Product Overview
Motorola MC789P hex inverter integrated circuit from the MC700P Resistor-Transistor Logic (MRTL) family. Built in a 14-pin dual in-line package with gold-plated pins, this vintage component provides six independent inverting gates designed for low-voltage digital circuits and legacy electronics maintenance.
Key Features
- Six independent inverting logic gates in one package
- Motorola Resistor-Transistor Logic (MRTL / MC700P series) architecture
- 14-pin through-hole DIP package configuration
- Gold-plated terminal pins for corrosion resistance and reliable contact
- Typical supply voltage range of 3.0 V to 3.6 V DC
- Commercial operating temperature range of 0°C to +75°C
- Package marked with Motorola logo, part number MC789P, and 7205 date code
Applications
- Replacing failed inverters in vintage 1970s test equipment, industrial controllers, and early computing hardware.
- Restoring classic electronic musical instruments and synthesizers requiring original RTL circuit logic.
- Bench prototyping period-accurate digital demonstrations and educational computing systems.
Frequently Asked Questions
What is the recommended operating voltage for the MC789P?
The MC789P operates with a typical Vcc supply between 3.0 V and 3.6 V DC, consistent with standard Motorola MC700P series specifications.
Can this IC be directly connected to modern 5V TTL logic?
Because MRTL logic thresholds and operating voltages differ from 5V TTL systems, proper level-shifting or interfacing circuitry is required when connecting between families.
Why buy a single verified MC789P instead of a bulk surplus lot?
Purchasing an individual, verified NOS component ensures you receive the exact part with straight gold leads, avoiding the uncertainty and excess cost of untested bulk pulls. Orders ship for an $8 flat rate, qualify for free shipping at $28, and ship the same or next business day from our Idaho warehouse.
Gold leads and 1970s resistor-transistor logic from the early days of integrated computing. When a legacy machine needs a period-correct repair, the right vintage component keeps the clock running.
