MC14585BD

Comparators Overview

The MC14585BD is a 4-bit magnitude comparator constructed with complementary MOS (CMOS) enhancement mode devices. It operates within a supply voltage range of 3V to 18V and features active-high outputs for A<B, A=B, and A>B comparisons. The device utilizes a 16-pin SOIC package with dimensions of 10 x 4 x 1.5mm. It supports a wide operating temperature range from -55°C to +125°C. Static current consumption is specified at 20 µA. Propagation delay reaches 260ns at 15V with 50pF load. Output drive capability provides 4.2mA high and low currents.

Comparators Feature Summary

Comparators Procurement Notes

Verify component authenticity through authorized channels as the part status is obsolete. Confirm package integrity upon receipt, noting the 16-SOIC form factor. Check manufacturing date codes against relevant quality standards. Ensure storage conditions maintain moisture sensitivity level requirements prior to soldering. Validate pin alignment and lead finish compatibility with intended assembly processes.

Comparators Selection Notes

Select this component when 4-bit comparison functionality is required in a single integrated circuit. Consider the 16-SOIC package for surface mount applications needing moderate pin density. Evaluate the 3V to 18V supply range against system power constraints. Assess the -55°C to +125°C temperature rating for environmental suitability. Compare propagation delays against timing requirements of the target digital interface.
