Logic - Flip Flops

Flip-flops, one of the most common elements of logic circuits, are digital devices that change state as a result of signals. The SY100EL29VZI is one such device, an integrated voltage translator and octal D-Type flip-flop that operates from a 4.5V to 5.5V power supply. This device is used to translate logic levels between powered and non-powered environments, providing a buffer between the two.

Applications

The SY100EL29VZI is useful in a number of applications. It is often used to convert signals between different power domains, such as between a 3.3V and 5V environment. It can also be used in applications where isolating logic between two power supplies is necessary. In addition, this device is often used in applications that require synchronization, such as high-speed bus communication.

Working Principle

The device consists of eight D-type flip-flops with individual data (D) and clock (CLK) input pins. Each flip-flop has an associated set-up pin (C1, C2, C3, C4) that sets the state of the flip-flop. Each flip-flop also has an associated reset pin (R1, R2, R3, R4) that resets the flip-flop. The device is a non-latching translator, meaning that the data is only sampled and stored on the rising edge of the clock cycle. When the clock rises, the sampled data is stored in the flip-flop and can then be output to the destination power domain. The flip-flops remain in their current state until the next rising edge of the clock. The device is also designed so that it can operate at up to 50MHz clock speed, providing a high-speed data transfer between the two power domains. This makes the device suitable for high-speed data transfer applications, such as bus communication.

Conclusion

The SY100EL29VZI is an integrated voltage translator and octal D-Type flip-flop device that operates from 4.5V to 5.5V. It is useful in a number of applications, such as converting signals between two power domains and providing a buffer between the two, and is suitable for high-speed data transfer applications due to its capability of operating at up to 50MHz clock speed. The device consists of eight D-type flip-flops with individual data (D) and clock (CLK) inputs and a set-up and reset pin for each flip-flop. The device is a non-latching translator, meaning that data is only sampled and stored on the rising edge of the clock cycle.
