IDT74ALVC125
0.5 MICRON CMOS Technology
ESD > 2000V per MIL-STD-883, Method 3015;
> 200V using machine model (C = 200pF, R = 0)
VCC = 3.3V ± 0.3V, Normal Range
VCC = 2.7V to 3.6V, Extended Range
VCC = 2.5V ± 0.2V
CMOS power levels (0.4µ W typ. static)
Rail-to-Rail output swing for increased noise margin
Available in SOIC, SSOP and TSSOP packages
This quadruple bus buffer gate is built using advanced dual metal CMOS
technology. The ALVC125 features independent line drivers with 3-state
outputs. Each output is disabled when the associated output-enable (OE)
input is high.
The ALVC125 has been designed with a ±24mA output driver. This
driver is capable of driving a moderate to heavy load while maintaining
speed performance.
APPLICATIONS:
Drive Features for ALVC125:
– High Output Drivers: ±24mA
– Suitable for heavy loads
• 3.3V High Speed Systems
• 3.3V and lower voltage computing systems

NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM
RATINGS may cause permanent damage to the device. This is a
stress rating only and functional operation of the device at these or
any other conditions above those indicated in the operational sections
of this specification is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect reliability.
