CD4019BK3

Gates And Inverters - Multi-Function, Configurable Overview

The CD4019BK3 is a CMOS quad 2-input AND-OR gate manufactured by Harris Corporation. It features four independent logic circuits, each with two inputs, housed in a 16-lead Ceramic Flat Pack (CFP) package. The device operates within a supply voltage range of 3V to 18V and supports output drive currents of 6.8mA for both high and low states. It is designed for operation across an extended temperature range from -55°C to 125°C.

• Industrial control circuitry
• High-reliability computing modules

Gates And Inverters - Multi-Function, Configurable Procurement Notes

Verify the specific suffix 'K3' against the manufacturer's current datasheet SCHS029C to confirm pinout and electrical specifications match your design requirements. Ensure the supplier provides traceable documentation for the hermetic ceramic package, as this variant differs significantly from standard plastic DIP or SOIC versions in terms of handling and mounting procedures.

Gates And Inverters - Multi-Function, Configurable Selection Notes

Select this component when hermetic sealing and wide temperature tolerance are mandatory. The CFP package requires specific PCB footprint considerations compared to surface-mount alternatives. Confirm that the 3V to 18V supply range aligns with the system power rails, as lower voltage operation may impact switching speeds relative to higher voltage configurations.

Gates And Inverters - Multi-Function, Configurable Part Context

This part belongs to the Harris 4000/14000/40000 series of CMOS logic devices. The CD4019B type family includes various packages, with the BK3 designation specifically indicating the 16-lead hermetic dual-in-line ceramic flat pack configuration. This series is characterized by high noise immunity and low power consumption typical of CMOS technology.

Gates And Inverters - Multi-Function, Configurable Replacement Considerations

Cross-reference with other CD4019 variants such as CD4019BD3 or CD4019BC3 only if package compatibility is verified. Note that non-hermetic plastic packages do not offer the same environmental protection. Verify pin-to-pin compatibility before substitution.
