Description

AI
This octal buffer/line driver is designed for 1.65-V to 3.6-V VCCoperation. 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 VCCthrough 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.
