What are the key features of SN74LVC02AD?
- Four independent 2-input NOR gates in a single 14-pin SOIC package enabling efficient multi-signal logic operations with minimal board space
- Wide 1.65V to 3.6V operating voltage range from the LVC (Low Voltage CMOS) family supporting 1.8V, 2.5V, and 3.3V logic systems natively
- 24mA output drive current (I_OL) providing sufficient sink capability to drive LEDs, bus lines, and moderate capacitive loads directly
- 50pF rated load capacitance with fast switching speeds and low propagation delay typical of the LVC family for high-speed logic applications
- 5V input-tolerant I/O allowing direct connection to 5V logic signals while operating from a 3.3V or lower supply voltage
What is SN74LVC02AD used for?
The SN74LVC02AD quad NOR gate is extensively used in digital logic design for implementing combinational logic functions such as NAND, NOT, and AND operations using NOR-gate equivalents. It serves as a fundamental building block in microcontroller interface circuits, FPGA peripheral glue logic, and bus control systems operating at 3.3V or lower supply voltages. The device is also used in signal conditioning, reset circuit design, and enabling/disabling signal paths in embedded systems and communication equipment.

Frequently Asked Questions
What is the operating voltage range of the SN74LVC02AD?
The SN74LVC02AD operates from a supply voltage (VCC) of 1.65V to 3.6V, making it fully compatible with 1.8V, 2.5V, and 3.3V digital systems. The LVC family also features 5V-tolerant inputs, allowing the device to accept 5V logic input signals while operating from a lower supply voltage, simplifying mixed-voltage system design.
How many NOR gates are included in the SN74LVC02AD and what is the input configuration?
The SN74LVC02AD contains four independent 2-input NOR gates within a single 14-pin SOIC package. Each gate has two separate inputs and one output, providing four complete NOR logic functions. This quad configuration reduces component count and PCB space compared to using discrete logic gates, which is particularly valuable in high-density board designs.
What is the output drive capability of the SN74LVC02AD?
The SN74LVC02AD can sink up to 24mA (I_OL) in the low output state, making it capable of directly driving small loads such as LEDs with appropriate current-limiting resistors, as well as bus lines with multiple receiver loads. The rated load capacitance is 50pF, and the device maintains specified switching characteristics within this capacitive loading limit for reliable high-speed operation.
Is the SN74LVC02AD compatible with 5V TTL logic inputs?
Yes, the SN74LVC02AD features 5V-tolerant inputs, meaning it can safely accept input voltage levels up to 5.5V even when powered from a 1.65V to 3.6V supply. This makes it ideal for interfacing between 5V TTL or CMOS logic and modern 3.3V or lower-voltage microcontrollers and FPGAs without requiring additional level-shifting circuits or protection resistors.
What package does the SN74LVC02AD use and is it RoHS compliant?
The SN74LVC02AD is packaged in a 14-pin SOIC (Small Outline Integrated Circuit) with a standard 3.9mm body width and 1.27mm pin pitch, suitable for automated reflow soldering. The device is RoHS compliant and lead-free as indicated by its Pb-free code, meeting environmental requirements for EU RoHS directive compliance in consumer, industrial, and telecommunications applications.
