NOT RECOMMENDED FOR NEW DESIGNS SY10E155 SY100E155 FINAL 6-BIT 2:1 MUX-LATCH FEATURES DESCRIPTION The SY10/100E155 offer six 2:1 multiplexers followed by latches with single-ended outputs, designed for use in new, high-performance ECL systems. The two external latch-enable signals (LEN 1 and LEN2) are gated through a logical OR operation before use as control for the six latches. When both LEN1 and LEN 2 are at a logic LOW, the latches are transparent, thus presenting the data from the multiplexers at the output pins. If either LEN 1 or LEN2 (or both) are at a logic HIGH, the outputs are latched. The multiplexer operation is controlled by the SEL (Select) signal which selects one of the two bits of input data at each mux to be passed through. The MR (Master Reset) signal operates asynchronously to take all outputs to a logic LOW. 750ps max. LEN to output Extended 100E VEE range of –4.2V to –5.5V 700ps max.
