Product Overview
Microsystems International ML741CT delivers general-purpose operational amplification in a hermetic 8-lead metal can package with internal frequency compensation. Built on classic 741 architecture, the circuit provides short-circuit protection, offset null capability, and unity-gain stability. This commercial-grade component matches standard 741 pinouts and provides an authentic period replacement for legacy test gear, analog synthesizer sub-assemblies, and industrial control stages.
Key Features
- 8-lead TO-99 hermetic metal can package with orientation tab locating pin 8
- Straight gold-plated leads for corrosion resistance and reliable socketing or soldering
- Internal frequency compensation for stable unity-gain operation
- Output short-circuit protection
- Offset null capability via pins 1 and 5
- Direct cross-reference equivalent to LM741H and MC1741CG metal-can devices
Applications
- Restoring vintage analog test equipment, power supplies, or preamplifiers requiring authentic 1970s metal-can ICs
- Servicing legacy industrial control circuits designed around circular 8-pin op amp footprints
- Building retro analog synthesizers, guitar effects pedals, or instrumentation stages on breadboards
Frequently Asked Questions
How is the pinout oriented on the metal can?
The package features an indexing tab on the metal rim that aligns directly with pin 8, allowing quick identification when populating sockets or printed circuit boards.
What industry-standard part numbers interchange with the ML741CT?
The ML741CT is a direct form, fit, and function replacement for standard 8-pin metal-can 741 op amps, including the National Semiconductor LM741H and Motorola MC1741CG.
How many op amps are integrated into each package?
The ML741CT contains a single operational amplifier per can, so dual or quad op amp circuits require multiple individual units.
Gold-plated leads and a hermetic metal can built in an era when analog chips were made to last. For keeping vintage boards authentic or running genuine 1970s silicon on the bench, this op amp drops right into the circuit.
