Quad Bus Receiver
as well as levels compatible with IBM–type buses. The clock, strobe, and reset
inputs accept MECL 10,000 logic levels.
yield temporary latch storage of the information after receiving it from the bus.
The outputs can be strobed to allow accurate synchronization of signals and/or
connection to MECL 10,000 level buses. When the clock is low, and the reset
input is disabled, the outputs will follow the D inputs. The latches will store the
data on the rising edge of the clock. The outputs are enabled when the strobe
input is high. Unused D inputs must be tied to V CC or Gnd. The clock, strobe,
and reset inputs each have 50 k ohm pulldown resistors to V EE . They may be
left floating, if not used.
by tying the hysteresis control input to V EE . In this mode, the input threshold
points of the D inputs are fixed. The second mode is obtained by tying the
hysteresis control input to ground. In this mode, input hysteresis is achieved as
shown in the test table. This hysteresis is desirable where extra noise margin is
required on the D inputs. The outer input pins are unaffected by the mode of
operation used.
