MC100E457FNR2G

Overview

The MC100E457FNR2G is a 5 V ECL triple differential 2:1 multiplexer in a PLCC-28 package. It features fully differential data paths for low skew clock multiplexing with >1.0 GHz bandwidth. The device supports PECL (VCC = 4.2 V to 5.7 V, VEE = 0 V) and NECL (VCC = 0 V, VEE = −4.2 V to −5.7 V) modes. Key electrical parameters include a maximum propagation delay of 700 ps, a maximum toggle frequency of 1.1 GHz, and internal input clamp structures that force outputs LOW during open input conditions.

Feature Summary

• Fully differential data path designed for low skew clock or skew-sensitive signal multiplexing
• Internal input clamp structures ensure Q output goes LOW when inputs are open
• Temperature compensation included within the 100 Series architecture
• Multiple VBB pins provided to facilitate AC coupling input signals

Applications

• Multiplexing low skew clock signals
• Data path applications requiring separate select lines
• Random logic applications utilizing common select lines

Procurement Notes

Verify the specific ordering suffix against current manufacturer documentation to confirm package type and shipping quantity. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration. Ensure all VCC, VCCO, and VEE pins are externally connected to power supplies to guarantee proper operation as specified in the datasheet warning.

Selection Notes

Select this component for high-frequency applications requiring differential signal routing with minimal skew. The device accommodates both PECL and NECL operating ranges, providing flexibility for various power supply configurations. Verify that the system design can support the required termination voltages and that thermal management meets the junction-to-ambient resistance specifications for the target environment.

Part Context
