I am working on an HP59405, which is the HPIB
interface for the HP9830
'calculator'. On the PCB are 2 chips which cross to something
called an
MC1806. This is not in any of my Motorola databooks.
Does anyone have a databook that lists it?

This is the short description:
Part Number = MC1806P
Description = 2-Input AND-Function Logic Gate
Manufacturer = Motorola
Circuits Per Package = 4
t(PLH) Maximum (S) = 35n
P(D) Max.(W) Power Dissipation = 75m
Vsup Nom.(V) Supply Voltage = 5.0
Status = Discontinued
Package = TO-116
Pins = 14
Military = N
Technology = DTL
The attached PDF is a overall listing of the Motorola DTL. Hope this
helps.
CRC?

Thanks, (and thanks to others who've offered me data. This really is a
great list!).
An AND gate makes sense now that I've realised that the 9830 has active
high data output lines and active low data input lines on the I/O bus
(!). This gate needs to be a non-inverting type where the output can be
forced low -- that is an AND gate.
