IDT74ALVC244

3.3V CMOS OCTAL BUFFER/DRIVER WITH 3-STATE OUTPUTS

INDUSTRIAL TEMPERATURE RANGE

3.3V CMOS OCTAL

BUFFER/ DRIVER WITH

3-STATE OUTPUTS

FEATURES:

DESCRIPTION:

IDT74ALVC244

• 0.5 MICRON CMOS Technology

• Typical t

SK(o)

(Output Skew) < 250ps

• ESD > 2000V per MIL-STD-883, Method 3015; > 200V using

machine model (C = 200pF, R = 0)

• V

= 3.3V ± 0.3V, Normal Range

• V

= 2.7V to 3.6V, Extended Range

• V

= 2.5V ± 0.2V

• CMOS power levels (0.4µ W typ. static)

• Rail-to-Rail output swing for increased noise margin

• Available in QSOP, SOIC, SSOP, and TSSOP packages

This octal buffer/driver is built using advanced dual metal CMOS

technology. The ALVC244 is organized as two 4-bit line drivers with

separate output-enable (OE) inputs. When

is low, the device passes

data from the A inputs to the Y outputs. When

is high, the outputs are in

the high-impedance state.

The ALVC244 has been designed with a ±24mA output driver. This

driver is capable of driving a moderate to heavy load while maintaining

speed performance.

DRIVE FEATURES:

• High Output Drivers: ±24mA

• Suitable for Heavy Loads

APPLICATIONS:

• 3.3V high speed systems

• 3.3V and lower voltage computing systems
