IDT74ALVCH244

DESCRIPTION:

The ALVCH244 octal buffer/driver is built using advanced dual metal

CMOS technology. The ALVCH244 is organized as two 4-bit line drivers

with seperate 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.

To ensure the high-impedance state during power up or power down,

should be tied to V

through a pullup resistor; the minimum value of

the resistor is determined by the current-sinking capability of the driver.

The ALVCH244 has been designed with a ±24mA output driver. This

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

speed performance.

The ALVCH244 has a “bus-hold” which retains the inputs’ last state

whenever the input bus goes to a high impedance. This prevents floating

inputs and eliminates the need for pull-up/down resistors.

Drive Features for ALVCH244:

– High Output Drivers: ±24mA

– Suitable for heavy loads

APPLICATIONS:

• 3.3V High Speed Systems

• 3.3V and lower voltage computing systems
