MC10E157FNR2G

Overview

The MC10E157FNR2G is a 5 V/EnECL Quad 2:1 Multiplexer in a 28-lead PLCC package. It contains four independent multiplexers with differential outputs controlled by individual Select (SEL) inputs. The device operates in PECL mode (VCC = 4.2 V to 5.7 V, VEE = 0 V) and NECL mode (VCC = 0 V, VEE = −4.2 V to −5.7 V). Maximum propagation delay is 550 ps from data input and 800 ps from select input. Power supply current is typically 38 mA at 25°C.

Feature Summary

• Four independent 2:1 multiplexers with differential ECL outputs
• Individual select control for each multiplexer channel
• Internal 50 kΩ input pulldown resistors
• ESD protection exceeding 2 kV human body model

Applications

• Random logic designs requiring independent channel selection
• High-speed signal routing in communication systems
• Clock distribution networks using EnECL logic families

Procurement Notes

Verify the FNR2G suffix indicates tape and reel packaging containing 500 units per reel. Confirm the G suffix denotes lead-free composition. Ensure the design supports surface mount assembly on a 28-lead PLCC footprint. Check that power supply requirements match the specified PECL or NECL voltage ranges for proper operation.

Selection Notes

Select this component when four independent 2:1 multiplexing functions are required within a single integrated circuit. The device is suitable for applications demanding high toggle frequencies up to 1100 MHz. Consider the 100 series variant if temperature compensation features are necessary for the specific operating environment.

Part Context

This part belongs to the MC10E/100E157 family of 5 V/EnECL quad 2:1 multiplexers. The 10E series represents standard performance, while the 100E series includes temperature compensation. Both variants share identical pinouts and electrical characteristics regarding propagation delays and supply currents.

Replacement Considerations

MC10E157FN serves as the non-reel equivalent. MC100E157FNR2G provides the same functionality with added temperature compensation.
