MM74C73 • MM74C76
Dual J-K Flip-Flops with Clear and Preset
General Description
Features
The MM74C73 and MM74C76 dual J-K flip-flops are mono-
lithic complementary MOS (CMOS) integrated circuits con-
structed with N- and P-channel enhancement transistors.
Each flip-flop has independent J, K, clock and clear inputs
and Q and Q outputs. The MM74C76 flip flops also include
preset inputs and are supplied in 16 pin packages. This
flip-flop is edge sensitive to the clock input and change
state on the negative going transition of the clock pulse.
Clear or preset is independent of the clock and is accom-
plished by a low level on the respective input.
■ Supply voltage range: 3V to 15V
■ Tenth power TTL compatible: Drive 2 LPTTL loads
■ High noise immunity: 0.45 VCC (typ.)
■ Low power: 50 nW (typ.)
■ Medium speed operation: 10 MHz (typ.)

Note 2: “Absolute Maximum Ratings” are those values beyond which the
safety of the device cannot be guaranteed. Except for “Operating Tempera-
ture Range” they are not meant to imply that the devices should be oper-
ated at these limits. The table of Electrical Characteristics provides
conditions for actual device operation.
