LJ245A Description

Short technical summary and product information.

The LJ245A from Texas Instruments is an 8-bit octal bus transceiver featuring 3-state outputs, facilitating bidirectional data transfer between buses. It is designed for asynchronous communication and supports voltage translation between a 3.3V environment (B port, VCCB) and a 5V environment (A port, VCCA). The control circuitry, including direction-control (DIR) and output-enable (OE) inputs, is powered by VCCA.

 

Key electrical characteristics include a continuous output current of ±50mA and a continuous current through VCCA or GND of ±100mA. The device offers protection features such as latch-up performance exceeding 250mA per JESD 17 and ESD protection exceeding JESD 22 standards, including 2000V Human-Body Model, 200V Machine Model, and 1000V Charged-Device Model.

 

The LJ245A is supplied in an SOP package. Its design allows for isolation of buses when the output-enable input is disabled. The control inputs' VIH/VIL levels are referenced to the VCCA voltage, providing flexibility in system design.
