74HC3G34; 74HCT3G34
Triple buffer gate
The 74HC3G34; 74HCT3G34 is a triple buffer. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
Features and benefits
Wide supply voltage range from 2.0 V to 6.0 V
Input levels:
For 74HC3G34: CMOS level
For 74HCT3G34: 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: 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 -40 °C to +125 °C
