SN74HCT245NSR Description

Short technical summary and product information.

The Texas Instruments SN74HCT245NSR is an active octal bus transceiver with tri-state outputs, designed for asynchronous two-way communication between data buses. This device supports a wide operating voltage range of 4.5 V to 5.5 V and operates efficiently with low power consumption, drawing a maximum of 80 µA.

 

Key electrical characteristics include TTL-compatible inputs and CMOS outputs, with a typical propagation delay of 14 ns. The transceiver provides balanced outputs and a high-current drive capability of ±6 mA at 5 V, capable of driving bus lines directly or up to 15 LSTTL loads. It features a low input current of 1 µA maximum.

 

The SN74HCT245NSR is available in a 20-SOIC package, suitable for surface mount applications. The device's control functions, including direction-control (DIR) and output-enable (OE) inputs, minimize external timing requirements, allowing data transmission in either direction between bus A and bus B, or disabling the device to isolate the buses.

 

This transceiver is rated for an operating temperature range of -40°C to 125°C, making it suitable for various industrial applications. Its design facilitates efficient data transfer in systems requiring flexible bus communication.
