description
These bus buffers are designed specifically for low-voltage (3.3-V) V
CC
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 V
CC
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 –55
°
C to 125
°
C. The
SN74LVT125 is characterized for operation from –40
°
C to 85
°
C.
