100336QI

Overview

The Fairchild Semiconductor 100336QI is a low-power ECL binary counter and shift register housed in a 28-pin PLCC package. It operates as a modulo-16 up/down counter or a 4-bit bidirectional shift register. The device features three Select inputs to determine operational mode. It belongs to the 100K series of synchronous, positive edge-triggered logic circuits designed for high-speed applications requiring low power consumption.

Feature Summary

• Configurable as either a modulo-16 up/down counter or a 4-bit bidirectional shift register
• Operates within the low-power ECL logic family for high-speed performance
• Utilizes three Select inputs to define functional mode

Applications

• High-speed digital counting systems
• Bidirectional data shifting applications
• ECL-based logic circuit designs

Procurement Notes

Verify the manufacturer origin, as Fairchild Semiconductor assets were acquired by ON Semiconductor. Confirm the specific suffix 'QI' corresponds to the 28-pin PLCC package with J-Lead configuration. Ensure compatibility with existing ECL voltage levels and signal timing requirements before integration into new designs.

Selection Notes

Select this component when a synchronous, low-power ECL solution is required for modulo-16 counting or 4-bit bidirectional shifting. The 28-pin PLCC package suits surface-mount assembly processes. Consider the positive edge-triggered nature and the specific control input requirements for mode selection during system architecture planning.

Part Context

This part belongs to the Fairchild 100K series of ECL logic devices. The 100336 variant specifically provides dual functionality as a counter and shift register. The 'QI' designation identifies the plastic quad flat pack (PLCC) package variant with J-leads, distinguishing it from other package options like the QIX suffix.

Replacement Considerations

Check for equivalents within the ON Semiconductor portfolio following the Fairchild acquisition. Verify pinout and electrical characteristics against other 100K series ECL counters if sourcing from alternative manufacturers.
