The SN74LVTH245APWR is an octal bus transceiver from Texas Instruments, designed for low-voltage (3.3V) VCC operation while providing a TTL interface to a 5V 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.
Key electrical specifications include a voltage range of 2.7V to 3.6V, with IOL and IOH currents of 64mA and -64mA respectively. The transceiver supports mixed-mode signal operation, allowing 5V input and output voltages with a 3.3V VCC. It also supports unregulated battery operation down to 2.7V and features I off and Power-Up 3-State support.
Packaged in a 20-TSSOP, the SN74LVTH245APWR is suitable for surface mounting. It offers robust performance with latch-up exceeding 500mA per JESD 17 and ESD protection exceeding 2000V (HBM) and 200V (MM). The active bus-hold circuitry on data inputs eliminates the need for external pullup/pulldown resistors.
This transceiver is ideal for applications requiring bidirectional data transfer between buses operating at different voltage levels or requiring isolation during power-up or power-down sequences. The output-enable (OE) input can disable the devices, effectively isolating the buses.
