DESCRIPTION/ORDERING INFORMATION
This octal buffer/line driver is designed for 1.65-V to 3.6-V VCC operation.
The SN74ALVCH244 is organized as two 4-bit line drivers with separate output-enable (OE) inputs. When OE is
low, the device passes 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.
Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors
with the bus-hold circuitry is not recommended.
