NC7SZ384
1-Bit Low Power Bus Switch
November 1996
Revised December 2005
General Description
The NC7SZ384 provides 1-bit of ultra high-speed CMOS TTL-
compatible bus switch. The low On Resistance of the switch
allows inputs to be connected to outputs with minimal propaga-
tion delay and without generating additional ground bounce
noise. The device is organized as a 1-bit switch with a bus
enable (OE) signal. 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.
