descriptionThe ’LVT16245A are 16-bit (dual-octal) noninverting 3-state transceivers designed for low-voltage (3.3-V) VCCoperation, but with the capability to provide a TTL interface to a 5-V system environment.
These devices can be used as two 8-bit transceivers or one 16-bit transceiver. They allow data transmission
from the A bus to the B bus or from the B bus to the A bus, depending upon the logic level at the direction-control
(DIR) input. The output-enable (OE) input can be used to disable the device so that the buses are effectively
isolated.
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.
