74ALVC541

Octal buffer/line driver; 3-state

The 74ALVC541 is an 8-bit buffer/line driver with 3-state outputs. The device features two output enables (OE1 and OE2). A HIGH on OEn causes the associated outputs to assume a high-impedance OFF-state.

Schmitt trigger action on all inputs makes the device tolerant of slow rise and fall times.

This device is fully specified for partial power down applications using I_OFF. The I_OFF circuitry disables the output, preventing the potentially damaging backflow current through the device when it is powered down.

Features and benefits

Wide supply voltage range from 1.65 V to 3.6 V
CMOS low power dissipation
Overvoltage tolerant inputs to 3.6 V
Direct interface with TTL levels
I_OFF circuitry provides partial Power-down mode operation
Latch-up performance exceeds 250 mA per JESD78 Class II.A
Complies with JEDEC standard:
- JESD8-7 (1.65 V to 1.95 V )
- JESD8-5 (2.3 V to 2.5 V)
- JESD8C/JESD36 (2.7 V to 3.6 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
Multiple package options
Specified from -40 °C to +85 °C and from -40 °C to +125 °C
