What are the key features of CD74HC32ME4?
- Quad 2-input OR gate provides 4 independent logic gates in a single 14-pin SOIC package, reducing component count and board space in combinational logic designs
- High-speed CMOS HC-family technology delivers fast propagation delays with low static power consumption, suitable for 2 V to 6 V systems
- 50 pF rated load capacitance and 4 mA output sink current ensure reliable signal drive across moderate fanout configurations without external buffers
- RoHS-compliant lead-free e4 finish and plastic SOIC-14 packaging meet modern environmental regulations for commercial and industrial PCB assembly
What is CD74HC32ME4 used for?
The CD74HC32ME4 is used in digital logic designs requiring OR gate combinational logic, such as interrupt signal merging, address decoding, and enable-signal gating in microcontroller and FPGA peripheral circuits. Its HC-family CMOS technology makes it compatible with 3.3 V and 5 V logic levels, bridging signal domains in mixed-voltage systems common in embedded and industrial control boards. The quad configuration reduces IC count in glue logic applications, making it a standard component in prototyping, test equipment, and production PCBs that need basic Boolean logic functions.

Frequently Asked Questions
How many independent OR gate functions does the CD74HC32ME4 provide, and how many inputs does each gate have?
The CD74HC32ME4 contains 4 independent 2-input OR gates in a single 14-pin SOIC package. Each gate performs a standard Boolean OR operation, combining two digital inputs into one output, which covers the majority of combinational logic gating requirements in microcontroller glue logic, signal routing, and interrupt aggregation circuits.
What output drive capability does the CD74HC32ME4 offer, and is it sufficient for standard CMOS fanout requirements?
Each output can sink up to 4 mA and is rated for a 50 pF load capacitance, which satisfies typical CMOS fanout of 10 HC-family inputs or a moderate number of 3.3 V CMOS inputs. For higher fanout or long PCB traces, a buffer such as a 74HC244 should be added downstream to avoid degraded propagation delay and signal integrity.
Is the CD74HC32ME4 compatible with both 3.3 V and 5 V logic systems?
Yes. The HC-family operating supply range spans from 2 V to 6 V, allowing the CD74HC32ME4 to function correctly in 3.3 V and 5 V systems. Input thresholds scale with VCC, so the device accepts 5 V logic inputs when powered at 5 V and 3.3 V logic inputs when powered at 3.3 V, with no voltage translation circuitry required for single-voltage designs.
What physical package does the CD74HC32ME4 use, and how does it compare to DIP alternatives for production PCBs?
The CD74HC32ME4 uses a 14-pin SOIC (R-PDSO-G14) package with 1.27 mm pin pitch, which occupies roughly 60% less PCB area than an equivalent DIP-14 through-hole package. The surface-mount SOIC format is preferred in modern automated PCB assembly lines for its compatibility with reflow soldering and pick-and-place equipment, making it a better production choice than through-hole DIP alternatives.
