DESCRIPTION:
dual metal CMOS technology.The LVCH16276A
bidirectional, 12-bit, registered, bus multiplexer for use in synchronous
memory interleaving applications. All registers have a common clock and
use a clock enable (CExxx) on each data register to control data sequenc-
ing. The output enables and mux select (OEA, OEB and SEL) are also
under synchronous control allowing direction changes to be edge trig-
gered events.
transferred between the A port and either/both of the B ports. The clock
enable (CE1B, CE2B, CEA1B and CEA2B) inputs control the data storage.
Both B ports have a common output enable (OEB) to aid in synchronously
loading the B registers from the B port.
devices. This feature allows the use of this device as a translator in a mixed
3.3V/5V supply system.
driver is capable of driving a moderate to heavy load while maintaining
speed performance.
whenever the input goes to a high impedance. This prevents floating inputs
and eliminates the need for pull-up/down resistors.
