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.
TIP31C 100V 3A NPN Power Transistor
Medium-power epitaxial-base NPN silicon transistor in TO-220 package. Designed for general-purpose switching and amplifier applications. Complementary to TIP32C.
TIP32C 100V 3A PNP Power Transistor
Medium-power epitaxial-base PNP silicon transistor in TO-220 package. Designed for general-purpose switching and amplifier applications. Complementary to TIP31C.
74HC244 Octal Buffer/Line Driver with 3-State Outputs
Octal non-inverting buffer and line driver designed to drive bus lines or memory address registers. Features two 4-bit sections with independent active-low output enables.
74HC373 Octal Transparent D-Type Latch with 3-State Outputs
Octal transparent D-type latch with 3-state outputs. When Latch Enable (LE) is high, outputs follow inputs. When LE goes low, inputs are latched.
74HC374 Octal Edge-Triggered D-Type Flip-Flop with 3-State Outputs
Octal edge-triggered D-type flip-flop with 3-state true outputs. Data is transferred to outputs on the low-to-high transition of the clock pulse.

8-bit successive approximation analog-to-digital converter designed to interface directly with microprocessor buses via tri-state outputs and control strobes (~RD, ~WR).
CD4001B CMOS Quad 2-Input NOR Gate
Standard CMOS quad 2-input NOR gate with buffered outputs. Wide supply voltage range from 3V to 18V with high noise immunity.
CD4020B CMOS 14-Stage Binary Ripple Counter
14-stage binary ripple counter with master reset. Outputs available from stages 1 and 4 through 14 (stages 2 and 3 are not pinned out). Suitable for long-delay timers.
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.
CD4050B CMOS Hex Non-Inverting Buffer / Converter
Hex non-inverting buffer intended for logic-level conversion. Allowed to have input signal voltages up to 15V exceeding the supply voltage (e.g. 5V to 3.3V translation).
CD4069UB CMOS Hex Unbuffered Inverter
CMOS hex unbuffered inverter constructed with complementary MOS transistors. Single-stage design makes it ideal for linear oscillators, amplifiers, and audio synthesis.
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.
