Pinout

Pin Name Type Function
1 1RD input Asynchronous reset-direct input (active-LOW) for flip-flop 1.
2 1D input Data input for flip-flop 1; data that meets the set-up and hold times on the LOW-to-HIGH clock transition is stored and appears at nQ.
3 1CP input Clock input for flip-flop 1, LOW-to-HIGH edge-triggered.
4 1SD input Asynchronous set-direct input (active-LOW) for flip-flop 1.
5 1Q output True flip-flop output 1Q.
6 ~{1Q} output Complement flip-flop output 1Q (complement of 1Q).
7 GND power_in Ground (0 V).
8 ~{2Q} output Complement flip-flop output 2Q (complement of 2Q).
9 2Q output True flip-flop output 2Q.
10 2SD input Asynchronous set-direct input (active-LOW) for flip-flop 2.
11 2CP input Clock input for flip-flop 2, LOW-to-HIGH edge-triggered.
12 2D input Data input for flip-flop 2; data that meets the set-up and hold times on the LOW-to-HIGH clock transition is stored and appears at nQ.
13 2RD input Asynchronous reset-direct input (active-LOW) for flip-flop 2.
14 VCC power_in Supply voltage, specified from 1.0 V to 5.5 V in the recommended operating conditions.
