74HC253; 74HCT253
Dual 4-input multiplexer; 3-state
Rev. 6 — 1 February 2016
Product data sheet
1. General description
The 74HC253; 74HCT253 is a dual 4-bit multiplexer, each with four binary inputs (nI0 to
nI3), an output enable input (nOE) and shared select inputs (S0 and S1). One of the four
binary inputs is selected by the select inputs and routed to the output nY. A HIGH on nOE
causes the outputs to assume a high-impedance OFF-state. Inputs include clamp diodes.
This enables the use of current limiting resistors to interface inputs to voltages in excess
of V
CC
.
2. Features and benefits
Non-inverting data path
3-state outputs interface directly with system bus
Complies with JEDEC standard no. 7A
Common select inputs
Separate output enable inputs
Input levels:
For 74HC253: CMOS level
For 74HCT253: TTL level
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-A exceeds 200 V
