SN74ALS621A-1N Description

Short technical summary and product information.

The Texas Instruments SN74ALS621A-1N is an octal bus transceiver 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 output current capability of 24mA. The operating temperature range is specified from 0°C to 70°C.

 

This transceiver is available in a 20-PDIP package suitable for through-hole mounting. The SN74ALS621A-1N is characterized for operation from 0°C to 70°C. The -1 versions are identical to standard versions except for an increased recommended maximum IOL of 48 mA.

 

Designed for flexibility, the control-function implementation allows for maximum timing flexibility. The output-enable inputs can disable the device, effectively isolating the buses. The dual-enable configuration enables the transceivers to store data by simultaneously enabling OEAB and OEBA.
