CD4027BD3

Overview

The CD4027BD3 is a dual J-K flip-flop from the Harris 4000/14000/40000 series, housed in a 16-lead ceramic DIP package. It features positive edge triggering and complementary outputs. The device operates within a supply voltage range of 3V to 18V, with a maximum clock frequency of 24 MHz. It supports static operation, retaining state indefinitely regardless of clock level. The component is rated for an operating temperature range of -55°C to 125°C and has a load capacitance of 50 pF.

Feature Summary

• Dual J-K flip-flop configuration with set-reset capability
• Static operation retains state indefinitely with clock level either high or low
• Positive edge triggered with complementary outputs

Applications

• Radio equipment
• Telex systems
• Telephones

Procurement Notes

Verify the specific suffix 'BD3' against the manufacturer's official documentation to confirm package type and material specifications. Ensure compliance with RoHS requirements as indicated by the 'non-compliant' status in some databases. Confirm availability through authorized distributors for Harris Semiconductor legacy components.

Selection Notes

Select this component for applications requiring dual J-K flip-flops with ceramic packaging and wide temperature tolerance. Consider the 24 MHz maximum clock frequency and 3V-18V supply range when designing circuits. Verify that the complementary output polarity meets system logic requirements.

Part Context

This part belongs to the Harris 4000/14000/40000 CMOS logic series. It is functionally similar to other dual J-K flip-flops in the family but distinguished by its ceramic DIP-16 package and specific thermal ratings. It serves as a digital storage element in sequential logic circuits.
