Quad 2-Input Multiplexer

Features

Functional Description

• Function, pinout, and drive compatible with FCT and

The FCT157T is a quad two-input multiplexer that selects four

bits of data from two sources under the control of a common

data Select input (S). The Enable input (E) is Active LOW.

When (E) is HIGH, all of the outputs (Y) are forced LOW

regardless of all other input conditions.

F logic

• FCT-C speed at 4.3 ns max. (Com’l),

FCT-A speed at 5.0 ns max. (Com’l)

• Reduced V_OH(typically = 3.3V) versions of equivalent

FCT functions

• Edge-rate control circuitry for signiﬁcantly improved

noise characteristics

• Power-off disable feature

• Matched rise and fall times

• Fully compatible with TTL input and output logic levels

• ESD > 2000V

• Extended commercial range of −40˚C to +85˚C

Moving data from two groups of registers to four common

output buses is a common use of the FCT157T. The state of

the Select input determines the particular register from which

the data comes. It can also be used as a function generator.

The device is useful for implementing highly irregular logic by

generating any four of the sixteen different functions of two

variables with one variable common.

The FCT157T is a logic implementation of a four-pole,

two-position switch where the position of the switch is

determined by the logic levels supplied to the Select input.

• Sink current

64 mA (Com’l),

32 mA (Mil)

32 mA (Com’l),

Source current

The outputs are designed with a power-off disable feature to

allow for live insertion of boards.
