Description

• Common Select Inputs

• Separate Enable Inputs

• Buffered inputs and Outputs

• Fanout (Over Temperature Range)

The Harris CD74HC157, CD74HCT157, CD74HC158 and

CD74HCT158 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-

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

output busses 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.
