DUAL JK NEGATIVE EDGE-TRIGGERED FLIP-FLOP
The MC74AC113/74ACT113 consists of two high-speed completely independent transition clocked JK flip-flops. The clocking operation is independent of rise and fall times of the clock waveform. The JK design allows operation as a D flip-flop (refer to MC74AC74/74ACT74 data sheet) by connecting the J and K inputs together. Asynchronous Inputs: LOW input to SD (Set) sets Q to HIGH level Set is independent of clock Outputs Source/Sink 24 m A ′ACT113 Has TTL Compatible Inputs

Frequently Asked Questions
How can I operate the device as a D flip-flop?
Connect the J and K inputs together to allow operation as a D flip-flop.
What is the recommended operating temperature range for this device?
The typical extended junction temperature (J T) range is –40 °C to 85 °C, while the storage temperature range is –65 to +150 °C.
What are the electrical specifications for the DC supply voltage and current output?
The recommended V CC DC Supply Voltage is 5.0V (Range: 4.5V to 5.5V). Output currents can sink/source up to ±24 mA.
Does this flip-flop only operate in one mode or multiple modes?
It supports three operating modes: Hold, Toggle, and Set/Load via asynchronous inputs (S for Set, L for Load).
