Hi all,

What is the difference between the SN74ALS245A-1DBR and the SN74ALS245ADBR?

I have determined that SN74ALS245A-1DBR is not EOL from the following thread. However, I cannot view it from TI.com.

It is not mentioned in the data sheet. Can you give me the information of SN74ALS245A-1DBR?

Best Regards,

Ryusuke

The datasheet says:

The -1 version of the SN74ALS245A is identical to the standard version, except that the recommended maximum I_OL is increased to 48 mA.

That thread is five years old. The SN74ALS245A-1DBR does not exist on the TI web page.

Here is a search for similar devices in the SSOP package: General-purpose transceivers product selection; you probably want the CY74FCT245T or SN74ABT245B.
