Package: DIP, SOP, SOIC 16 Pin type

Manufacturer: Fairchild Semiconductor


74F109 datasheet



The 74F109 consists of two high-speed, completely independent transition clocked JKflip-flops. The clocking operationis independent of rise and fall times of the clock waveform.
The JKdesign allows operation as a D-type flip-flop (referto F74 data sheet) by connecting the J and Kinputs.

Asynchronous Inputs :

1. LOW input to SD sets Q to HIGH level

2. LOW input to CD sets Q to LOW level

3. Clear and Set are independent of clock

4. Simultaneous LOW on CD and SD makes both Q and Q HIGH

Absolute Maximum Ratings :

1. Storage Temperature : – 65°C to +150°C

2. Ambient Temperature under Bias : – 55°C to +125°C

3. Junction Temperature under Bias : – 55°C to +175°C

4. VCC Pin Potential to Ground Pin : – 0.5V to +7.0V

5. Input Voltage (Note 2) : – 0.5V to +7.0V

6. Input Current (Note 2) : -30 mA to +5.0 mA
