MC100E241 8-BIT SCANNABLE REGISTER

The MC100E241 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 ena.

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 th.
