MC14557BCPG

Shift Registers Overview

The MC14557BCPG is a CMOS counter shift register from the MC14 series, manufactured by onsemi. It features a serial-to-serial counting architecture with a 64-bit capacity and supports seven internal circuits. The device operates within a supply voltage range of 3 V to 18 V and functions reliably across an extended temperature range from -55 °C to +125 °C. Propagation delays are specified at 600 ns, 260 ns, and 180 ns depending on conditions. It utilizes a 16-pin PDIP package for through-hole mounting.

Shift Registers Feature Summary

• Serial-to-serial counting architecture for sequential data processing
• Extended industrial temperature operation capability
• Wide single-supply voltage compatibility

Shift Registers Applications

• Sequential logic control systems
• Data shifting operations in digital circuits
• Counter applications requiring serial input/output

Shift Registers Procurement Notes

Verify component authenticity against official onsemi documentation due to discontinued status. Confirm package integrity and pin alignment for the 16-PDIP form factor. Ensure compliance with specific project requirements regarding legacy CMOS logic families. Cross-reference datasheet revisions to confirm electrical characteristics match design specifications before integration.

Shift Registers Selection Notes

Select this component for designs requiring robust serial-to-serial counting with wide voltage tolerance. Consider the 64-bit depth and serial interface constraints when planning system timing. Evaluate the PDIP package suitability for through-hole assembly processes. Verify that the propagation delay characteristics meet the maximum clock frequency requirements of the target application circuit.

Shift Registers Part Context
