MC10H159L

Overview

The MC10H159L 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 incorporates common enable and data select inputs for channel selection. The component is housed in a 16-CDIP package and supports an operating temperature range of 0°C to +75°C.

Feature Summary

• Provides functional and pinout compatibility with the standard MECL 10K family while delivering improved propagation delay performance without increasing power-supply current consumption.
• Features voltage-compensated design characteristics that ensure an improved noise margin of 150 mV across the entire operating voltage and temperature range.

Applications

• High-speed digital signal routing and switching applications requiring low latency.
• System designs necessitating direct replacement or upgrade of legacy MECL 10K logic components.
• Data acquisition systems utilizing differential signaling interfaces.

Procurement Notes

Verify the specific ordering suffix 'L' corresponds to the CDIP-16 ceramic package configuration required for your assembly process. Confirm that the procurement source accepts non-RoHS compliant components, as this specific variant does not meet RoHS standards. Ensure technical specifications align with existing system power supply rails and thermal management capabilities before finalizing orders.

Selection Notes

Select this component when upgrading from MECL 10K families to achieve faster switching speeds without altering board layout due to identical pinouts. Consider the dual power supply requirement and negative voltage operation inherent to the MECL 10H architecture. Evaluate the 16-CDIP package constraints against available PCB space and mounting requirements for through-hole integration.

Part Context

This part belongs to the MC10H159 series manufactured by onsemi. The series includes variants such as MC10H159M (SOEIAJ-16) and MC10H159P (PDIP-16). All variants share the same internal quad 2-input multiplexer functionality but differ in physical packaging and mounting style to accommodate diverse manufacturing needs.

Replacement Considerations

The datasheet identifies the MC10H159L as a functional and pinout duplication of the standard MECL 10K family parts. Designers replacing older MECL 10K components should verify that the improved propagation delay parameters are compatible with their timing budgets.
