NC7SZD384
TinyLogic UHS 1-Bit Low Power Bus Switch
with Level Shifting
General Description
The NC7SZD384 provides 1-bit of high-speed CMOS TTL-
compatible bus switch. The low on resistance of the switch
allows inputs to be connected to outputs with minimal prop-
agation 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. Reduced voltage drive to the
gate of the FET switch permits nominal level shifting of 5V
to 3.3V through the switch.
