Product Introduction
The 74HC257; 74HCT257 is a quad 2-input multiplexer with 3-state outputs. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
Features
- Wide supply voltage range from 2.0 V to 6.0 V
- 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)
- Non-inverting data path
- 3-state outputs interface directly with system bus
- Input levels:
- For 74HC257: CMOS level
- For 74HCT257: TTL level
- ESD protection:
- HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V
- CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V
- Specified from -40 °C to +85 °C and from -40 °C to +125 °C
Applications
- System bus interface
- Logic level translation
- Data selection and multiplexing
- 3-state output control
