SY10E143JC

Overview

The SY10E143JC is a high-speed 9-bit hold register designed for ECL systems. It features dual clock inputs (CLK1, CLK2) and an asynchronous Master Reset (MR). The device accepts parallel data on D0-D8 and operates in HOLD or LOAD modes via the SEL pin. It supports byte-parity applications and pipeline registers. Operating frequency reaches 700 MHz minimum. Power supply current is typically 120 mA for 10E levels and 120-138 mA for 100E levels at +25°C. Propagation delay is 600-800 ps. It uses a 28-pin PLCC package.

Feature Summary

• Supports dual clock inputs for flexible synchronous operation
• Includes asynchronous master reset to clear all registers
• Features internal input pulldown resistors
• Compatible with standard 10KH and 100K ECL logic levels

Applications

• High-performance ECL systems
• Pipeline registers
• Byte-wide parity applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm lead finish and packaging type. The 'JC' designation indicates a commercial temperature range and Sn-Pb lead finish in the 28-pin PLCC package. Confirm RoHS compliance status if required, as Pb-free variants exist under different part numbers. Ensure the component meets the voltage requirements for the intended ECL power supply configuration before procurement.

Selection Notes

Select this component when designing circuits requiring 9-bit data storage with dual-clock capability. It is suitable for applications needing byte-wide parity checking or high-speed pipeline stages. Verify that the system operates within the specified VEE range of -4.2V to -5.5V for extended compatibility. Ensure the design accommodates the typical power supply current consumption and propagation delays associated with ECL logic families.

Part Context

This device belongs to the SY10/100E143 series of high-speed hold registers. It is fully compatible with industry-standard Motorola MC10E/100E143 devices. The series is engineered for new, high-performance ECL systems, offering reliable data holding and loading functions through parallel inputs and dedicated control pins.

Replacement Considerations

The SY10E143JC is fully compatible with the Motorola MC10E143. Designers may consider equivalent parts from other manufacturers that match the 9-bit width, dual-clock architecture, and ECL voltage levels. Verify pinout and electrical characteristics against the original datasheet before substitution.
