MC14585BDG

The MC14585BDG from On Semiconductor is a 4-bit magnitude comparator integrated circuit. Constructed with complementary MOS (CMOS) enhancement mode devices, it compares two 4-bit words (A and B) and indicates if they are less than, equal to, or greater than each other via dedicated outputs. This device features eight comparing inputs and three cascading inputs, allowing for expansion to compare words longer than 4 bits.

Key electrical specifications include a wide supply voltage range from 3V to 18V and a low quiescent current of 20 µA. The operating temperature range is -55°C to +125°C, making it suitable for various environmental conditions. The maximum propagation delay is 260ns at 15V with a 50pF load.

Packaged in a 16-SOIC (0.154", 3.90mm Width) surface mount package, the MC14585BDG is designed for standard PCB assembly. It offers diode protection on all inputs and is capable of driving two low-power TTL loads or one low-power Schottky TTL load. This device is also Pb-free and RoHS compliant.

Applications for the MC14585BDG include logic functions in CPUs, correction and detection in instrumentation, and use as a comparator in testers, converters, and control systems. Its expandable nature makes it versatile for systems requiring multi-bit comparisons.
