SN74ALS621AN Description

Short technical summary and product information.

The SN74ALS621AN is an octal bus transceiver manufactured by Texas Instruments, designed for asynchronous two-way communication between data buses. This device allows data transmission from the A bus to the B bus or vice versa, controlled by output-enable inputs. It offers a choice of true or inverting logic and features a local bus-latch capability.

 

Key electrical characteristics include an operating voltage range of 4.5V to 5.5V and an operating temperature range of 0°C to 70°C. The output type is open collector, with a specified current of 24mA. The transceiver is configured as a single 8-bit element.

 

This component is available in a 20-PDIP package and is designed for through-hole mounting. The standard package is a 20-DIP with dimensions of 0.300 inches (7.62mm). The SN74ALS621AN is suitable for applications requiring flexible data bus communication and storage capabilities.
