description

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

The ´LVT241 are organized as two 4-bit line drivers with separate output-enable (1OE\, 2OE) inputs. When 1OE\ is low or 2OE is high, the devices pass data from the A inputs to the Y outputs. When 1OE\ is high or 2OE is low, the outputs are in the high-impedance state.

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

To ensure the high-impedance state during power up or power down, OE\ should be tied to V_CC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. OE should be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.

The SN74LVT241 is available in TI's shrink small-outline package (DB), which provides the same input/output (I/O) pin count and functionality of standard small-outline packages in less than half the printed-circuit-board area.

The SN54LVT241 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74LVT241 is characterized for operation from -40°C to 85°C.
