SR-latch.
Hi Thunderchild,
I think I've got a rough idea what sort of integrated circuit you are
looking for, probably the NE521 or NE522 from Signetics, both obsolete.
Now there is only one that comes close to these older chips, the LM361.
**broken link removed**
It has only one comparator and two internal nand gates. Both gates have
an output and a strobe input which can be used externally. So if you want
to copy the internal structure of the 555 you gonna need two LM361's
and combine one gate from each circuit to form a SR-latch. The LM361's
operate from +/- 15 volts opamp supplies AND a separate +5 volts
for the digital part of the circuit.
