Key Features
- 4 independent 2-input OR gates in a single 14-pin PDIP package for dense combinational logic implementations
- AC CMOS family delivers faster switching speeds than standard HC logic while maintaining low power consumption
- 24 mA maximum output low current (I_OL) enables direct driving of multiple CMOS and TTL-compatible inputs
- 50 pF load capacitance rating supports typical PCB trace and fan-out loads without propagation delay derating
- RoHS-compliant lead-free 14-pin PDIP package ideal for through-hole prototyping and legacy board repair
Applications
The CD74AC32EE4 is used in combinational logic circuits requiring OR operations, including signal multiplexing, interrupt aggregation, and enable-logic networks in microcontroller and FPGA peripheral designs. Its 24 mA output drive and AC-family speed make it suitable for bus interface logic and clock-enable circuits that need to drive multiple downstream inputs reliably. The 14-pin PDIP package supports rapid prototyping on breadboards and repair of older through-hole PCB assemblies.

Frequently Asked Questions
How does the AC family speed of CD74AC32EE4 compare to HC-family OR gates in time-critical logic paths?
The CD74AC32EE4 belongs to the AC (Advanced CMOS) logic family, which typically offers propagation delays of 5 ns to 8 ns at 5 V supply, roughly 2 to 3 times faster than the equivalent HC-family part at the same voltage. This speed advantage matters in clock distribution, interrupt aggregation, and bus arbitration circuits where tight setup and hold margins must be maintained.
Can the CD74AC32EE4 drive multiple CMOS inputs directly from a single output?
Yes, the CD74AC32EE4 output can source or sink up to 24 mA, which is substantially higher than the 4 mA to 8 mA of standard HC-family outputs. This allows a single CD74AC32EE4 output to directly drive 4 to 8 CMOS gate inputs in parallel while remaining within the 50 pF load capacitance rating for full-speed operation.
For a breadboard prototype that requires an OR gate at 3.3 V logic levels, is CD74AC32EE4 compatible?
The CD74AC32EE4 is specified to operate over a supply range of 1.5 V to 5.5 V, so it can run at 3.3 V and accept logic-HIGH inputs from 3.3 V microcontroller or FPGA GPIO pins. However, input-level thresholds shift with supply voltage, so designers should verify that the 3.3 V HIGH level exceeds the VIH threshold at that supply for reliable switching.
When should a designer choose the through-hole CD74AC32EE4 over a surface-mount AC-family OR gate?
The CD74AC32EE4 in a 14-pin PDIP through-hole package is the preferred choice for breadboard prototyping, university lab experiments, and through-hole PCB designs where hand-soldering or socketed DIP placement is required. Surface-mount versions in SOIC-14 or TSSOP-14 offer a smaller footprint for high-volume production boards but cannot be inserted into standard 0.1-inch pitch breadboard sockets.
