SN74HC4020DR Description

Short technical summary and product information.

The SN74HC4020DR from Texas Instruments is a 14-stage asynchronous 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 operates across a wide voltage range of 2 V to 6 V and has a typical count rate of 33 MHz. Its outputs can drive up to 10 LSTTL loads, and it offers ±4-mA output drive at 5 V. The device consumes low power, with a maximum ICC of 80 µA, and features a low input current of 1 µA max.

 

The SN74HC4020DR is available in a 16-SOIC package with surface mount mounting type. It is designed for an operating temperature range of -40°C to 85°C.

 

Key electrical characteristics include a typical propagation delay of 12 ns. The counter is asynchronous in its timing and reset functions, and it counts in an upward direction.
