SY100S355JZTR

QUAD MULTIPLEXER/LATCH

DESCRIPTION

The SY100S355 offers four transparent latches with differential outputs and is designed for use in high performance ECL systems. The Select inputs S0, S1 select one of the two sources of input data D0 or D1 to the latch. The Select inputs can also force the outputs to a logic LOW when the latch is in the transparent mode. The latches are in the transparent mode when both Enables E1, E2 are at a logic LOW state. In the transparent mode, the Select inputs can pass an input logic HIGH from D0 or D1 to the output.

If the Select inputs are tied together, then input data from either D0 or D1 is always passed through. A rising edge on either Enable input will latch the outputs with the most recent data at the latch inputs being stored. The Master Reset MR input overrides all other inputs and takes the Q outputs to a logic LOW. The inputs on this device have 75kΩ pull-down resistors.
