MC10161P

Overview

The MC10161P is a high-speed binary counter integrated circuit manufactured by onsemi. It operates within the ECL 10H logic family, utilizing a 16-pin PDIP package for through-hole mounting. The device functions as a four-bit up-counter with asynchronous reset capabilities and positive-edge triggering. It supports a nominal negative supply voltage of -5.2 V and is rated for an operating temperature range from -30°C to 85°C. This component is designed for applications requiring reliable synchronous counting in differential Schmitt trigger environments.

Feature Summary

• Asynchronous reset functionality allows immediate clearing of count states independent of the clock signal.
• Positive-edge triggered operation ensures precise synchronization with input clock transitions.
• Differential Schmitt trigger inputs provide noise immunity and clean signal shaping for high-speed data transmission.

Applications

• High-speed digital counting systems
• Frequency division circuits
• Timing sequence generators

Procurement Notes

Verify the specific suffix 'P' confirms the 16-pin PDIP package configuration. Confirm RoHS compliance status as historical documentation may indicate non-compliance. Ensure the supplier provides valid traceability for this discontinued or legacy part number. Check for alternative sourcing channels if original manufacturer stock is unavailable.

Selection Notes

Select this component when a four-bit binary counter with asynchronous reset is required in a through-hole design. The ECL 10H family offers high-speed performance suitable for demanding timing applications. Verify that the system power supply aligns with the -5.2 V nominal requirement. Consider package constraints and thermal management within the specified -30°C to 85°C operating range.

Part Context

This part belongs to the onsemi ECL 10H series, known for high-speed logic operations. It serves as a fundamental building block for sequential logic designs. The PDIP-16 package facilitates easy prototyping and integration into legacy board layouts. It complements other devices in the 10H family for complex digital system construction.

Replacement Considerations

Consult official cross-reference guides for pin-compatible alternatives within the ECL logic family. Verify electrical characteristics match the original specifications before substitution. Legacy distributors may offer surplus stock from Rochester Electronics or similar sources.
