Description and Introduction

Dual decade ripple counter The 74HC390D is a dual decade ripple counter manufactured by PHI (Philips). It is a high-speed CMOS device that operates with a supply voltage range of 2V to 6V. The 74HC390D features two independent 4-bit ripple counters, each with a divide-by-2 and a divide-by-5 section. It has a typical propagation delay of 20 ns and a maximum clock frequency of 50 MHz. The device is available in a 16-pin SOIC (Small Outline Integrated Circuit) package. It is designed for use in applications such as frequency division, time delay generation, and digital counting. The 74HC390D is compatible with TTL (Transistor-Transistor Logic) inputs and outputs, making it suitable for interfacing with both CMOS and TTL logic levels.
