Logic-Latches are electronic circuit components that are used to store information, far beyond the life of a power supply. This is why they are widely preferred in high-reliability applications. SN74HC563NG4 is a 8-bit D-type latch developed by Texas Instruments, which is widely used for multiple purposes. The device features synchronous active-low enable inputs, reset and set pins, and data outputs. This section will introduce the application field and working principle of the SN74HC563NG4.
The SN74HC563NG4 is a 8-bit D-type latch, and it is commonly used in low-power applications, such as memory scanning, digital electronics, and embedded system design. It also features synchronization, reset, and set pins for further use in various digital circuits. Its active-low enable inputs allow fast control and flexibility in terms of design. Thanks to its low power consumption, it is also suitable for battery-powered devices. Also, it has a large operating temperature range of -40 to 85 degree Celsius, making it popular in a wide range of applications.
The SN74HC563NG4’s schematic symbol can be seen as followed, showing the latch’s main components including four NAND gates, four buffers, latch enable input, and reset/set pin.
The operation of the latch can be explained using the truth table shown below. The active-low enable input (EN) allows for fast control of data path. An active low signal on the reset pin (R) will reset the contents of the latch, as seen in row 0. Similarly, an active low signal on the set pin (S) will set the contents of the latch to "1", as can be seen in row 1. Furthermore, when both reset and set pins are set to "HIGH", the latch will retain the current value of data on the data inputs (D).
In terms of performance, the SN74HC563NG4 has a high noise immunity index of up to 4KV/us, which makes it suitable for harsh environments. Also, its speed is quite impressive, with an output transition of 1.0ns and a typicall propagation delay of 3.2ns at 5V supply voltage. This makes it suitable for high-speed applications, such as real-time clock circuits.
Belonging to the low-power logic family, the SN74HC563NG4 is widely used in memory scanning, digital electronics, and embedded system design. Its reset and set pins, active-low enable input, and synchronous behaviour give it great flexibility and control in terms of design. Furthermore, its low power consumption and great speed make it a preferred choice in high-reliability and high-speed applications.
