MC100EP142FAR2G

Shift Registers Overview

The MC100EP142FAR2G is a 9-bit shift register from the ECLinPS family, designed for byte-parity applications. It supports serial/parallel to parallel data transfer with shifting in one direction (Bit 0 to Bit 8). The device features dual clocks (CLK0 and CLK1) and accepts parallel inputs D0-D8 and serial input S-IN. It operates in PECL mode with VCC ranging from 3.0 V to 5.5 V (VEE = 0 V) or NECL mode with VCC at 0 V and VEE from -3.0 V to -5.5 V. Key electrical parameters include a typical shift frequency exceeding 2.8 GHz, propagation delays of 500 ps to 800 ps depending on temperature, and an asynchronous master reset function.

Shift Registers Procurement Notes

Verify the specific suffix 'R2G' corresponds to the tape and reel packaging configuration as documented in the ordering information. Confirm that the component meets RoHS compliance standards and is lead-free. Ensure the procurement channel provides valid traceability for the assembly location and wafer lot codes indicated in the marking diagram.

Shift Registers Selection Notes

Select this component when designing systems requiring high-speed ECL logic with byte-oriented data handling. It is suitable for applications needing simultaneous serial and parallel data loading capabilities. Consider the thermal requirements, as airflow greater than 500 lfpm is recommended for operation at higher supply voltages or temperatures to maintain performance specifications.

Shift Registers FAQ

How does the SEL pin affect the operation mode?

The SEL pin switches between SHIFT and LOAD modes. When SEL is HIGH, the device shifts data; when LOW, it loads parallel data from D0-D8.

What is the function of the MR pin?

The Master Reset (MR) pin asynchronously resets all registers to zero, overriding the CLK0 and CLK1 inputs regardless of their state.
