SEMICONDUCTOR TECHNICAL DATA
8ĆBit Scannable Register
The MC10E/100E241 is an 8-bit shiftable register. Unlike a standard
universal shift register such as the E141, the E241 features internal data
feedback organized so that the SHIFT control overrides the HOLD/LOAD
control. This enables the normal operations of HOLD and LOAD to be
toggled with a single control line without the need for external gating. It
also enables switching to scan mode with the single SHIFT control line.
The eight inputs D0 – D7 accept parallel input data, while S-IN accepts
serial input data when in shift mode. Data is accepted a set-up time
before the positive-going edge of CLK; shifting is also accomplished on
the positive clock edge. A HIGH on the Master Reset pin (MR)
asynchronously resets all the registers to zero.
