SN74LVTH16245ADL .

The SN74LVTH16245ADL is a 16-bit non-inverting Bus Transceiver designed for low-voltage (3.3V) VCC operation, but with the capability to provide a TTL interface to a 5V system environment. It is 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 un-driven inputs at a valid logic state. Use of pull-up/pull-down resistors with the bus-hold circuitry is not recommended.

• Support mixed-mode signal operation
• IOFF and power-up 3-state support hot insertion
• Distributed VCC and GND pins minimize high-speed switching noise
• Flow-through architecture optimizes PCB layout
• Bus hold on data inputs eliminates the need for external pull-up/pull-down resistors
• Support unregulated battery operation down to 2.7V
• State-of-the-art advanced BiCMOS technology design for 3.3V operation/low static-power dissipation
• <lt/>0.8V at VCC = 3.3V, TA = 25°C VOLP (output ground bounce)
• Green product and no Sb/Br
