SN74LS245NSR Description

Short technical summary and product information.

The Texas Instruments SN74LS245NSR is an octal bus transceiver designed for asynchronous two-way communication between data buses. It features 3-state outputs that drive bus lines directly and PNP inputs that reduce DC loading. The device allows data transmission from the A bus to the B bus or vice versa, controlled by the direction-control (DIR) input. The output-enable (OE) input can disable the device, effectively isolating the buses.

 

This transceiver operates within a voltage range of 4.75V to 5.25V and has an operating temperature range of 0°C to 70°C. Key electrical characteristics include a typical propagation delay of 8 ns port to port, and current ratings of 15mA and 24mA. It is configured as a single element with 8 bits per element and offers a non-inverting logic type.

 

The SN74LS245NSR is supplied in a 20-SOIC (0.209", 5.30mm Width) surface mount package. Its design incorporates hysteresis at bus inputs to improve noise margins. Applications include building automation, electronic point of sale, factory automation and control, and test and measurement systems.
