CD4013BM

Overview

The CD4013BM is a dual D-type flip-flop integrated circuit manufactured by Texas Instruments, belonging to the 4000B series of CMOS logic devices. It contains two independent positive-edge-triggered D flip-flops within a single package, each featuring complementary Q and /Q outputs. The device supports a wide supply voltage range of 3V to 18V and operates across an extended temperature range of -55°C to 125°C. It utilizes a 14-pin ceramic flat pack (CDFP14) or similar hermetic package configuration, ensuring robust performance in industrial environments with low power consumption and high noise immunity typical of CMOS technology.

Feature Summary

• Dual independent positive-edge-triggered D flip-flops with complementary outputs
• Wide operating voltage range supporting 3V to 18V supply rails
• Extended industrial temperature rating from -55°C to 125°C
• Hermetic ceramic packaging for enhanced environmental reliability

Applications

• Industrial control systems requiring reliable data storage
• Military and aerospace electronic circuits demanding high reliability
• Instrumentation systems utilizing wide-temperature operation

Procurement Notes

Verify the specific package variant, as the CD4013BM designation may correspond to different physical packages such as the CDFP14 ceramic flat pack depending on the manufacturer's revision history. Confirm RoHS compliance status if required for modern assembly processes, noting that older ceramic versions may have different regulatory classifications. Ensure the supplier provides traceability documentation for military or aerospace applications where the W/883 suffix variants are often specified. Cross-reference the ordering prefix with the latest Texas Instruments datasheet to confirm pinout compatibility and electrical specifications before finalizing procurement orders.

Selection Notes

Select the CD4013BM when a dual D-type flip-flop solution is required with hermetic sealing for harsh environments. This component is suitable for designs necessitating a wide voltage range and extended temperature operation without the need for additional level shifting. Consider the physical footprint constraints of the ceramic flat pack versus surface-mount alternatives like the SOIC variants if PCB space is limited. Evaluate the trade-off between the higher cost of hermetic packages and the reliability benefits for long-life or safety-critical applications compared to standard plastic封装 options.
