IN74HCT74AD中文资料IKSEMICON数据手册PDF规格书

The IN74HCT74A is identical in pinout to the LS/ALS74. This device may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. This device consists of two D flip-flops with individual Set, Reset, and Clock inputs. Information at a D-input is transferred to the corresponding Q output on the next positive going edge of the clock input. Both Q and Q outputs are available from each flip-flop. The Set and Reset inputs are

asynchronous.

• TTL/NMOS Compatible Input Levels

• Outputs Directly Interface to CMOS, NMOS, and TTL

• Operating Voltage Range: 4.5 to 5.5 V

• Low Input Current: 1.0 µA
