DESCRIPTION
The 74F157A is a high speed Quad 2-Input Multiplexer which
selects 4 bits of data from one of two sources under the control of a
common Select input (S). The Enable input (E) is active when Low.
When E is High, all of the outputs (Yn) are forced Low regardless of
all other input conditions.
Moving data from two registers to a common output bus is a
common use of the 74F157A. The state of the Select input
determines the particular register from which the data comes.
The device is the logic implementation of a 4-pole, 2-position switch
where the position of the switch is determined by the logic levels
supplied to the Select input.
The 74F158A is similar, but has inverting outputs (Yn).

NOTES:
1. For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions for the applicable type.
2. All typical values are at V
CC
= 5V, T
amb
= 25
C.
3. Not more than one output should be shorted at a time. For testing I
OS
, the use of high-speed test apparatus and/or sample-and-hold
techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged shorting
of a High output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any
sequence of parameter tests, I
OS
tests should be performed last.
4. I
CC
is measured with 4.5V applied to all inputs and all outputs open.
