4727BPC — Counter |
|
|
 |
The 4727B integrated circuit contains seven clocked D-type
Flip-Flops.
Each flip-flop's Q output
is wired to its Data input so that each operates as a
frequency divider.
There are three single flip-flops and two 2-stage flip-flops in the
chip, making
seven dividers in total.
Including the frequency of the clock, that covers all eight
musical octaves.
If the clock frequency is High C, for example, one 4727 chip can
produce every other C in the musical spectrum.

pulse wave simultaneously.
It's used in many vintage synths,
including models made by Sequential Circuits, Oberheim, and Moog.

RC4136N — Quad Op Amp |
|
|
|
Each of the four op amps in the RC4136 is electrically similar to the
industry standard 741 op amp. Except the 4136 has no
offset-null pins.
A high input voltage range and the absence of latch-up
make this chip ideal for voltage-follower applications.
The 4136 quad op amp has a non-standard pin-out, making
substitute types hard to find.

TDA0470 — Organ Gate |
|
|
|
The TDA0470-D is an improved, pin compatible version of the TDA 0470
12-Transistor Array and is particularly suitable for use in
electronic organs.
Its 12 parallel transistors each replace
a mechanical key contact, making it possible to reduce the number of mechanical contacts per key
(there are up to 10 in a standard organ) to a single contact per key.
Each of the twelve emitters
is fed by its own tone signal and their sum is available at the common collector
pin.
Clamping diodes on the emitter inputs reduce capacitive crosstalk among the transistors.
