The CD74HCT390M96E4 is a Synchronous Binary Up/Down Counter. This device incorporates dual 4-bit binary synchronous up and down counter sections which are internally connected to provide modulo-16 (24) count operation. Synchronous counting is provided by having all flip-flops clocked simultaneously so that the outputs change coincident with each other when so instructed by the controlling circuitry.

The CD74HCT390M96E4 is constructed around its two dual 4-bit binary synchronous counters. Each one contains four Flip/Flop outputs that are connected in cascade to enable the counter to count from 0 to 15. The device incorporates two Clock Pulse inputs (CP0 and CP1) and a Mode input (Mode) which allows the counter to count either upward or downward.

The Mode input is used to control the direction of the count when CP0 is high. If the Mode input is a “1” the count will increment is CP0 goes low-to-high (up count). If the Mode input is a “0” the count will decrement if CP0 goes low-to-high (down count).

The CD74HCT390M96E4 can be used in a wide variety of applications including digital clocks and timers, frequency divider circuits and other digital counters. Its versatile architecture and synchronous counting capability offer great advantages for designers striving for circuits that can perform multiple functions. In addition to its counting capabilities, the device is also useful for addressing multiple output stages.

The CD74HCT390M96E4 is built on a low-power CMOS technology that offers higher speed and improved performance over traditional bipolar devices. The device is also capable of operating with a supply voltage range of 2.7V to 6.5V, making it ideal for low-voltage applications. In addition, the device is designed to dissipate very low power making it ideal for battery operated products.

Due to its versatility and low power dissipation, the CD74HCT390M96E4 is widely used in a wide variety of applications including automotive, agricultural, medical, and industrial control equipment. Its architecture and synchronous counting capability make it well-suited for digitally-controlled systems requiring fast and reliable counters.
