CD74HC192PWG4 is a synchronous 4-bit binary up/down counter with load from the Texas Instruments semiconductor family. It is a member of the High-Speed CMOS logic family, which is designed to increase system performance and reduce the power consumption of systems. This device is capable of counting up to 16 with output dedicated pins for 0 to 15, making it suitable for a plethora of applications ranging from automation systems, security systems, and more.It operates in static mode and has two on-chip counting states: up/down. It is available in various package types such as SOIC, TSSOP, and also in SOP packages. The speed grades of the device range from 1 MHz to 20 MHz. It has five dedicated pins for power supply (Vcc1 and Vcc2), enabling and disabling of clock input (CLK), counting direction (DIR) and the asynchronous reset pin (RST). The logic function of the device allows the creation of an asynchronous reset function for the counter. When the RST pin is inactive, it enables the counter to count up and down. When the RST pin is used, it will reset the counter to the all-ones state. This allows the designer to integrate a reset system into their circuit if it is necessary.In terms of its application fields, this device can be an effective component in digital systems such as clocks, watches, alarms, counters and dividers. These applications demand accurate counting and clock generation capabilities, which the CD74HC192PWG4 can deliver effectively. Additionally, its versatility and counting capabilities also make it suitable for use in a wide array of other applications such as in sensor systems, data acquisition systems, switching systems, and communication systems. Working PrincipleThe working principle of the CD74HC192PWG4 is based on CMOS circuitry technology. It has four master-slave flip-flops which are triggered from the positive edge of the clock. When the enable input clock signal is high, the counter will enable the clock input and the counter will then start counting up or down based on the logic level of the DIR input. When the count reaches 15, the logic on the Q0 output will return to a high level and the counter will start counting from 0 again.The device also has two power supply pins (Vcc1 and Vcc2), which must be connected for proper operation. The power pins can respectively be used for Vcc1 = 5V and Vcc2 = 3.3V. The supply voltage of the device ranges from 2V to 6V, whereas the voltage between Vcc1 and Vcc2 should not exceed 6.5V. The operating temperature of the device should also be kept between -55°C and 125°C.The CD74HC192PWG4 provides many advantages including low power consumption. It also offers versatility, with the ability to control the count direction and reset modes. The device is also capable of counting up to 16, which makes it suitable for many applications where counting or clock generation is required. Furthermore, its low cost and long life make it an attractive choice for many applications.
