What are the key features of CD74HC32EE4?
- Quad 2-input OR gate with 4 independent channels in a single 14-pin package, maximising logic density
- Wide supply voltage range of 2 V to 6 V enables seamless interfacing between 3.3 V and 5 V logic domains
- Propagation delay of 8 ns typical at 5 V VCC supports high-speed digital logic up to tens of MHz
- 25 mA output source/sink capability drives capacitive bus lines and LED indicators directly
- High-noise-immunity CMOS inputs (VIH = 3.5 V at 5 V) reject switching noise in noisy industrial environments
What is CD74HC32EE4 used for?
The CD74HC32EE4 is used in digital logic circuits where two or more binary signals must be combined with an OR function, such as interrupt flag merging in microcontroller systems and address-decode logic in embedded bus architectures. Its wide 2 V to 6 V supply range makes it a convenient level-bridging element between 3.3 V MCU outputs and 5 V peripheral inputs without additional level-shifter ICs. The 14-pin DIP package is also widely used in educational prototyping boards and hobbyist projects requiring quick breadboard assembly.

Frequently Asked Questions
How fast is the CD74HC32EE4, and does it work in a 20 MHz digital system?
The CD74HC32EE4 has a typical propagation delay of 8 ns at 5 V VCC, giving a maximum toggle frequency well above 60 MHz. It is therefore compatible with 20 MHz digital systems with substantial timing margin, making it suitable for glue-logic applications where the OR gate sits in the data or control path of a fast microcontroller or FPGA interface.
Can the CD74HC32EE4 interface directly between a 3.3 V MCU output and a 5 V peripheral input?
Yes. With a supply voltage range of 2 V to 6 V and CMOS-compatible input thresholds, the CD74HC32EE4 accepts 3.3 V logic-high signals when powered from 3.3 V, and its outputs swing to within millivolts of the rail when driving a 5 V peripheral if the device is powered from 5 V. For true bidirectional level translation, a dedicated level-shifter is still recommended.
How many output channels does the CD74HC32EE4 provide, and how much current can each drive?
The CD74HC32EE4 contains 4 independent 2-input OR gates, each capable of sourcing or sinking 25 mA. This is sufficient to drive a standard 5 mm LED through a current-limiting resistor directly from any output pin without an external buffer transistor, simplifying indicator circuits in prototyping and low-volume production designs.
Which package does CD74HC32EE4 use, and how does it compare to the surface-mount SOIC variant for hobbyist breadboard projects?
The CD74HC32EE4 ships in a 14-pin PDIP (plastic dual in-line) package with 2.54 mm (100 mil) pin pitch, which plugs directly into standard breadboards and through-hole PCB footprints. The equivalent SOIC variant requires an adapter board for breadboard use, so the E4 suffix PDIP version is preferred for rapid prototyping and classroom experiments despite its larger 19.4 mm body length.
