Part Number: SN74ALS642A-1

Is the IOL low-level output current of SN 74 ALS 642 A -1 NSR and SN 74 ALS 642 A -1 DW 24 mA or 48 mA?

Is this current per pin of the IC or the whole IC?

All devices with the -1 suffix have 48 mA.

These specifications are per pin.

Is the IC whose device printing is "G624A-1, TI-logo, 78KG4, CX1T" the IC Iinquired about SN74ALS642A-1 ?

If it is another IC, please tell me its name.

The datasheet shows the markings. The -1 devices are marked with "-1".

Hey Terao,

The datasheet lists the SN74ALS642A-1 DW package top side marking as being 'ALS642A-1'
I couldn't tell you what G624A-1 is. There isn't a device in our portfolio ending in 624A-1 so I haven't been able to track it down.
Do you believe you received the wrong device?

Thanks,
Rami
