CD14538BK3

Multivibrators Overview

The CD14538BK3 is a dual precision monostable multivibrator manufactured by Harris Corporation. It operates within a supply voltage range of 2V to 6V and supports a maximum frequency of 38MHz. The device is housed in a 16-DIP package with a pitch of 0.300 inches (7.62mm). It functions as a single circuit unit with CMOS input and output characteristics. The component is rated for an operating temperature range from -55°C to 125°C and utilizes through-hole mounting technology.

Multivibrators Feature Summary

• Dual precision monostable multivibrator configuration
• CMOS logic input and output compatibility
• Wide industrial temperature rating capability

Multivibrators Applications

• Timing pulse generation circuits
• Frequency division applications
• Waveform shaping systems

Multivibrators Procurement Notes

Verify the manufacturer designation, as this part number is associated with Harris Corporation but may be distributed by other entities such as Rochester Electronics LLC or Intersil. Confirm the specific suffix 'BK3' indicates the ceramic flatpack package variant rather than the standard DIP version found in general listings. Ensure compliance with EAR99 export classification requirements before procurement.

Multivibrators Selection Notes

Select this component when a dual precision monostable multivibrator with wide temperature tolerance is required. The choice depends on the need for CMOS interface compatibility and the specific physical form factor constraints of the target PCB layout. Verify that the 16-pin footprint matches the design schematic, distinguishing between the DIP and CDFP package options available under similar part numbers.

Multivibrators Part Context

This component belongs to the 4000/14000/40000 series of CMOS logic devices produced by Harris Corporation. It shares functional similarities with other monostable multivibrators in the family, such as the CD14538BEX. The device represents legacy semiconductor manufacturing from Harris, which was later acquired by Intersil and subsequently Renesas.

Multivibrators Replacement Considerations

Public confirmed substitute part numbers include CD14538B and HEF4538B.
