74F253Dual 4-input multiplexer (3-State)

FEA TURES

•3-State outputs for bus interface and multiplex expansion

•Common select inputs

•Separate Output Enable Inputs

DESCRIPTION

The 74F253 has two identical 4-input multiplexers with 3-State
outputs which select two bits from four sources selected by common
Select inputs (S0, S1). When the individual Output Enable (OE

b) inputs of the 4-input multiplexers are High, the outputs are

OE
forced to a high impedance (Hi-Z) state.

The 74F253 is the logic implementation of a 2-pole, 4-position
switch; the position of the switch being determined by the logic
levels supplied to the two common Select inputs.

To avoid exceeding the maximum current ratings when the outputs
of the 3-State devices are tied together, all but one device must be
in the high-impedance state. Therefore, only one Output Enable
must be active at a time.

Definitions

Short-form specification — The data in a short-form specification is extracted from a full data sheet with the same type number and title. For

detailed information see the relevant data sheet or data handbook.
Limiting values definition — Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one

or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or
at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended
periods may affect device reliability.
