FZH111A Datasheet – Quad 2-input NAND Gate – Siemens

Part Number : FZH111A

Function : Quad 2-input NAND Gate

Package : DIP 16P

Manufacturers : Siemens AG

Image :


Description :

The chips used DTL (Diode-Transistor Logic) which was a predessesor of of the TTL (Transistor-Transistor-Logic) manufactured in the late 60s. If neccesary I could provide basic data and pinout from an old Valvo databook but it might take some days to find it.
