  1. Talk about a hard-to-find chip! We're trying to find the pinouts of this
    TTL chip made by Texas Instruments: SN74118. A web search indicates it's
    some type of RS latch, but for testing purposes the pinout would really
    help.

    Thanks!!!

  2. Are you certain of the number? I find no reference to a 74118 in my
    1981 Texas Instruments TTL databook.

    (I'll check at work tomorrow - I have a somewhat newer TI book
    there...)

  4. I can't find the SN74118 in any of our databooks, or on TI's website -
    but a Google search finds a few hits, including some for sale at
    www.donberg.ie/descript/s/sn74118.htm - perhaps they can provide a
    datasheet.
