MC14557BDWR2

Shift Registers Overview

The MC14557BDWR2 is a static clocked serial shift register from the onsemi 4000B series, housed in a 16-SOIC surface-mount package. It contains one 64-bit element capable of variable length programming between 1 and 64 bits. The device operates on a supply voltage range of 3V to 18V and supports a wide operating temperature range from -55°C to 125°C. Outputs are complementary, providing both true and inverted signals for flexible interfacing.

Shift Registers Feature Summary

• Features a single 64-bit shift register with programmable bit length capability ranging from 1 to 64 bits.
• Provides complementary output stages delivering both true and inverted logic signals simultaneously.

Shift Registers Applications

• Serial-to-parallel data conversion circuits
• Variable-length digital delay line implementations
• General-purpose sequential logic control systems

Shift Registers Procurement Notes

Verify RoHS compliance status carefully as older manufacturing runs may differ from current specifications. Confirm package dimensions against the 16-SOIC standard before PCB layout finalization. Ensure supply chain sources provide valid traceability documentation for components intended for high-reliability applications.

Shift Registers Selection Notes

Select this component when a single integrated solution for long serial shifts is required without cascading multiple devices. The wide voltage tolerance allows operation in diverse power environments. Verify that the complementary output requirement matches the downstream logic interface needs.

Shift Registers Part Context
