These bus buffers 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 LVT125 feature independent line drivers with 3-state outputs. Each output is in the high-impedance state when the associated output-enable (OE) input is high. 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 VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. The SN74LVT125 is available 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 SN54LVT125 is characterized for operation over the full military temperature range of 55C to 125C. The SN74LVT125 is characterized for operation from 40C to 85C. |
