CD40101BD

Overview

The CD40101BD is a parity generator and checker belonging to the 4000/14000/40000 series of CMOS logic integrated circuits. It supports 9-bit data processing with complementary outputs. The device is housed in a ceramic dual in-line package (CDIP) featuring 14 pins. It operates within a temperature range of -55 °C to 125 °C and is designed for radiation-hardened applications.

Feature Summary

• Generates or checks parity for 9-bit data streams
• Provides complementary output signals
• Constructed using radiation-hardened CMOS technology
• Encapsulated in a hermetically sealed ceramic package

Applications

• Remote control circuits for lighting or other applications
• IF amplifier circuits with neutralization in radios
• Seven-segment display circuits for massagers
• Pulse-type light bulb energy-saving indicators

Procurement Notes

Verify the manufacturer origin, as Harris Corporation assets are now managed by Renesas Electronics. Confirm the specific suffix indicates the ceramic DIP package and radiation-hardened status. Ensure the component matches the required 4000-series CMOS specifications and operating temperature range for your design.

Selection Notes

Select this component when radiation tolerance and high-temperature operation are critical requirements. The 9-bit capacity suits specific data width needs without requiring multiple cascaded units. Verify that the complementary output configuration aligns with the downstream logic interface requirements.

Part Context

This part belongs to the extensive 4000-series CMOS logic family, known for wide voltage operation and low power consumption. The CD40101 variant specifically addresses data integrity through parity functions. The 'BD' suffix typically denotes the ceramic dual in-line package variant suitable for harsh environments.

Replacement Considerations

HCC40101BD is an equivalent part manufactured by STMicroelectronics or SGS-Ates, offering identical parity generation and checking functionality in a similar ceramic DIP package.
