Im trying to repair a schlage handkey which wont boot. I looked at the main board and noticed the chip below. The chip above it is the same part number but when I try to look it up I get nothing. How do I make sense of the markings?
This is a standard 74AC32 quad OR gate. The logo is from TI.
The code above is likely a date code or lot code. The code below is the actual part number (74 is implied since its a member of the eternal 7400 series logic family).
Here's the TI datasheet: http://www.ti.com/lit/ds/symlink/sn54ac32.pdf
See page 5 of the datasheet for an explanation of the package markings. This is a SOIC-14 package and thus only contains the letters "AC32".
