SN74ALS245ADBR Description

Short technical summary and product information.

The Texas Instruments SN74ALS245ADBR is an octal bus transceiver belonging to the ALS (Advanced Low-power Schottky) family. It is designed for asynchronous two-way communication between data buses, allowing 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 features 8 channels with non-inverting logic. It supports TTL input and output types and operates over a voltage range of 4.5V to 5.5V. Key electrical characteristics include a maximum output current (IOL) of 24mA and a maximum output current (IOH) of -15mA. The maximum propagation delay (tpd) is specified as 5.5ns at 5V, with a general range of 10-50ns.

 

The SN74ALS245ADBR is housed in a 20-SSOP (Shrink Small Outline Package) with a width of 5.30mm, designed for surface mounting. It operates within a temperature range of 0°C to 70°C. The device is suitable for applications requiring efficient data bus management and signal isolation.

 

Environmental compliance includes RoHS3 compliance, an MSL rating of 1 (unlimited), and REACH unaffected status. The part is supplied in tape and reel packaging with a reel diameter of 330mm and a reel width of 16.4mm.
