The 74LCX74 is a Low Voltage Dual D-Type Positive Edge-Triggered Flip-Flop with 5V Tolerant Inputs manufactured by Fairchild Semiconductor Corporation
The 74LCX74 is a dual D‑type flip‑flop featuring asynchronous Set and Clear inputs, complementary Q and Q̅ outputs, and 5 V tolerant inputs. Information is transferred on the positive edge of the clock pulse, with the data input locked out after the threshold is passed.
The device operates from a 2.0 V to 3.6 V supply, provides up to +24 mA output drive, and meets stringent ESD specifications (human‑body model >2000 V, machine model >200 V). Physical packages include SOIC‑14, SOP‑14, and TSSOP‑14 with detailed land‑pattern recommendations.
