MC74AC109/74ACT109 are two high-speed, completely independent transition clocked JK flip-flops
This document describes the MC74AC109 and MC74ACT109, which consist of two high-speed, completely independent, transition clocked JK flip-flops. The clocking operation is independent of the rise and fall times of the clock waveform. The JK design allows operation as a D flip-flop by connecting the J and K inputs together. Asynchronous inputs include Set (Sp) and Clear (Cp), which are independent of the clock.
| Outputs Source/Sink Current | 24 mA |
|---|---|
| Supply Voltage Range | -0.5 to +7.0 V |
| Operating Temperature Range | -40 to +85 °C |
| Maximum Clock Frequency (5.0V) | 150 MHz |
Yes, by connecting the J and K inputs together.
Both Q and Q outputs will be HIGH.
No, they are independent of the clock.
