DESCRIPTION

The SY10/100E241 are 8-bit shiftable registers designed for use in new, high-performance ECL systems. Unlike the E141, the E241 features internal data feedback organized such that the SHIFT control overrides the HOLD, /LOAD control. Thus, the normal operations of HOLD and LOAD can be toggled with a single control line without the need for external gating. This configuration also enables switching to scan mode with the single SHIFT control line.
