DESCRIPTION
The AZ10/100E142 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.
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 registers to zero.
NOTE: Specifications in ECL/PECL tables are valid when thermal equilibrium is established.
