What are the key features of CD4532BE?
- 8-input priority encoder outputting a 3-bit binary code for the highest-priority active input
- Wide supply voltage range from 3 V to 15 V enabling use in 5 V TTL-compatible and 12 V CMOS systems
- 16-pin DIP package for straightforward through-hole assembly and breadboard prototyping
What is CD4532BE used for?
The CD4532BE is used in keyboard scanning circuits, interrupt arbitration logic, and multi-sensor priority selection systems where 8 input signals must be encoded to a 3-bit binary output. It suits industrial control panels and embedded signal routing applications operating from 3 V to 15 V supplies. The 16-pin DIP form factor simplifies integration in through-hole prototyping and educational electronics platforms.

Frequently Asked Questions
How does CD4532BE determine which input has priority when multiple inputs are active simultaneously?
The CD4532BE resolves simultaneous active inputs by assigning priority to the highest-numbered input (input D7 has highest priority, D0 has lowest). The 3-bit binary output reflects the encoded address of the highest active input, and a Group Select output indicates at least one of the 8 inputs is active, enabling cascade of multiple 8-input encoders for larger priority logic.
What supply voltage range does CD4532BE support and which logic families can it interface with?
The CD4532BE operates from 3 V to 15 V, making it compatible with 5 V TTL-level logic, 5 V CMOS systems, and 12 V industrial control buses. At 5 V supply the propagation delay is typically 200 ns, and at 10 V it shortens further, giving designers flexibility to match system voltage and speed requirements in 16-pin DIP priority encoder applications.
In which embedded interrupt arbitration designs would CD4532BE be chosen over a software-based priority handler?
CD4532BE is preferred when hardware-level interrupt priority resolution must occur within 200 ns to 400 ns without burdening the microcontroller with polling overhead. A hardware 8-input priority encoder reduces interrupt latency in real-time control systems handling 8 concurrent event sources such as alarm inputs, limit switches, or sensor fault lines operating on 5 V or 12 V logic rails.
