Description

These octal buffers and line drivers SN74LVT244 are designed specifically for low-voltage (3.3-V) VCC operation, but with the capability to provide a TTL interface to a 5-V system environment.

The SN74LVT244 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.

Active bus-hold circuitry is provided by SN74LVT244 to hold unused or floating data inputs at a valid logic level.

About SN74LVT244,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 SN74LVT244 is packaged in TI's shrink small-outline package (DB), which provides the same I/O pin count and functionality of standard small-outline packages in less than half the printed-circuit-board area.

The SN54LVT244 is characterized for operation over the full military temperature range of 55°C to 125°C. The SN74LVT244 is characterized for operation from 40°C to 85°C.
