The 'LVTH16245A 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.
The devices are designed for asynchronous communication between two data buses. The logic levels of the
direction-control (DIR) input and the output-enable (OE) input activate either the B-port outputs or the A-port
outputs or place both output ports into the high-impedance mode. The device transmits data from the A bus to
the B bus when the B-port outputs are activated, and from the B bus to the A bus when the A-port outputs are
activated. The input circuitry on both A and B ports is always active and must have a logic HIGH or LOW level
applied to prevent excess ICC and ICCZ.
Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown
resistors with the bus-hold circuitry is not recommended.
When VCC is between 0 and 1.5 V, the devices are 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 is determined by the current-sinking capability of the driver.
These devices are fully specified for hot-insertion applications using Ioff and power-up 3-state. The Ioff circuitry
disables the outputs, preventing damaging current backflow through the devices when they are powered down.
The power-up 3-state circuitry places the outputs in the high-impedance state during power up and power down,
which prevents driver conflict.
