SEMICONDUCTOR TECHNICAL DATA

9 Bit Hold Register

The MC10E/100E143 is a 9-bit holding register, designed with byte-parity applications in mind. The E143 holds current data or loads new data, with the nine inputs D0 ± D8 accepting parallel input data.

•700MHz Min. Operating Frequency

•9-Bit for Byte-Parity Applications

•Asynchronous Master Reset

•Dual Clocks

•Extended 100E VEE Range of ± 4.2V to ± 5.46V

•75kΩ Input Pulldown Resistors

9-BIT HOLD REGISTER

The SEL (Select) input pin is used to switch between the two modes of operation Ð HOLD and LOAD. Input data is accepted by the registers a set-up time before the positive going edge of CLK1 or CLK2. A HIGH on the Master Reset pin (MR) asynchronously resets all the registers to zero.
