BLOCK DIAGRAM
DESCRIPTION
The SY10/100E167 offer six 2:1 multiplexers followed
by D flip-flops with single-ended outputs, designed for use
in new, high-performance ECL systems. The Select (SEL)
control allows one of the two data inputs to the multiplexer
to pass through. The two external clock signals (CLK1,
CLK2) are gated through a logical OR operation before use
as control for the six flip-flops. The selected data are
transferred to the flip-flops on the rising edge of CLK1 or
CLK2 (or both).
The multiplexer operation is controlled by the Select
(SEL) signal which selects one of the two bits of input data
at each mux to be passed through.
When a logic HIGH is applied to the Master Reset (MR)
signal, it operates asychronously to take all outputs Q to a
logic LOW.
