) are forced Low, regardless of all other input

- Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads conditions.

• Wide Operating Temperature Range . . . -55 C to 125 C Moving data from two groups of registers to four common

output buses is a common use of these devices. The state of

the Select input determines the particular register from

which the data comes. They can also be used as function

generators.

• Balanced Propagation Delay and Transition Times

• Signiﬁcant Power Reduction Compared to LSTTL

Logic ICs

• HC Types
