SN74HC4020 Description

Short technical summary and product information.

The SN74HC4020 from Texas Instruments is a 14-stage binary ripple-carry counter. It advances on the negative-going edge of the clock pulse and can be reset to zero independently of the clock input when the clear input goes high.

 

This counter features a wide operating voltage range from 2 V to 6 V, making it versatile for various applications. It offers low power consumption with a maximum ICC of 80 µA and a typical propagation delay of 12 ns. The outputs can drive up to 10 LSTTL loads, with ±4 mA output drive at 5 V. Input current is also low, at a maximum of 1 µA.

 

The SN74HC4020 is available in multiple package types including SOIC, PDIP, TSSOP, CDIP, LCCC, and CFP, catering to different board space and assembly requirements. Its operating temperature range is -40 °C to 85 °C.

 

This device is suitable for applications requiring precise counting and timing functions within digital systems.
