TC74ACT74P,TC74ACT74F,TC74ACT74FT is an ultra-high speed CMOS D-type dual D-type flip-flop produced by Toshiba, which has the characteristics of low power consumption, high frequency, and high output current. It can be connected to TTL level.
The TC74ACT74 family provides a dual D‑type flip‑flop with asynchronous preset and clear inputs. It operates at TTL input levels, includes input protection diodes, and is pin‑compatible with the 74F74. The device is offered in DIP14, SOP14, and TSSOP14 packages.
Electrical specifications include a maximum supply voltage of –0.5 V to 7.0 V, a recommended operating range of 4.5 V to 5.5 V, high‑speed operation up to 180 MHz, low standby current (4 nA), and output drive capability of 24 mA. Propagation delays are typically 6–10 ns, and package masses range from 0.06 g to 0.96 g. This manual is written in Japanese.
