Product Overview
Motorola MC790P is a dual J-K flip-flop integrated circuit from the Motorola Resistor-Transistor Logic (MRTL) family, housed in a standard 14-pin dual in-line package. Designed for digital counting, frequency division, and control circuits of the early 1970s, it provides two independent bistable elements with direct clear inputs and negative-edge clock triggering.
Key Features
- Logic family: Motorola Resistor-Transistor Logic (MRTL) MC700P series
- Function: Dual J-K flip-flop with direct reset inputs
- Triggering: Negative edge-triggered
- Maximum toggle frequency: 4 MHz
- Package: 14-pin DIP (DIP-14)
- Lead finish: Gold-plated leads
- Markings: MC790P and date code 7204
Applications
- Restoring vintage 1970s digital test equipment, frequency counters, and legacy instrumentation requiring original MRTL components.
- Retrocomputing repairs and historical logic rebuilds requiring exact period electrical characteristics.
- Modular synthesizer prototyping and vintage clock divider experiments built by audio hobbyists.
Frequently Asked Questions
What logic family does the MC790P belong to?
The MC790P is a member of Motorola's MRTL (Resistor-Transistor Logic) MC700P/MC800P series, which uses RTL voltage levels rather than standard 5V TTL logic levels.
What do the stamped markings indicate?
The top surface is stamped with the Motorola logo, part number MC790P, and date code 7204, which designates production during the fourth week of 1972.
Why purchase an individual Motorola MC790P here rather than an assorted surplus lot?
You receive the exact unit shown with clean, unbent gold leads, avoiding untested pulls or mixed date lots. Flat-rate shipping is $8, orders over $28 ship free, and your order leaves our Idaho warehouse the same or next business day.
Nothing quite matches the sharp look of 1972 gold leads ready to bring a classic logic rail back to life. Plug it into your circuit and let clean, steady clock cycles do the talking.
