Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated

NC7SZ384
1-Bit Low Power Bus Switch
General Description
The NC7SZ384 provides 1-bit of ultra high-speed CMOS TTLcompatible 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 connected to Port B. When OE is HIGH, the switch is open
and a high-impedance state exists between the two ports.
Features
O Space saving SOT23 or SC70 5-lead package
O Ultra small MicroPak¥ leadless package
O 5: switch connection between two ports
O Minimal propagation delay through the switch
O Low ICC
O Zero bounce in flow-through mode
O Control inputs compatible with TTL level
