54LVX3384
10-Bit Low Power Bus Switch
General Description
The 54LVX3384 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 add-
ing propagation delay or generating additional ground
bounce noise. The device is organized as two 5-bit switches
with separate bus enable (OE ) signals. When OE is low, the
switch is on and port A is connected to port B. When OE is
high, the switch is open and a high-impedance state exists
between the two ports.
Features
