SN74HC4040PWG4

Counter Dividers Overview

The SN74HC4040PWG4 is a 12-bit asynchronous binary counter from the Texas Instruments 74HC series. It operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range of -40°C to +85°C. The device features a high-level clear input that asynchronously resets all outputs low, with counting advanced on high-to-low clock transitions. It utilizes a 16-pin TSSOP package.

Counter Dividers Feature Summary

• Provides 12-stage asynchronous binary counting with all stage outputs available externally
• Features asynchronous clearing via a high-level signal at the clear input
• Supports operation across a wide voltage range of 2 V to 6 V
• Designed for low power consumption with minimal input current requirements

Counter Dividers Applications

• Time-delay circuits
• Counter controls
• Frequency-dividing circuits

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'G4' against the manufacturer's latest documentation to confirm compliance with RoHS3 standards and lead finish specifications. Confirm the active production status and moisture sensitivity level ratings prior to finalizing procurement orders to ensure compatibility with assembly processes.

Counter Dividers Selection Notes

Select this component when a 12-bit asynchronous binary counter is required in a surface-mount TSSOP-16 package. Ensure the design accommodates the HC logic family voltage levels and timing characteristics. Verify that the application does not require synchronous counting or integrated oscillator functions, which are distinct from this counter-only architecture.

Counter Dividers Part Context

This part belongs to the SNx4HC4040 family of 12-bit asynchronous binary counters manufactured by Texas Instruments. The 'SN74' prefix indicates standard commercial grade performance, while the 'HC' designation specifies High-speed CMOS technology. The 'PW' suffix identifies the 16-pin Thin Shrink Small Outline Package (TSSOP).

Counter Dividers Replacement Considerations

Direct equivalent replacements include SN74HC4040PWR and SN74HC4040PWT. Cross-manufacturer alternatives such as MC74HC4040ADTR2G and 74HC4040PW,118 are also documented as parameter-equivalent substitutes.
