MC100E150FNR2

Latches Overview

The MC100E150FNR2 is a 5V ECL/EnECL 6-bit D latch manufactured by onsemi. It contains six D-type latches with differential outputs and features temperature compensation characteristic of the 100 Series. The device operates in PECL mode (VCC = 4.2 V to 5.7 V, VEE = 0 V) or NECL mode (VCC = 0 V, VEE = -4.2 V to -5.7 V). It supports a maximum toggle frequency of 900 MHz at 0°C and 1100 MHz at 25°C. Propagation delay ranges from 250 ps to 800 ps depending on input source and temperature. It utilizes a 28-lead PLCC package.

Latches Feature Summary

• Contains six D-type latches with differential outputs and Master Reset functionality
• Features internal temperature compensation for stable performance across operating temperatures
• Includes internal 50 kΩ input pulldown resistors to stabilize inputs
• Provides electrostatic discharge protection exceeding 2 kV Human Body Model

Latches Applications

• High-speed digital data storage systems requiring differential signaling
• Clock distribution networks utilizing ECL logic families
• Data acquisition circuits interfacing with high-frequency sources
• Telecommunications equipment requiring robust latch timing control

Latches Procurement Notes

Verify the specific ordering suffix 'R2' indicates tape and reel packaging containing 500 units per reel. Confirm the component is the standard leaded version rather than the Pb-Free variant, which carries the 'G' suffix. Ensure the procurement specification matches the required 28-lead PLCC form factor. Cross-reference the manufacturer part number against current availability status as legacy components may have supply constraints.

Latches Selection Notes

Select this component when designing systems requiring six synchronized D-latches with differential outputs. The 100 Series designation ensures temperature compensation, making it suitable for environments with significant thermal variations compared to the standard 10 Series. Verify that the power supply architecture supports either PECL or NECL configurations. Ensure the PCB layout accommodates the 28-lead PLCC footprint and provides adequate thermal dissipation given the junction-to-ambient resistance specifications.

Latches Part Context

This device belongs to the MC10E/100E series of 5V ECL logic products. The 100 Series specifically incorporates temperature compensation circuitry to maintain consistent electrical characteristics over the commercial temperature range. It serves as a fundamental building block for complex sequential logic designs within high-speed communication and processing architectures where signal integrity and timing precision are critical.

Latches Replacement Considerations

The MC10E150FNR2 is the non-compensated equivalent within the same family. For lead-free requirements, the MC100E150FNR2G offers identical electrical performance with RoHS-compliant materials.
