DESCRIPTION
The SY10/100E156 offer three 4:1 multiplexers followed by latches with differential outputs, designed for use in new, high-performance ECL systems. The two external latch enable signals (LEN1 and LEN2) are gated through a logical OR operation before use as control for the three latches. When both LEN1 and LEN2 are at a logic LOW, the latches are transparent, thus presenting the data from the multiplexers at the output pins. If either LEN1 or LEN2 (or both) are at a logic HIGH, the outputs are latched.
