MC14532BDR2

Overview

The MC14532BDR2 is an 8-bit priority encoder constructed with CMOS enhancement mode devices. It accepts eight data inputs (D0 through D7) and provides a binary address for the active input with the highest priority. The device features three address outputs (Q0-Q2), a group select output (GS), and an enable output (Eout). It operates on a dual power supply ranging from 3.0 Vdc to 18 Vdc. The component includes diode protection on all inputs and is capable of driving two low-power TTL loads or one low-power Schottky TTL load over the rated temperature range.

Feature Summary

• Provides a binary address for the active input with the highest priority among eight data inputs
• Includes diode protection on all inputs to guard against damage from high static voltages or electric fields
• Capable of driving two low-power TTL loads or one low-power Schottky TTL load over the rated temperature range

Applications

• Digital to Analog conversion circuits
• Analog to Digital conversion circuits
• Cascaded configurations for 4-bit output generation

Procurement Notes

Verify that the ordering suffix DR2 corresponds to the SOIC-16 package in tape and reel shipping format. Confirm the specific manufacturer part number matches the required logic family and pin configuration. Ensure compatibility with the intended voltage range and temperature specifications before finalizing procurement orders.

Selection Notes

Select this component when an 8-bit priority encoding function is required within a CMOS logic design. Consider its ability to interface directly with low-power TTL loads if mixed-logic systems are utilized. Evaluate the operating voltage requirements against the specified 3.0 Vdc to 18 Vdc range to ensure proper functionality under varying supply conditions.
