SN74HC4040PW

Counter Dividers Overview

The SN74HC4040PW is a 12-stage asynchronous binary counter in a 16-pin TSSOP package. It operates on a supply voltage of 2 V to 6 V and supports an operating temperature range of -40°C to 85°C. The device features a maximum clock frequency of 33 MHz at 6 V, with typical propagation delays of 12 ns. It includes an asynchronous clear input that resets all outputs low upon receiving a high level.

Counter Dividers Feature Summary

• Provides 12 external output stages for binary counting
• Asynchronously clears all outputs via the CLR input
• Advances count state on high-to-low clock transitions
• Compatible with LSTTL loads

Counter Dividers Applications

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

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'PW' corresponds to the TSSOP-16 package variant. Confirm RoHS compliance status and lead finish details through the manufacturer's current orderable addendum or packaging information sheet, as these attributes may vary by production lot.

Counter Dividers Selection Notes

Select this component when a 12-bit asynchronous binary counter is required within standard logic families. Ensure the design accommodates the asynchronous nature of the clear function and the specific timing requirements associated with the HC series propagation delays under the target supply voltage conditions.

Counter Dividers Part Context

This part belongs to the Texas Instruments SN74HC4040 family of 12-bit asynchronous binary counters. The 'PW' suffix specifically identifies the Thin Shrink Small Outline Package (TSSOP) with 16 pins. Other variants in the family include SOIC, PDIP, and SSOP packages.

Counter Dividers Replacement Considerations

SN74HC4040PWR is the active tape-and-reel version of the same TSSOP package.
