MM74C165N

Shift Registers Overview

The MM74C165N is a Parallel-Load 8-Bit Shift Register manufactured by onsemi, utilizing CMOS technology. It operates within a supply voltage range of 3V to 15V and features dual clock inputs for flexible shifting control. The device provides complementary outputs (Q7 and Q7) and supports parallel loading independent of the clock state. Propagation delay ranges from 80 ns to 400 ns depending on voltage. It is housed in a 16-Lead Plastic Dual-In-Line Package (PDIP).

Shift Registers Feature Summary

• Parallel loading capability that functions independently of the clock signal state.
• Dual clock inputs allowing separate or combined operation from independent sources.
• Complementary serial outputs providing both Q7 and Q7 signals.
• Fully static operation with guaranteed noise margin.

Shift Registers Applications

• Data acquisition systems requiring parallel-to-serial conversion.
• Input expansion for microprocessor-based digital logic circuits.
• Sequential data processing applications using dual-clock control.

Shift Registers Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm package specifications match the 16-Lead PDIP requirement. Review datasheet electrical characteristics against specific operating conditions. Ensure environmental compliance aligns with project standards. Validate pinout compatibility during integration planning.

Shift Registers Selection Notes

Evaluate supply voltage requirements against the 3V to 15V operational range. Consider propagation delay limits for high-speed timing constraints. Assess noise immunity needs relative to the specified noise margins. Verify interface compatibility with driving logic families. Check temperature range suitability for the intended application environment.

Shift Registers Part Context
