M74HC74RM13TR CMOS dual D-type flip-flop chip
The M74HC74RM13TR from STMicroelectronics is a high-speed CMOS dual D-type positive-edge-triggered flip-flop with asynchronous preset and clear functions, housed in a compact 14-SOIC package. It operates over a wide supply voltage range of 2V to 6V and is rated for the extended industrial temperature range of -55°C to +125°C. This chip integrates two independent flip-flops, each with individual data, clock, set, and reset inputs, making it a fundamental building block for sequential logic circuits.
It features buffered inputs for improved noise immunity and supports a maximum clock frequency of 67 MHz, enabling high-speed data latching and synchronization. With a low static current consumption of just 2µA (typical), it is suitable for power-sensitive applications. The device offers a high output drive capability of 5.2mA, allowing it to drive up to 10 LSTTL loads directly . Its asynchronous preset and clear inputs provide immediate control over the output state independent of the clock signal, enhancing system control. The wide operating voltage range ensures compatibility with various logic levels, from 3.3V to 5V systems.
The M74HC74RM13TR is engineered as a versatile logic element for a wide array of digital systems. Its primary applications include data storage registers, frequency dividers, and shift registers in computing and communication equipment. It is also commonly used in control logic circuits, simple state machines, and signal synchronization modules across industrial automation, consumer electronics, and automotive control units. Furthermore, it serves effectively in debouncing circuits for switches and creating toggle functions from momentary inputs.
