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 75k pull-down resistors.

Notes:
1. VEE = 4.2V to 5.5V unless otherwise specified; VCC = VCCA = GND
2. ts is the minimum time before the transition of the clock that information
must be present at the data input.
3. tH is the minimum time after the transition of the clock that information must
remain unchanged at the data input.
