Hardware Question

Thomas Reilly

Hi, I building a project at the minute and have noticed that my store manager has given me the wrong latch for my external memory. He gave me the SN74LS73AN while the one he should of gave me is the SN74LS373AN. I have the HD74LS245P and was wondering if I could use this instead of the SN74LS373AN latch. It says its a octal bus transceiver. Is that the same as a latch. Operating wise it looks the same.

Thanks,
Thomas Reilly.

    for a shark and a dolphin "Operating wise it looks the same" which would you rather swim with?

    a transceiver and a latch are TOTALLY different animals. you may want to use a 573 instead of the 373 it is the same chip but has a much more convenient pinout. BUT 373 and 573 are the ONLY useable chips.

    anyhow Keil is not in hardware, direct non-Keil ;51 questions to 8052.com
