Frequently Asked Questions
What is the primary function of the NC7SZD384?
It provides 1-bit of high-speed CMOS TTL-compatible bus switching, connecting Port A to Port B.
How is the switch controlled and what happens when it's disabled?
The 'OE' (Bus Switch Enable) input controls it. When OE is HIGH, the switch is opened, creating a high-impedance state.
What types of packages are available for this component?
It is available in SOT23 and SC70 5-lead packages, as well as MicroPak.
Is this device suitable for level shifting applications?
Yes, it supports nominal level shifting from 5V down to 3.3V due to its low Icc voltage drive to the gate of the FET switch.
