74LVX3L384
10-Bit Low Power Bus Switch
General Description
The LVX3L384 provides 10 bits of high-speed CMOS TTL-
compatible bus switches The low on resistance of the
switch allows inputs to be connected to outputs without
adding propagation delay or generating additional ground
bounce noise The device is organized as two 5-bit switches
with separate bus enable (BE) signals When BE is low the
switch is on and port A is connected to port B When BE is
high the switch is open and a high-impedance state exists
between the two ports
