- Inputs include clamp diodes, enabling the use of current limiting resistors to interface inputs to voltages in excess of VCC.
- 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) and JESD7A (2.0 V to 6.0 V).
- Input levels: CMOS levels for 74HC126-Q100 and TTL levels for 74HCT126-Q100.
- HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V and CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V.
