SN74ABT162245DLR

The Texas Instruments SN74ABT162245DLR is a 16-bit non-inverting 3-state bus transceiver designed for synchronous two-way communication between data buses. This device supports a voltage range of 4.5V to 5.5V and features TTL input and output types. It can function as two independent 8-bit transceivers or a single 16-bit transceiver, allowing bidirectional data flow controlled by the DIR input.

The transceiver includes features such as damping resistors, over-voltage tolerant inputs, and partial power-down capability (Ioff). It is characterized by very high speed operation with propagation delays between 5-10ns. The device is available in a 48-SSOP package and is suitable for surface mounting.

Key electrical characteristics include IOL max of 64mA and IOH max of -32mA. The A-port outputs are designed to source or sink up to 12mA. The Widebus family member offers distributed VCC and GND pins to minimize switching noise and a flow-through architecture for optimized PCB layout. Latch-up performance exceeds 500mA per JESD 17, and ESD protection exceeds 2000V Human-Body Model (A114-A) and 200V Machine Model (A115-A).

This transceiver is ideal for applications requiring high-speed data transfer and bus isolation. Its design considerations include minimizing high-speed switching noise and optimizing PCB layout.
