SEMICONDUCTOR TECHNICAL DATA
3ĆBit Differential FlipĆFlop
The MC10E/100E431 is a 3-bit flip-flop with differential clock, data
input and data output.
The asynchronous Set and Reset controls are edge-triggered rather
than level controlled. This allows the user to rapidly set or reset the
flip-flop and then continue clocking at the next clock edge, without the
necessity of de-asserting the set/reset signal (as would be the case with a
level controlled set/reset).
The E431 is also designed with larger internal swings, an approach
intended to minimize the time spent crossing the threshold region and
thus reduce the metastability susceptibility window.
The differential input structures are clamped so that the inputs of
unused registers can be left open without upsetting the bias network of
the device. The clamping action will assert the D and the CLK sides of the
inputs. Because of the edge triggered flip-flop nature of the device
simultaneously opening both the clock and data inputs will result in an
output which reaches an unidentified but valid state. Note that the input
clamps only operate when both inputs fall to 2.5V below VCC.
