CD74HCT161EG4

Counter Dividers Overview

The CD74HCT161EG4 is a high-speed CMOS logic device functioning as a 4-bit binary synchronous counter. It features an asynchronous reset input and a terminal count output (TCO). The component operates within a supply voltage range of 2 V to 6 V and supports data rates up to 30 MHz. It is housed in a 16-pin Small Outline package (SOIC) with a narrow body, designed for surface-mount applications across an industrial temperature range of -55°C to 125°C.

Counter Dividers Feature Summary

• Synchronous counting operation with parallel load capability
• Asynchronous master reset functionality
• Terminal count output for cascading multiple stages

Counter Dividers Applications

• Digital timing circuits requiring precise frequency division
• Event counting systems in industrial control panels
• Address generation modules in memory addressing architectures

Counter Dividers Procurement Notes

Verify the specific suffix 'G4' indicates lead-free construction compliant with RoHS standards. Confirm the SOIC-16 package dimensions match the target PCB footprint. Ensure the operating environment remains within the specified -55°C to 125°C thermal limits to maintain signal integrity and prevent latch-up conditions during high-frequency switching operations.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit binary counter with asynchronous reset is required in a surface-mount design. The HCT series ensures compatibility with standard TTL logic levels while offering CMOS power efficiency. Consider the 16-pin SOIC package for space-constrained boards where through-hole alternatives are unsuitable.

Counter Dividers Part Context

This part belongs to Texas Instruments' CD74HCT family of high-speed CMOS logic devices. The '161' designation identifies it specifically as a 4-bit binary counter. The 'E' suffix denotes the SOIC package variant, while 'G4' confirms environmental compliance. It serves as a core timing element in digital sequential logic designs.

Counter Dividers Replacement Considerations

Direct pin-compatible substitutes include the CD74HC161E for HC series integration or the CD74AC161E for AC series performance. Verify that alternative logic families maintain compatible input thresholds and output drive strengths for the specific application circuit.
