Logic-Latches are common integrated circuits, also known as flip-flops, which are used to store or remember binary data or, in some cases, analog data. The CD74HCT259M96E4 is a CMOS Logic-Latch found in many applications from consumer electronics to complex weapons systems.
CD74HCT259M96E4 is a integrated circuit designed for high speed circuit applications commonly used in consumer electronics. It has a wide range of signal applications such as SRAM, EPROM, FIFO buffers, communication interface circuitries and memory interfacing. This device can switch data at high speed and it is relatively stable in terms of reliability.
The functionality of the CD74HCT259M96E4 is controlled by three basic inputs – a clock input (CK), a true data input (D) and a data reset input (Reset). The Reset input resets the device to a known state. When the CK input goes high, the current value of the true data input is latched into the device. This latch will remain in the device until either the CK input again goes low, or the Reset input is activated. The value of the true data input is then propagated to each of the 9 outputs.
The device outputs are open drain outputs, meaning that when an output is enabled, an external pull-up resistor is needed to obtain the logic high output. The input voltage levels for the device are CMOS compatible, meaning that the logic zero is less than 0.8V and the logic one is greater than 2V. The current drawn is microamp level, making it very power efficient.
The most common application of the CD74HCT259M96E4 is latch conversion. It can convert asynchronous inputs so that they must be clocked in order for the change to take effect. This allows for a faster clock rate and easier control of the data. It is also used for multiplexing digital signals from asynchronous devices onto a single data line. By converting the data to a synchronous form, the data can be multiplexed with other digital signals onto the same bus. This can reduce the number of buses needed, which in turn can reduce the size of the circuitry needed and make it more efficient. Additionally, the device can also be used for data synchronization, as it can take in asynchronous digital signals, latch them, and then output them in a synchronized format.
In conclusion, the CMOS Logic-Latch CD74HCT259M96E4 is widely used in high speed circuits, such as SRAM and EPROM, FIFO buffers, communication interface circuitries, memory interfacing and latch conversion applications. Its easy to use inputs and outputs, CMOS compatible input voltage levels, and low power consumption make it a popular choice for many applications.
