MC14532BCPG

Overview

The MC14532BCPG is an 8-bit priority encoder manufactured by onsemi, utilizing CMOS enhancement mode technology. It accepts eight data inputs (D0–D7) and an enable input (Ein), providing a binary address for the active input with the highest priority. The device features five outputs: three address lines (Q0–Q2), a group select output (GS), and an enable output (Eout). It operates within a supply voltage range of 3.0 Vdc to 18 Vdc and supports an ambient temperature range from -55 °C to +125 °C. Propagation delay times vary based on voltage; at 5 V, delays range from 600 ns maximum, while at 15 V, they reduce to 220 ns maximum.

Feature Summary

• Provides binary addressing for the highest priority active input among eight data lines
• Includes diode protection on all inputs to guard against high static voltages or electric fields
• Capable of driving two Low-Power TTL loads or one Low-Power Schottky TTL load across the rated temperature range

Applications

• Digital-to-Analog conversion circuits
• Analog-to-Digital conversion systems
• Keyboard encoding applications

Procurement Notes

Verify that the ordering suffix 'G' corresponds to the Pb-Free package specification as defined in the manufacturer's documentation. Confirm the PDIP-16 package type matches the required board layout. Ensure compatibility with the specified logic family requirements before finalizing procurement orders.

Selection Notes

Select this component when an 8-bit priority encoding function is required within a CMOS logic design. Consider the wide operating voltage range suitable for various digital systems. Evaluate the propagation delay specifications against system timing requirements, noting performance variations across different supply voltages and load conditions.

Part Context

This part belongs to the MC14532B series of priority encoders produced by onsemi. The series includes variants such as MC14532BCP and MC14532BDG, differing primarily in packaging options like PDIP-16 and SOIC-16. All variants share the same core logical functionality and electrical characteristics defined in the MC14532B datasheet.

FAQ

What is the primary function of the GS output?

The Group Select (GS) output indicates whether any of the data inputs are active. It goes high when the enable input is active and at least one data input is asserted.

How does the Eout signal behave?

The Enable Output (Eout) goes high when the enable input (Ein) is low, indicating that the encoder is disabled. When Ein is high, Eout goes low.
