SN74LV4040ARGYR

Counter Dividers Overview

The SN74LV4040ARGYR is a 12-bit asynchronous binary counter from Texas Instruments, part of the LV-A logic series. It operates within a supply voltage range of 2 V to 5.5 V and supports an operating temperature range of -40°C to +85°C. The device features a 16-VQFN (4x3.5) package with SMD/SMT mounting style. It performs up-counting operations with negative edge triggering and includes external access to all stage outputs.

Counter Dividers Feature Summary

• Provides external access to all internal counter stages for comprehensive state monitoring
• Supports asynchronous reset functionality for immediate counter initialization
• Enables high-speed counting operations suitable for demanding digital applications

Counter Dividers Applications

• Digital frequency division circuits
• Time-base generation in timing systems
• Address decoding in memory architectures

Counter Dividers Procurement Notes

Verify the specific package variant, as the LV4040A series is available in multiple form factors including TSSOP-16 and VQFN-16. Confirm that the ordering suffix matches the required physical dimensions and pinout. Ensure compatibility with the target board's thermal management requirements given the small footprint of the VQFN package.

Counter Dividers Selection Notes

Select this component when a 12-bit count capacity is required with low voltage operation down to 2V. The LV-A series offers improved performance over standard HC logic at lower voltages. Consider the VQFN package for space-constrained designs requiring surface mount technology.

Counter Dividers Part Context

This device belongs to the SN74LV4040A family of 12-bit asynchronous binary counters. It shares functional similarities with other members like the SN74HC4040 but utilizes Low-Voltage CMOS technology for enhanced efficiency at reduced supply voltages. The ARGYR suffix specifically denotes the 16-pin VQFN packaging option.
