SN74LVTH2245PW

The SN74LVTH2245PW is an octal bus transceiver designed for low-voltage 3.3-V VCC operation, offering a TTL interface to a 5-V system environment. This device facilitates asynchronous communication between data buses, transmitting data from the A bus to the B bus or vice versa, controlled by the direction-control (DIR) input. The output-enable (OE) input allows for disabling the devices, effectively isolating the buses.

Key electrical specifications include 8 channels, TTL/CMOS input type, and LVTTL output type. It supports a voltage range of 2.7V to 3.6V and operates within a temperature range of -40°C to 85°C. Features such as balanced outputs, mixed-mode signal operation, unregulated battery operation down to 2.7V, and integrated series resistors on B-port outputs are included. The transceiver also supports I off and power-up 3-state, hot insertion, and bus hold on data inputs, eliminating the need for external pullup/pulldown resistors.

Packaged in a 20-TSSOP, the SN74LVTH2245PW is suitable for surface mount applications. The carrier material report indicates a TSSOP package type with specific dimensions for the tube packaging. ESD protection exceeds 2000-V for the human-body model and 200-V for the machine model, with latch-up performance exceeding 500 mA per JESD 17.
