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.
• SHIFT overrides HOLD/LOAD Control
