MC14532BDG

Overview

The MC14532BDG is an 8-bit priority encoder manufactured by onsemi, belonging to the MC14532B series. It converts eight active-high input lines into a three-bit binary code representing the highest-order active input. The device operates within a supply voltage range of 3V to 18V and supports dual power supplies. It features low static power consumption typical of CMOS technology and provides high noise immunity. The component is housed in a 16-SOIC surface-mount package with a wide operating temperature range from -55°C to +125°C.

Feature Summary

• Converts eight input signals into a three-bit binary output based on priority
• Operates reliably across a wide voltage range of 3V to 18V
• Designed for industrial environments with extended temperature stability

Applications

• Interrupt controller systems requiring priority handling
• Keyboard encoding circuits
• Data acquisition systems

Procurement Notes

Verify the specific suffix BDG indicates the SOIC-16 tube packaging configuration distinct from other variants like BDR2G which uses tape and reel. Confirm RoHS compliance status as per current manufacturer declarations. Ensure the ordering part number matches the exact logic family requirements for your design. Cross-reference the datasheet revision history for any pinout or electrical characteristic updates before finalizing procurement.

Selection Notes

Select this component when an 8-to-3 priority encoding function is required in a compact surface-mount format. The MC14532BDG is suitable for designs needing robust performance across extreme temperatures. Compare propagation delay specifications against system timing constraints at the intended operating voltage. Consider the 16-pin SOIC footprint availability during PCB layout planning to ensure adequate spacing for thermal management.

Part Context

This part belongs to the MC14532B family of priority encoders produced by onsemi. It serves as a standard solution for converting multiple input lines into encoded binary outputs. The device complements other logic components such as decoders and multiplexers within the same product line. It is widely used in embedded systems where reliable signal prioritization is critical for proper data processing and control.
