Hi
What I'd like to know is where is a good source for DTL chips?
While most can be replaced with a TTL, except the 8 input nand.
It can be replaced if it is just used as an 8 input but if the
circuit uses the diode expansion pin, you must use the DTL chip.
Also, I'd love to know what numbers were used for this part
by the different manufactures? It seems that each had their own
numbering system.
Anchor Electronic has a few DTLs but I have no cross reference to
know what they are.
