NTE4027B & NTE4027BT
Integrated Circuit
CMOS, Dual J−K Flip−Flop
Description:
The NTE4027B (16−Lead DIP) and NTE4027BT (SOIC−16) dual J−K flip−flops have 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.
Features:
D Diode Protection on All Inputs
D Supply Voltage Range: 3Vdc to 18Vdc
D Logic Swing Independent of Fanout
D 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 o the Clock Pulse
D Capable of Driving Two Low−Power TTL Loads or One Low−Power Schottky TTL Load Over
the Rated Temperature Range
