3.3 V / 5 V ECL 9-Bit Shift
Register
The MC10EP/100EP142 is a 9−bit shift register, designed with
byte-parity applications in mind. The MC10/100EP142 is capable of
performing serial/parallel data into serial/parallel out and shifting in
only one direction. The nine inputs D0 − D8 accept parallel input data,
while S−IN accepts serial input data. The QT0:87 outputs do not need
to be terminated for the shift operation to function. To minimize
power, any Q output not used should be left unterminated.
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 CLK0 or CLK1; shifting is also accomplished
on the positive clock edge. A HIGH on the Master Reset pin (MR)
asynchronously resets all the registers to zero, overriding CLK0 and
CLK1 inputs.
The 100 Series contains temperature compensation.
