9ĆBit Shift Register
The MC10E/100E142 is a 9-bit shift register, designed with byte-parity
applications in mind. The E142 performs serial/parallel in and
serial/parallel out, shifting in one direction. The nine inputs D0 – D8
accept parallel input data, while S-IN accepts serial input data. The Qn
outputs do not need to be terminated for the shift operation to function. To
minimize noise and power, any Q output not used should be left
unterminated.

75kInput Pulldown Resistors
The SEL (Select) input pin is used to switch between the two modes of
operation — SHIFT and LOAD. The shift direction is from bit 0 to bit 8.
Input data is accepted by the registers a set-up time before the positive
going edge of CLK1 or CLK2; shifting is also accomplished on the positive
clock edge. A HIGH on the Master Reset pin (MR) asynchronously resets
all the resisters to zero.
