SN74HC245DWR Description

Short technical summary and product information.

The Texas Instruments SN74HC245DWR is an octal bus transceiver designed for asynchronous two-way communication between data buses. This device features 3-state outputs and operates over a wide voltage range from 2V to 6V.

 

Key electrical characteristics include a typical propagation delay (tpd) of 12 ns and a high-current output drive capability of ±6 mA at 5V. It also boasts low power consumption, with a maximum ICC of 80 μA, and low input current of 1 μA maximum.

 

The SN74HC245DWR is suitable for applications requiring direct bus line driving or interfacing with up to 15 LSTTL loads. The transceiver functionality allows data transmission in either direction between bus A and bus B, controlled by the direction-control (DIR) input. The output-enable (OE) input can disable the device, effectively isolating the buses.

 

This component is available in a 20-SOIC package and is designed for surface mount applications. It operates within an ambient temperature range of -40°C to 85°C.
