DESCRIPTION:
dual metal CMOS technology. These high-speed, low-power devices are
organized as two independent 8-bit D-type latched transceivers with
separate input and output control to permit independent control of data flow
in either direction. For example, the A-to-B Enable (xCEAB) must be low
in order to enter data from the A port or to output data from the B port. xLEAB
controls the latch function. When xLEAB is low, the latches are transparent.
A subsequent low-to-high transition of xLEAB signal puts the A latches in
the storage mode. xOEAB performs output enable function on the B port.
Data flow from the B port to the A port is similar but requires using xCEBA,
xLEBA, and xOEBA inputs. Flow-through organization of signal pins
simplifies layout. All inputs are designed with hysteresis for improved noise
margin.
and low-impedance backplanes. The output buffers are designed with
power off disable capability to allow "live insertion" of boards when used
as backplane drivers.
