CD4042BM

Latches Overview

The CD4042BM is a quad D-type latch manufactured by Harris Corporation, belonging to the 4000/14000/40000 series of CMOS logic devices. It integrates four independent high-level triggered latches within a single package, providing complementary outputs for each bit. The device operates on a supply voltage range of 3V to 18V and supports an operating temperature range from -55°C to +125°C. It utilizes a 16-pin plastic flatpack (FP-16) surface-mount package. Key electrical characteristics include a maximum low-level output current of 0.00036 A and a load capacitance of 50 pF. The component is not RoHS compliant.

Latches Feature Summary

• Integrates four independent D-type latches with high-level triggering capability
• Provides both non-inverting and inverting complementary outputs for data storage
• Operates across a wide supply voltage range suitable for various digital logic levels
• Designed for extended industrial temperature environments

Latches Applications

• Data storage and buffering in digital systems
• Parallel-to-serial conversion circuits
• Shift register implementations
• Memory address latching

Latches Procurement Notes

Verify compliance requirements as this specific part number is listed as non-RoHS compliant. Confirm the package type matches the design footprint, as variations exist between ceramic and plastic packages within the CD4042 family. Check manufacturer documentation for lead times and availability status, as older CMOS components may have limited production runs or be subject to obsolescence notices.

Latches Selection Notes

Select this component when a quad latch configuration is required for high-level triggered data retention. Ensure the application voltage falls within the 3V to 18V range. Consider the 16-pin flatpack package constraints for PCB layout. Verify that the complementary output requirement aligns with the downstream circuit design needs.

Latches Part Context

The CD4042BM is part of the extensive CD4000B series of CMOS logic integrated circuits originally developed by Harris Semiconductor. This series is known for its wide power supply range and compatibility with standard TTL logic levels. The CD4042 specifically addresses the need for multi-bit data storage elements in complex digital designs without requiring multiple discrete latch ICs.
