CDP1882D

Overview

The CDP1882D is a 6-bit latch and decoder manufactured by Harris Corporation. It functions as a 1 x 4:4 decoder for digital logic applications. The component operates within an ambient temperature range of -40°C to 85°C. It features output current capabilities of 2.3mA high and 3.2mA low. The device is housed in an 18-pin CDIP package with a width of 0.300 inches (7.62mm).

Feature Summary

• Integrates 6-bit latching capability with decoding functionality.
• Provides 1-to-4 channel decoding architecture.
• Supports standard TTL-compatible output drive levels.

Applications

• Digital logic interface circuits
• Memory address decoding systems
• Control signal routing

Procurement Notes

Verify the specific suffix designation against official Harris Semiconductor documentation to confirm exact electrical characteristics and package variant. Ensure the operating temperature range meets system requirements. Confirm pinout compatibility with existing PCB layouts before procurement.

Selection Notes

Select this component when a combined latch and decoder solution is required for 1-of-4 addressing. Consider the 18-pin CDIP package constraints for board space. Evaluate the output current specifications against load requirements to ensure signal integrity.

Part Context

This part belongs to the Harris CDP1882 family, which includes variants like the CDP1882CE. These components are designed for memory interface and control applications requiring reliable decoding and data retention in industrial environments.

Replacement Considerations

Check for direct substitutes such as the CDP1882CE, ensuring pinout and electrical parameters match. Verify functional equivalence with other 1x4 decoders from different manufacturers if supply chain constraints exist.
