100336SCX

Overview

The onsemi 100336SCX is a low-power 4-stage counter and shift register housed in a 24-lead Small Outline Integrated Circuit (SOIC) package. It operates as a modulo-16 up/down counter or a bidirectional shift register, controlled by three Select inputs. The device features asynchronous Master Reset, synchronous clear, and complement functions. It supports cascading via Count Enable inputs and includes dual Terminal Count outputs for multistage linking. Operating conditions range from −4.2V to −5.7V supply voltage, with commercial temperature support from 0°C to +85°C.

Feature Summary

• Supports both modulo-16 counting and bidirectional shifting modes via selectable control inputs.
• Includes asynchronous Master Reset and synchronous clear/complement capabilities for flexible state management.
• Features dedicated Count Enable inputs to facilitate easy cascading of multiple stages.
• Integrates internal pull-down resistors on all inputs to ensure defined logic states.

Applications

• Multistage binary counters
• Bidirectional shift registers
• Frequency dividers

Procurement Notes

Verify the specific ordering suffix 'X' indicates tape and reel packaging rather than standard tube delivery. Confirm that the SC designation corresponds to the 24-lead SOIC package variant. Ensure the application environment remains within the specified commercial temperature limits of 0°C to +85°C. Validate power supply stability between −4.2V and −5.7V to maintain electrical characteristics.

Selection Notes

Select this component when a low-power ECL-compatible counter/shift register is required in a surface-mount format. The 100336 offers pin compatibility with the 100136 series while providing reduced power consumption. Consider the industrial grade version if operation below 0°C is necessary. The SOIC package is suitable for high-density PCB layouts requiring standard footprint dimensions.

Part Context

This device belongs to the 100336 family of low-power 4-stage counters manufactured originally by Fairchild Semiconductor and now distributed by onsemi. The family includes variants such as the PDIP and PLCC packages. The 100336 serves as a functional replacement for older 100136 designs, maintaining interface compatibility while improving power efficiency for modern digital logic applications.

Replacement Considerations

The 100336 is functionally compatible with the 100136. Verify package differences when substituting DIP or PLCC versions for the SOIC variant.
