SN74HC245NSR Description

Short technical summary and product information.

The Texas Instruments SN74HC245NSR is an active octal bus transceiver designed for asynchronous two-way communication between data buses. It features 3-state outputs capable of driving bus lines directly or up to 15 LSTTL loads.

 

This transceiver operates over a wide voltage range of 2V to 6V, with a typical propagation delay of 12 ns. It offers balanced outputs and high speed, making it suitable for various interfacing applications. The device consumes low power, with a maximum ICC of 80 μA and a low input current of 1 μA.

 

The SN74HC245NSR is available in a 20-SOIC package, designed for surface mounting. Its operating temperature range is -40°C to 85°C (TA). The control function implementation minimizes external timing requirements, 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.

 

Key electrical characteristics include an output current of ±6 mA at 5V and 8 channels with 8 bits per channel. The input and output types are CMOS.
