DESCRIPTION:
dual metal CMOS technology. These high-speed, low-power devices are
organized as two independent 8-bit bus transceivers with 3-state D-type
registers. For example, the xOEAB and xOEBA signals control the transceiver
functions.
stored data transfer. The circuitry used for select control will eliminate the typical
decoding glitch that occurs in a multiplexer during the transition between stored
and real time data. A low input level selects real-time data and a high level selects
stored data.
by low-to-high transitions at the appropriate clock pins (xCLKAB or xCLKBA),
regardless of the select or enable control pins. Flow-through organization of
signal pins simplifies layout. All inputs are designed with hysteresis for improved
noise margin.

capability to allow "live insertion" of boards when used as backplane drivers.
