MC14549BCPG

Shift Registers Overview

The MC14549BCPG is a CMOS 8-bit successive approximation register manufactured by onsemi. It operates within a supply voltage range of 3 V to 18 V and supports a maximum input frequency of 3 MHz. The device features an asynchronous reset function and utilizes a 16-pin PDIP package for through-hole mounting. It functions as a single circuit component with push-pull outputs, designed for industrial temperature ranges from -55 °C to +125 °C.

Shift Registers Feature Summary

• Implements 8-bit successive approximation logic for data conversion applications
• Supports high-speed operation with a maximum input frequency of 3 MHz
• Provides asynchronous reset capability for immediate state initialization

Shift Registers Applications

• Analog-to-digital converter (ADC) front-end stages
• Digital potentiometer control circuits
• Programmable gain amplifier interfaces

Shift Registers Procurement Notes

Verify the specific suffix 'CPG' against the official datasheet to confirm the PDIP-16 package type and lead-free status. Ensure the operating environment remains within the specified -55 °C to +125 °C range. Confirm that the 3 V to 18 V supply voltage aligns with system requirements before integration.

Shift Registers Selection Notes

Select this component when an 8-bit resolution is required for successive approximation tasks. The wide supply voltage range allows compatibility with various logic families. The PDIP package is suitable for prototyping or applications requiring through-hole assembly rather than surface mount technology.

Shift Registers Part Context

This part belongs to the MC14549B series of CMOS logic devices. It is distinct from other MC14xxx series counters and timers by its specific successive approximation architecture. The device is designed for monolithic integration of digital sampling functions within mixed-signal systems.
