74HC253
Overview
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.
- 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
