MC10H159FNR2

Overview

The MC10H159FNR2 is a quad 2-input multiplexer with enable, belonging to the MECL 10H series. It features inverted outputs and operates on dual power supplies ranging from -4.94V to -5.46V. The device provides a typical propagation delay of 1.5 ns and dissipates approximately 218 mW. It utilizes a 20-PLCC (J-Lead) surface-mount package.

Feature Summary

• Provides common enable and data select inputs for synchronized channel selection across four independent multiplexers.
• Features voltage compensated design ensuring improved noise margins over the full operating voltage and temperature range.
• Delivers functional and pinout compatibility with the standard MECL 10K family while offering significantly faster propagation delays.

Applications

• High-speed digital signal routing in telecommunications equipment
• Data acquisition systems requiring rapid analog or digital channel switching
• Test and measurement instrumentation utilizing differential logic interfaces

Procurement Notes

Verify that the specific order suffix matches the required tape and reel packaging configuration. Confirm RoHS compliance status if environmental regulations apply, as non-compliant variants exist within the same product line. Ensure the supply voltage aligns with the specified dual-rail requirements for proper operation.

Selection Notes

Select this component when MECL 10K compatibility is required alongside superior speed performance. Consider the 20-PLCC package constraints for PCB layout. Evaluate thermal dissipation capabilities given the typical power consumption levels inherent to the MECL 10H architecture during continuous operation.

Part Context

This part belongs to the MECL 10H high-speed logic family manufactured by onsemi. It serves as an upgraded replacement for legacy MECL 10K devices, maintaining identical pinouts while doubling speed performance without increasing power consumption. The FNR2 suffix specifically denotes the 20-lead plastic leaded chip carrier package with tape and reel shipping.

FAQ

How does the MC10H159 handle input signals?

Input levels are inverted at the output. A high select level enables data inputs D00, D10, D20, and D30, while a low level enables D01, D11, D21, and D31.

What is the relationship between MC10H159 and MECL 10K?

The MC10H159 is a functional and pinout duplication of the standard MECL 10K family part, providing a 100% improvement in propagation delay with no increase in power-supply current.
