Description
The 74HCT74D,653 is a high-speed, silicon-gate CMOS Dual D-Type Flip-Flop featuring individual asynchronous Set (preset) and Reset (clear) inputs. This device is designed for edge-triggered operation, capturing data from the D input on the positive-going edge of the clock signal. Each of the two flip-flops operates independently, making this IC highly versatile for sequential logic, frequency division, and data synchronization.
As part of the HCT series, this device is engineered with TTL-compatible input levels, allowing it to interface directly with 5V TTL logic systems while maintaining the low power consumption and high noise immunity characteristic of the CMOS logic family. The SOIC-14 surface-mount package is optimized for space-efficient PCB designs and reliable automated assembly.
