Each of the four latches is set and reset by active-high inputs, with a common output enable (OE) pin that places all outputs in a high-impedance state when low. This IC is ideal for digital memory and bus-oriented applications in hobbyist and educational projects.\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eLogic family: CMOS\u003c\/li\u003e\n\u003cli\u003eSupply voltage: 3V to 15V DC\u003c\/li\u003e\n\u003cli\u003eNumber of latches: 4 (quad)\u003c\/li\u003e\n\u003cli\u003eLatch type: NOR R-S (Set\/Reset)\u003c\/li\u003e\n\u003cli\u003eOutput type: Tri-state (3-state) with common Output Enable (OE)\u003c\/li\u003e\n\u003cli\u003eInput logic: Active-high for Set (S) and Reset (R)\u003c\/li\u003e\n\u003cli\u003ePackage: DIP-16 (Dual In-line Package, 16 pins)\u003c\/li\u003e\n\u003cli\u003eOperating temperature: -55°C to +125°C\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatible with\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eArduino (Uno, Mega, Nano, etc.)\u003c\/li\u003e\n\u003cli\u003eESP32 and ESP8266\u003c\/li\u003e\n\u003cli\u003eRaspberry Pi (via level shifting)\u003c\/li\u003e\n\u003cli\u003eSTM32 microcontrollers\u003c\/li\u003e\n\u003cli\u003eAny 3V–15V logic system\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhat you can build with it\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDigital memory register for storing button states or sensor flags\u003c\/li\u003e\n\u003cli\u003eBus-controlled output latch for multiplexing multiple devices on shared data lines\u003c\/li\u003e\n\u003cli\u003eSimple state machine for educational logic design projects\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eBuilt and Backed by Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery CD4043 you buy from Compoden comes with a free AI build companion — delivered via QR code, email, or WhatsApp — that helps you wire and program this IC into a working project.

When the Output Enable (OE) pin is low, all outputs go to Hi-Z, effectively disconnecting them from the circuit bus. This allows multiple devices to share the same data lines.\n\u003c\/p\u003e\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eHow do I set and reset a latch on the CD4043?\u003c\/summary\u003e\n\u003cp\u003eEach latch has a Set (S) and Reset (R) input. Applying a logic high to the S input sets the output high. Applying a logic high to the R input resets the output low.
