Overview
The SN74HC4020DBRG4 is a 14-bit asynchronous binary counter manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and utilizes a 16-pin SSOP package. The device advances on the negative-going edge of the clock pulse and resets asynchronously when the clear input goes high. Key electrical characteristics include a maximum propagation delay of 38 ns at 6 V, a typical delay of 12 ns, and a maximum supply current of 80 µA.
Feature Summary
- Features a 14-stage binary ripple-carry architecture that advances on the negative-going edge of the clock pulse.
- Provides an asynchronous reset function that clears all outputs to zero independently of the clock input.
- Supports operation across a wide supply voltage range from 2 V to 6 V with low power consumption.
Applications
- Digital frequency division circuits
- Time-base generation for digital clocks
- Event counting in industrial control systems
Procurement Notes
Verify the specific ordering suffix 'DBR' corresponds to the SSOP package variant during procurement. Confirm RoHS compliance status as indicated in the manufacturer's documentation. Ensure the component status is checked against the latest product life cycle data to confirm availability for production.
Selection Notes
Select this component for designs requiring a 14-bit count capacity with asynchronous reset functionality. Consider the SSOP package dimensions for board space constraints. Evaluate the operating temperature range requirements against the specified -40°C to 85°C limit for commercial applications.
Part Context
This part belongs to the SNx4HC4020 family of 14-bit asynchronous binary counters. The family includes variants such as SN74HC4020D (SOIC) and SN74HC4020N (PDIP). The HC logic series offers CMOS performance with standard TTL load driving capabilities.
Replacement Considerations
SN74HC4020DR is a tape-and-reel version of the same SOIC package. SN74HC4020PWR is a TSSOP package alternative. Verify pinout compatibility before substitution.
