MC10H164MELG

Overview

The MC10H164MELG is a high-speed synchronous presettable cascadable 4-bit binary counter from the onsemi 10H series. It operates with a negative supply voltage ranging from -4.94V to -5.46V and supports a minimum counting frequency of 200 MHz. The device features positive edge triggering, load/preset inputs, and MECL 10K compatibility. It is housed in a 16-SOEIAJ surface-mount package and functions within a commercial temperature range of 0°C to 75°C.

Feature Summary

• High-speed synchronous operation with a minimum counting frequency of 200 MHz
• Positive edge triggered with load and preset capabilities for flexible control
• Compatible with MECL 10K logic standards for system integration

Applications

• Digital conversion systems requiring precise timing
• Cascadable digital counting applications
• High-speed digital integration circuits

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm package integrity as the 16-SOEIAJ form factor requires specific handling. Ensure supply chain documentation matches the manufacturer's obsolescence notices. Validate that the negative voltage supply requirements align with existing system designs before procurement.

Selection Notes

Select this component when MECL 10K compatibility and high-speed synchronous counting are required. The 4-bit architecture suits applications needing compact binary counters. Consider the 16-SOEIAJ package constraints for PCB layout. Verify that the negative power supply infrastructure supports the specified operating voltage range for reliable performance.
