MOTOROLA SEMICONDUCTOR TECHNICAL DATA 9ĆBit 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 The SEL (Select) input pin is used to switch between the two modes of operation — HOLD and LOAD.
Input data is accepted by the registers a set-up time before the positive going edge of CLK1 or CLK2.
