I am looking for a data sheet for an antique MHTL (HTL, essentially DTL, diode transistor logic). Part number MC667TL . . . I can't find a data sheet that shows where the timing capacitor and timing resistor connect. I have the following sheet :
From a generic data sheet page 23, but doesn't show the capacitor and resistor pin connections. Anybody ?
Reverse engineering shows that pins 1 and 13 are the inputs to trigger. Also that pins 2 and 12 are outputs. Then I find a capacitor from (9) to (11). And a capacitor from (11) to ground. (power is Vcc 14 and gnd 7)
