NC7SZD384
1-Bit Low Power Bus Switch with Level Shifting
General Description
The NC7SZD384 provides 1-bit of high-speed CMOS TTL-com-
patible bus switch. The low on resistance of the switch allows
inputs to be connected to outputs with minimal propagation
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 con-
nected 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.
