SY100S341JZ

Overview

The SY100S341JZ is an 8-bit bidirectional shift register from the 100K ECL series, manufactured by Microchip Technology. It features eight D-type edge-triggered flip-flops with parallel and serial inputs, housed in a 28-pin PLCC package. The device supports a maximum shift frequency of 600MHz and a clock-to-Q propagation delay of up to 1200ps. It operates within an extended supply voltage range of VEE = –4.2V to –5.5V, with a typical power supply current (IEE) of –102mA.

Feature Summary

• Supports parallel load, left/right shift, and hold functions via dedicated select inputs
• Includes internal 75kΩ input pull-down resistors for improved noise immunity
• Features voltage and temperature compensation for enhanced performance stability

Applications

• High-performance ECL systems requiring fast data shifting
• Bidirectional data buffering and storage applications
• Parallel-to-serial or serial-to-parallel conversion circuits

Procurement Notes

Verify that the specific JZ suffix corresponds to the lead-free Matte-Sn finish as documented in the ordering information. Confirm the component status, as official documentation indicates this part may be marked as not recommended for new designs. Ensure compatibility with standard 100K ECL logic levels and verify the operating temperature range requirements against the commercial grade specifications provided.

Selection Notes

Select this component when a high-speed 8-bit bidirectional shift register is required within an ECL architecture. It offers function and pinout compatibility with Fairchild F100K equivalents. Consider the 28-pin PLCC package constraint and ensure the design accommodates the specified VEE supply voltage range of –4.2V to –5.5V for optimal operation.

Part Context

This device belongs to the 100S/100K ECL logic family produced by Micrel, now part of Microchip Technology. It is designed for high-speed digital applications where low propagation delay and high shift frequencies are critical. The SY100S341 provides a robust solution for managing parallel and serial data streams in complex electronic systems utilizing ECL technology.
