CD74HCT85E is a high-speed and low-power-consumption logic device from Texas Instruments. It is a quad 2-input EXCLUSIVE-OR gate and is composed of two D-Type latches. It is used for implementing buffer functions, for single-bit memory, and for complicated logic functions. This high-performance device is pin- and function-compatible both with HCT and LS versions. The device belongs to the Logic - Comparators and is frequently used in computer and telecommunication networks, industrial and consumer application, precision and portable instruments, etc.
The main features of CD74HCT85E include low power consumption and a wide operating temperature range. The device has a low static power consumption of 0.6 watts and a low dynamic power consumption of 0.1 watt. It also has a wide operating temperature range of -55 to +125 degree Celsius. Its logic threshold voltages are 3V and 5V, making it compatible with both TTL and CMOS logic families. Its hysteresis voltage is 2V and its 2-input EXCLUSIVE-OR function has an output which is the logical OR of the two inputs.
CD74HCT85E functions mainly by comparing two analog signals. The signals are paired with each other and compared for perfect matching or for relative similarities or differences. When two analog signals are compared and the corresponding digital output is obtained, it is known as Half-subtractor. And when the two analog signals are compared to detect a match between them, it is called as Full adder. Full-subtractor is the differentiating operation between two analogue signals.
The main application fields of the CD74HCT85E include computer and telecommunication networks, industrial and consumer applications, precision and portable instruments, etc. This device is especially useful for use in synchronous and asynchronous designs that require maximum speed and power efficiency. Additionally, CD74HCT85E is well-suited for use in voice, video and data communications applications. The device is ideal for adding, deleting, inverting and combining digital signals. CD74HCT85E is used primarily to decode digital signals, act as switches and transmit digital signals between memory and device_registers.
The main working principle of CD74HCT85E is to compare two different input signals. It compares the two signals in order to detect a match between them and provide a digital output accordingly. When two different analog signals are applied to the two inputs, the device compares the two signals and produces a logic 1 output if there is a match, and a logic 0 if the signals fail to match. The output of the device is proportional to the difference between the two input signals.
CD74HCT85E is especially well-suited for applications where speed and power efficiency are of utmost importance such as in precision instruments, industrial, consumer and telecommunication networks. The device has a low static power consumption of 0.6 watts and a wide operating temperature range of -55 to +125 degree Celsius which makes it useful for applications running in extreme temperature conditions. It has a wide operating threshold voltage range, making it compatible with both TTL and CMOS logic families. Additionally, it is also ideal for adding, deleting, inverting and combining digital signals.
To conclude, CD74HCT85E is a high-speed and low-power-consumption logic device from Texas Instruments. It is used in many application fields such as in computer and telecommunication networks, industrial and consumer application, precision and portable instruments, etc. The device functions by comparing two analog signals in order to detect a match between them and produce a digital output. It has a low static power consumption and a wide operating temperature range which makes it ideal for applications in extreme temperature conditions. Therefore, CD74HCT85E is a great choice for use in synchronous and asynchronous designs that require maximum speed and power efficiency.
