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
n 4Ω switch connection between two ports
n Minimal propagation delay through the switch
n Ultra low power with <0.1 µA typical I_CC
n Zero ground bounce in flow-through mode
n Control inputs compatible with TTL levels
n Available in CDIP and Cerpack Packaging
n Standard Microcircuit Drawing (SMD) 5962-9950701
