4015A/BEA

Overview

The CD4556BE is a dual 4-bit shift register from the 4000/14000/40000 series, manufactured by Rochester Electronics. It features inverted outputs and operates within a supply voltage range of 3 V to 18 V, with a nominal rating of 5 V. The device supports an operating temperature range from -55 °C to 125 °C. Packaged in a 16-pin PDIP (R-PDIP-T16) format, it contains two functional units within a single plastic epoxy enclosure. This component is designed for commercial applications requiring reliable serial-to-parallel data conversion capabilities.

Feature Summary

• Dual independent 4-bit shift register functionality within a single package
• Inverted output configuration for signal processing flexibility
• Wide operating temperature range suitable for harsh environments
• Robust power supply tolerance across 3 V to 18 V

Applications

• Serial-to-parallel data conversion systems
• Digital signal processing interfaces

Procurement Notes

Verify the specific manufacturer lot code and date code upon receipt, as Rochester Electronics sources components from various original manufacturers. Confirm that the PDIP-16 package matches your PCB footprint requirements. Ensure the operating environment stays within the specified -55 °C to 125 °C range to maintain performance integrity. Check for any specific handling instructions related to electrostatic discharge protection during installation.

Selection Notes

Select this component when dual 4-bit shift registers are required in a compact DIP package. Consider the inverted output polarity if it aligns with your logic design needs. Verify that the 3 V to 18 V supply range fits your system's power architecture. Ensure the through-hole PDIP-16 package is compatible with your assembly process. Evaluate the wide temperature range against your environmental constraints.

Part Context

This part belongs to the extensive 4000/14000/40000 series of CMOS logic devices. Rochester Electronics provides these components as a continuous source for lifecycle management. The CD4556BE serves as a replacement or alternative for legacy designs requiring dual shift registers.
