Logic - Latches

CY74FCT2373CTQCTE4 is a 16-bit edge-triggered flip-flop, faster and smaller than other conventional logic latches. It is a high-speed, low-power TTL (Transistor–Transistor Logic) device, with extended power supply voltage range. This latch has improved power and reduces EMI noise due to transition times, allowing for faster speeds and providing low-cost "glue logic" solutions.

The latch has a single latch cascade structure, with an output data latch on the rising and falling edge of the clock input. This features immediate action, improves the latency and simplifies the clock synchronization process. It is well-suited for applications where low-latency is a requirement.

This latch supports various diverse applications, including high-speed data-switching, synchronous communication buses, frequency generation, timing interrupts, memory address latch, and digital clock logic. It is capable of handling up to 8-bits of data, enabling it to provide multiple levels of logic for complex systems.

Working principle

The CY74FCT2373CTQCTE4 latch works on the premise of Edge-Triggered Flip-Flop. When the clock pulses transition from high to low, its output is latched on the rising edge of the clock. The output is immediately released when the clock input returns to its high state.

This latch is designed to offer improved power and reliability when compared to traditional logic latches. Its smaller design is designed to reduce the size of the circuit board and minimize the number of I/O pins needed. Additionally, it offers lower pin switching times, which helps reduce EMI noise from transitions, allowing for faster speeds.

The CY74FCT2373CTQCTE4 latch is suitable for use in a variety of applications such as clock control, data coding and controlling synchronous logic, memory address latch, and high-speed data switching. Its simplified architecture and versatility make it advantageous in applications where small total footprint and fast switching times are required.

Conclusion

The CY74FCT2373CTQCTE4 latch is a high-speed, low-power TTL device offering a wide range of features and applications. Its compact design and improved switching times allow for faster speeds and lower total power consumption. Additionally, its reduced pin count and smaller footprint size enable it to fit in tough spaces. These various advantages of the latch make it an ideal choice for a variety of applications.
