TC74LCX273F/FT/FK is a low voltage (3.3V) driven CMOS 8 bit D type flip-flop produced by Toshiba. It has the characteristics of low power consumption and high speed. The trigger can tolerate 5.5V input signal and is suitable for 3.3V and 5V dual power systems.
The TC74LCX273F/FT/FK is a low‑voltage octal D‑type flip‑flop with clear, designed for 5 V tolerant inputs and outputs. It operates from 1.65 V to 3.6 V supply and supports both 3.3 V and 5 V system interfaces.
The document provides absolute maximum ratings, detailed DC and AC electrical characteristics, pin‑connection diagrams, truth tables, and mechanical drawings for three package types (SOP20, TSSOP20, VSSOP20). It also includes handling guidelines and reliability notes for designers. This manual is written in Japanese.
