SN74F161ADR

Counter Dividers Overview

The SN74F161ADR is a synchronous 4-bit binary counter from the Texas Instruments 74F series. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum counting rate of 100 MHz. The device features positive-edge triggering and asynchronous reset functionality. It is housed in a 16-SOIC package with a width of 3.90 mm. The component functions as a single circuit element with four bits per element, designed for up-counting operations across an operating temperature range of 0°C to 70°C.

Counter Dividers Feature Summary

• Synchronous 4-bit binary counting architecture with positive-edge clock triggering
• Asynchronous reset capability for immediate state clearing
• High-speed operation supporting counting rates up to 100 MHz

Counter Dividers Applications

• Digital frequency division circuits
• Sequential logic timing control systems
• Binary data accumulation and processing units

Counter Dividers Procurement Notes

Verify the specific suffix ADR confirms the tape-and-reel packaging format suitable for automated surface-mount assembly processes. Confirm RoHS3 compliance status and湿气敏感性等级 (MSL) classification prior to integration into moisture-sensitive production lines. Ensure the 16-SOIC footprint matches the target PCB design constraints.

Counter Dividers Selection Notes

Select this component when high-speed synchronous counting is required within standard 5V logic environments. The 74F series offers faster propagation delays compared to LS or HC variants. Verify that the 100 MHz maximum frequency aligns with system clock requirements and that the SOIC-16 package fits the available board space.

Counter Dividers Part Context

This part belongs to the Texas Instruments SN74F161A family of synchronous 4-bit binary counters. It shares functional compatibility with other industry-standard 74F161 devices while providing TI-specific manufacturing quality and packaging options. The ADR suffix specifically denotes the reel-based packaging variant for efficient high-volume surface-mount placement.

Counter Dividers Replacement Considerations

SN74F161ADRG4 is a verified alternate ordering suffix for the same functional device with potentially different packaging or environmental compliance attributes.
