MC14585BDR2G

Overview

The MC14585BDR2G is a 4-bit magnitude comparator constructed with complementary MOS (CMOS) enhancement mode devices. It features eight comparing inputs and provides three active-high outputs indicating A < B, A = B, and A > B relationships. The device operates within a supply voltage range of 3 V to 18 V and draws a maximum power supply current of 5 uA. Output drive capabilities include high-level output currents up to -8.8 mA and low-level output currents up to 8.8 mA. Propagation delays vary between 130 ns and 430 ns depending on conditions. It functions reliably across an extended temperature range from -55 °C to +125 °C.

Feature Summary

• Performs four-bit digital magnitude comparison with dedicated outputs for less than, equal to, and greater than conditions
• Utilizes CMOS enhancement mode technology for low static power consumption
• Provides active-high logic outputs compatible with standard digital interfaces
• Supports wide operating voltage ranges suitable for diverse system requirements

Applications

• Digital signal processing systems requiring amplitude comparison
• Control logic circuits for automated measurement equipment
