CD4046B CMOS Micropower Phase-Locked Loop (PLL)
Micropower phase-locked loop consisting of a linear voltage-controlled oscillator (VCO) and two different phase comparators with common signal-input and comparator-input.
LM1875 20W Hi-Fi Audio Power Amplifier
Monolithic power amplifier offering very low distortion (0.015% THD) and high-quality performance for consumer audio applications. Capable of delivering 20W into a 4Ω or 8Ω load.
LM7809 9V 1.5A Positive Voltage Regulator
Three-terminal positive linear voltage regulator with fixed 9V output. Capable of supplying over 1.5A output current with internal thermal overload and short-circuit current limiting protection.
LM7815 15V 1.5A Positive Voltage Regulator
Standard 3-terminal positive voltage regulator with fixed 15V output. Commonly used in dual-rail audio equipment and op-amp power supplies in combination with LM7915.
LM7912 -12V 1.5A Negative Voltage Regulator
Three-terminal negative voltage regulator with fixed -12V output. Note: Pinout differs from LM78xx: Pin 1 is Ground, Pin 2 is Input, and the heatsink tab is connected to Input.
OP07 Ultra-Low Offset Voltage Operational Amplifier
Very low input offset voltage (75µV max) operational amplifier with low drift and high open-loop gain (300V/mV), making it the classic standard for precision instrumentation.

CD4040B CMOS 12-Stage Binary Ripple Counter
12-stage binary ripple counter with master reset. Advances one count on the negative-going transition of each clock pulse. Common for frequency dividers and timers.
Frequently Asked Questions & Transparency
Helpful information about data sources, usage, and privacy
Where does the pinout data and technical specification come from?
The pinout data and technical specifications are based on official manufacturer datasheets as well as publicly available documentation and community resources. As PinoutDatabase is an independent project maintained by me as an individual, I strive for high accuracy, though inadvertent mistakes can still happen.
Can I use the graphics and how are they created?
The SVG vector files and PNG graphics are free to download and use for private/personal purposes. Depending on the component, the diagrams are either crafted manually or generated automatically based on package footprint and pin definitions.
Found an error or missing a component? How can I give feedback?
Community feedback is always appreciated! If you spot an error or are missing a specific component, please use the 'Report Issue' button directly on that component's page or send me a message via the contact form.
Is the site free to use and how is privacy handled?
Currently, using PinoutDatabase is completely free and requires no registration. All interactive web tools run entirely client-side inside your browser. Detailed information regarding data processing can be found directly on our Privacy Policy page.
