MOTOROLA MC10E167/MC100E167 handbook(1)
Datasheet
The MC10E/100E167 contains six 2:1 multiplexers followed by D flip-flops with single-ended outputs. Input data are selected by the Select control, SEL. The selected data are transferred to the flip-flop outputs by a positive edge on CLK1 or CLK2 (or both). A HIGH on the Master Reset (MR) pin asynchronously forces all Q outputs LOW.
