SN74HCT245DWR Description

Short technical summary and product information.

The SN74HCT245DWR from Texas Instruments is an active octal bus transceiver designed for asynchronous two-way communication between data buses. This device features 8 channels and non-inverting logic. It operates within a voltage range of 4.5V to 5.5V and offers high-current, 3-state outputs capable of driving bus lines directly or up to 15-LSTTL loads.

 

Key electrical characteristics include a typical propagation delay of 14 ns, a maximum supply current of 80 µA, and a low input current of 1 µA. The output current is rated at ±6 mA at 5V. The transceiver is housed in a 20-SOIC package and is designed for surface mounting.

 

This component is suitable for applications requiring bidirectional data transfer between buses, with the direction controlled by the DIR input and the outputs disabled via the OE input. Its TTL-compatible inputs and CMOS outputs make it versatile for various interfacing needs.
