Product Description

The CD74HC390M96 features two independent decade counters that can be configured either separately or in various combinations to count specific sequences. Each counter has its own clock input, reset input, and 4-bit binary output. The reset input can set the counter to its zero state when a high level is applied. The IC's high-speed performance is characterized by a typical propagation delay of 13 ns with a 5V power supply, ensuring swift and reliable counting for high-speed applications.

Its robust design allows for a wide operating temperature range of -55°C to 125°C, which ensures functionality across extreme environmental conditions. The device's low power consumption is a significant advantage for power-sensitive applications, with a maximum quiescent current of only 20 µA at 25°C.

The CD74HC390M96 comes in a compact SOIC-16 package, which is ideal for space-constrained applications that require surface-mount technology. With its high noise immunity, the IC is resilient against spurious voltage spikes and glitches, ensuring stable operation in electronically noisy environments.

Overall, the CD74HC390M96 from Texas Instruments is an excellent choice for applications requiring a reliable and efficient dual decade ripple counter with CMOS technology benefits such as low power consumption and high noise immunity.
