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.

Stresses exceeding those listed in the Maximum Ratings table may damage the
device. If any of these limits are exceeded, device functionality should not be
assumed, damage may occur and reliability may be affected.
1. Temperature Derating: “D/DW” Packages: –7.0 mW/_C From 65_C To 125_C
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
