MC14027B
Dual J-K Flip-Flop
The MC14027B dual J–K flip–flop has independent J, K, Clock (C),
Set (S) and Reset (R) inputs for each flip–flop. These devices may be
used in control, register, or toggle functions.
• Diode Protection on All Inputs
• Supply Voltage Range = 3.0 Vdc to 18 Vdc
• Logic Swing Independent of Fanout
• Logic Edge–Clocked Flip–Flop Design —
Logic state is retained indefinitely with clock level either high or low;
information is transferred to the output only on the positive–going
edge of the clock pulse
• Capable of Driving Two Low–power TTL Loads or One Low–power
Schottky TTL Load Over the Rated Temperature Range
• Pin–for–Pin Replacement for CD4027B

2. Maximum Ratings are those values beyond which damage to the device
may occur.
3. Temperature Derating:
Plastic “P and D/DW” Packages: – 7.0 mW/C From 65C To 125C
This device contains protection circuitry to guard against damage due to high
static voltages or electric fields. However, precautions must be taken to avoid
applications of any voltage higher than maximum rated voltages to this
high–impedance circuit. For proper operation, V

out
should be constrained
to the range V

Unused inputs must always be tied to an appropriate logic voltage level (e.g.,
either V

or V

). Unused outputs must be left open.
