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

• Common select inputs

• Separate output enable inputs

• Wide supply voltage range from 2.0 V to 6.0 V

• Input levels:

• For 74HC253: CMOS level

• For 74HCT253: TTL level

• CMOS low power dissipation

• High noise immunity

• Latch-up performance exceeds 100 mA per JESD 78 Class II Level B

• Complies with JEDEC standards

• JESD8C (2.7 V to 3.6 V)

• JESD7A (2.0 V to 6.0 V)

• ESD protection:

• HBM JESD22-A114F exceeds 2 kV

• 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
