SN74LS642DW Description

Short technical summary and product information.

The Texas Instruments SN74LS642DW is an octal bus transceiver designed for efficient asynchronous two-way communication between data buses. This device features open collector outputs and operates within a voltage range of 4.75V to 5.25V.

 

With a specified operating temperature range of 0°C to 70°C, the SN74LS642DW is suitable for various industrial applications. It is housed in a 20-SOIC package, designed for surface mounting.

 

The transceiver's functionality is controlled by a direction control (DIR) input, allowing data transmission from bus A to bus B or vice versa. An enable input (G) can disable the device, effectively isolating the buses. The -1 versions of related parts offer an increased I OL rating of 48 mA, while this specific SN74LS642DW is characterized for operation from 0°C to 70°C.
