description

The 107 contain two independent JK flip-flops with

individual JK, clock, and direct clear inputs. The ‘107

is a positive pulse-triggered flip-flop. The J-K input data

is loaded into the master while the clock is high and

transferred to the slave and the outputs on the high-to-

low clock transistion. For these devices the J and K inputs

must be stable while the clock is high.

The 'LS107A contain two independent negative-edge-

triggered flip-flops. The J and K inputs must be stable

prior to the high-to-low clock transition for predictable

operation. When the clear is low, it overrides the clock

and data inputs forcing the Q output low and the Q

output high.

The SN54107 and the SN54LS107A are characterized

for operation over the full military temperature range of

~55°C to 125°C. The SN74107 and the SN74LS107A

are characterized for operation from 0°C to 70°C.
