SN74ALS245ANSR Description

Short technical summary and product information.

The SN74ALS245ANSR from Texas Instruments is an active octal bus transceiver with 3-state outputs, designed for 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, non-inverting logic, and output current capabilities of 24mA IOL and -15mA IOH. The transceiver features over-voltage tolerant inputs and pnp inputs that reduce DC loading. The direction-control (DIR) input determines data flow direction, while the output-enable (OE) input can disable the device, effectively isolating the buses.

 

Packaged in a 20-SOIC format, the SN74ALS245ANSR is designed for surface mounting. It operates within a temperature range of 0°C to 70°C (TA). This component is part of the ALS (Advanced Low-power Schottky) technology family, offering high speed with a typical propagation delay of 5.5 ns at 5V.

 

The SN74ALS245ANSR is ideal for applications requiring bidirectional data transfer between different bus systems where control over data flow and bus isolation is necessary.
