74HC126; 74HCT126

Quad buffer/line driver; 3-state

The 74HC126; 74HCT126 is a quad buffer/line driver with 3-state outputs controlled by the output enable inputs (nOE). A LOW 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 V_CC.

特性

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)
Input levels:
- For 74HC126: CMOS levels
- For 74HCT126: TTL levels
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
