Application Field and Working Principle of SN74LVC1G175DCKT
Introduction:
SN74LVC1G175DCKT is a logic and flip flop device from Texas Instruments. It is a 1-bit D-type bus buffer with a storage latch, designed for 1.65 to 5.5 V VCC supply voltage. It features - 0.8 to 5.5V VCCA (Auxillary Supply); -3.3 V tolerant outputs; 4 mΩ output resistive load and single power supply & dual power supply. It is also designed with watch-dog timer, pulse swapper and pin-strap mode support.
Application Field:
SN74LVC1G175DCKT can be used in a variety of applications including computing and network systems, cell phones, television and set-top box. It can be used in any application where data capture, data routing and data storage is needed. It is mainly used as a low-voltage data buffer and latch circuit, especially in cases where its low 2.7V-3.3V supply limits are beneficial. It is also suitable for automotive and consumer applications due to its low power consumption and reduced power-up time during system start-up.
Working Principle:
The SN74LVC1G175DCKT has two power supply types – single power supply and dual power supply. In single power supply, the device uses the same voltage for both input and output signals. Whereas, in dual power supply, the device uses separate voltages for the two type of signals. The device can be programmed to operate in either single power supply or dual power supply mode. It is capable of converting signals from one voltage level to another.
It works as a latch where it captures the data and stores it in a latch until the data is ready to be read out. The buffer then can be used to transfer the data to a higher voltage level or a lower voltage level, depending on the voltage supplied to the device. It is also capable of controlling the switching rate so that the data is not corrupted while in transfer.
The device has an additional feature- Watch-dog timer (WDT). The WDT monitors whether a certain sequence of events happens in a predetermined amount of time. If the sequence of events does not happen in a predetermined amount of time, the WDT will reset the system. This is used mainly to reset the system if there is any problem in the system. The WDT is not only used for system resets, but also for error detection (eg. Clock-domain crossing) and system recovery.
In addition, the SN74LVC1G175DCKT also has support for pin-strap mode. In the pin-strap mode, the device can be programmed to operate in either single power supply or dual power supply mode. In single power supply mode, the device always uses the same supply voltage, while in dual power supply mode, the device uses different supply voltages, depending on the type of output signal that needs to be transferred. This feature allows the device to operate as a buffer as well as a logic/flip flop circuit.
Conclusion:
The SN74LVC1G175DCKT is a logic/flip flop device designed for 1.65 to 5.5 V VCC supply and 0.8 to 5.5V VCCA (Auxiliary Supply) voltage. It works as a latch and buffer, capable of transferring signals from one voltage level to another. It has additional features such as watch-dog timer (WDT), pulse swapper and pin-strap mode which facilitate system reset, error detection and more. This device is mainly used in computing and network systems, cell phones, television and set-top box.
