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 VCC.

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

 Multiple package options

 Specified from 40 C to +85 C and from 40 C to +125 C

3. Applications

 Data selectors

 Data multiplexers
