SN74ALS245ADWR Description

Short technical summary and product information.

The SN74ALS245ADWR from Texas Instruments is an active octal bus transceiver with 3-state outputs, designed for efficient asynchronous two-way communication between data buses. This device supports a wide operating voltage range of 4.5V to 5.5V, making it suitable for various logic systems.

 

Key electrical characteristics include 8 channels, TTL input and output types, and a maximum propagation delay of 5.5 ns at 5V. The transceiver features non-inverting logic and provides 3-state outputs to directly drive bus lines. It operates within a temperature range of 0°C to 70°C.

 

The SN74ALS245ADWR is available in a 20-SOIC package, designed for surface mounting. Its robust design and features like pnp inputs reducing DC loading make it a reliable choice for data transmission applications requiring isolation and control.

 

This component is part of the ALS (Advanced Low-power Schottky) technology family, known for its high speed and low power consumption. The control functions minimize external timing requirements, simplifying circuit design.
