Overview
The SN74HC4040APW is a 12-bit asynchronous binary counter from the Texas Instruments 74HC series. It operates on a single supply voltage ranging from 2 V to 6 V and supports a maximum counting rate of 33 MHz. The device utilizes negative-edge-triggered flip-flops for up-counting operations and features an asynchronous reset input. It is housed in a 16-pin TSSOP package and functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Provides 12-bit asynchronous binary up-counting capability using negative-edge-triggered flip-flops.
- Includes an asynchronous reset function to clear all counter outputs independently of the clock signal.
- Operates across a wide supply voltage range of 2 V to 6 V with high noise immunity typical of HC logic.
Applications
- Frequency division circuits
- Digital timing sequences
- Event counting systems
Procurement Notes
Verify the specific suffix 'APW' corresponds to the 16-TSSOP package variant when sourcing. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Ensure the ordering part number matches the required package style and temperature grade for your design.
Selection Notes
Select this component for designs requiring 12-bit asynchronous counting within the standard 74HC logic family specifications. It is suitable for applications needing a wide supply voltage range and moderate speed performance up to 33 MHz. Consider the TSSOP package constraints for PCB layout and thermal management during integration.
Part Context
This device belongs to the SN74HC4040 family of 12-bit asynchronous binary counters manufactured by Texas Instruments. The HC designation indicates High-speed CMOS technology, offering compatibility with standard TTL inputs while providing low power consumption. The APW suffix specifically identifies the TSSOP-16 surface-mount package configuration.
