Description

The 'LVT16245B devices are 16-bit (dual-octal) noninverting 3-state transceivers designed for low-voltage (3.3-V) VCC operation, but with the capability to provide a TTL interface to a 5-V system environment.

LVT16245B 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 on the logic level at the direction-control (DIR) input. The output-enable (OE) input of LVT16245B can be used to disable the devices so that the buses are effectively isolated.

When VCC is between 0 and 1.5 V, the LVT16245B is in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 1.5 V, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor LVT16245B is determined by the current-sinking capability of the driver.
