The MC74LVX574DTG is a high-speed, low-voltage, single-input flip-flop device. It has four D-type flip-flops with individual clock inputs, a common reset line and individually buffered outputs, each with a specified power-on reset state. Each flip-flop is clocked with the rising edge of its respective clock input. The triggering of the clock input is determined internally, allowing transition propagation times independent of VCC. The reset line is active low and overrides all other inputs to bring the outputs to their reset states. The output of each flip-flop is a static latch and is capable of driving up to 15 TTL loads. All outputs are designed to interface directly with TTL, ECL, MOS and CMOS data buses. The device also features a presettable synchronous set port and an electrically alterable non-volatile memory (KEY SLOT).

Application Field

The MC74LVX574DTG can be used in a wide range of applications, most commonly in memory buffering, synchronous buses, register files, address decoding and microprocessor applications. It is particularly suitable for applications where high performance and low power consumption are required. The device is widely used in communications networks, industrial automation, automotive systems, test and measurement equipment and medical instrumentation.

Working Principle

The MC74LVX574DTG utilizes an internal latch for each of the four flip-flops. When either the set (CLR) or reset (R) command is activated, all outputs go to the appropriate reset state. When the clock signal is received, it causes the data at the input (D) to be latched and the appropriate output (Q) is updated. Each of the four flip-flops operates independently of the other, ensuring that no matter the current state of the input and output, the data is accurately transferred.

The device also features a built-in ESD protection designed to protect against electrostatic discharge. This is especially important in applications where the MC74LVX574DTG is used in conjunction with other devices. The device\'s high-performance, low-power consumption, and comprehensive ESD protection make it the perfect choice for memory buffering, register files and other high-speed applications.
