MC100EP142FA

Shift Registers Overview

The MC100EP142FA is a 9-bit shift register from the 100 Series, designed for byte-parity applications. It supports serial/parallel to parallel output conversion with unidirectional shifting. The device operates in PECL mode (VCC = 3.0 V to 5.5 V, VEE = 0 V) and NECL mode (VCC = 0 V, VEE = -3.0 V to -5.5 V). It features dual clocks (CLK0, CLK1), asynchronous master reset, and temperature compensation. Maximum shift frequency exceeds 2.8 GHz typical. Propagation delay ranges from 500 ps to 800 ps depending on conditions. Power supply current is typically 125 mA at 25°C.

Shift Registers Feature Summary

Shift Registers Procurement Notes

Verify the FA suffix indicates LQFP-32 packaging. Confirm RoHS compliance and lead-free status. Check for moisture sensitivity level requirements during storage and handling. Ensure power supply decoupling meets thermal recommendations for airflow.

Shift Registers Selection Notes

Select this component for high-frequency ECL applications requiring 9-bit shift capability. Consider thermal management if operating near maximum voltage limits. Verify interface compatibility with differential clock sources. Evaluate power consumption against system constraints.
