DESCRIPTION:
The ALVCH244 octal buffer/driver is built using advanced dual metal
CMOS technology. The ALVCH244 is organized as two 4-bit line drivers
withseperateoutput-enable(OE)inputs.WhenOEislow,thedevicepasses
data from the A inputs to the Y outputs. When OE is high, the outputs are in
the high-impedance state.
To ensure the high-impedance state during power up or power down,
OE should be tied to VCC 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.
