SN74ALS245A Description

Short technical summary and product information.

The SN74ALS245A from Texas Instruments is an octal bus transceiver featuring 3-state outputs that drive bus lines directly. Designed for asynchronous two-way communication, it facilitates data transmission between data buses based on the logic level at the direction-control (DIR) input. The output-enable (OE) input allows for disabling the device, effectively isolating the buses.

 

This transceiver operates with a VCC range of 4.5 V to 5.5 V and offers a maximum propagation delay (tpd) of 5.5 ns at 5 V. It has a maximum IOL of 24 mA and a maximum IOH of -15 mA. The device is rated for an operating temperature range of 0°C to 70°C.

 

Available in various packages including PDIP (N), SOIC (DW), SOP (NS), and SSOP (DB), the SN74ALS245A is suitable for a wide range of applications requiring efficient data bus interfacing. Its design minimizes external timing requirements, making integration simpler.
