CD40101BK3

Overview

The CD40101BK3 is a CMOS parity generator and checker belonging to the 4000/14000/40000 series. It features nine-bit data input capability with complementary outputs. The device operates within a supply voltage range of 5 V to 15 V and supports an operating temperature range from -55 °C to 125 °C. It utilizes a CDFP14 ceramic flatpack package containing 14 terminals, designed for radiation-hardened applications.

Feature Summary

• Performs odd or even parity generation and checking functions
• Includes an inhibit control feature
• Provides complementary output signals

Applications

• Data transmission error detection systems
• Digital memory storage parity verification
• Radiation-tolerant computing environments

Procurement Notes

Verify the specific suffix BK3 against manufacturer documentation to confirm the ceramic flatpack configuration and radiation-hardening status. Ensure compatibility with existing system voltage levels and thermal requirements before procurement.

Selection Notes

Select this component when a radiation-hardened parity solution is required for high-temperature environments. The complementary output structure simplifies interface design compared to single-ended alternatives. Verify that the nine-bit capacity aligns with the target data bus width.

Part Context

This part belongs to the Harris Corporation 4000-series logic family, known for wide voltage operation and robust performance in harsh conditions. The CD40101 variant specifically addresses data integrity needs through hardware-based parity calculation, distinct from buffer or flip-flop logic elements.
