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
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please
email any questions regarding the system integration to Fairchild_questions@onsemi.com.

Description
The NC7SZ34 is a single buffer from Fairchild’s Ultra-
High Speed (UHS) series of TinyLogic®. The device is
fabricated with advanced CMOS technology to achieve
ultra-high speed with high output drive, while
maintaining low static power dissipation over a broad
VCC operating range of 1.65V to 5.5V VCC. The inputs
and output are high-impedance when VCC is 0V. Inputs
tolerate voltages up to 7V, independent of VCC operating
voltage.

Note:
2. CPD is defined as the value of the internal equivalent capacitance derived from dynamic operating current
consumption (ICCD) at no output lading and operating at 50% duty cycle. CPD is related to ICCD dynamic operating
current by the expression: ICCD=(CPD)(VCC)(fIN)+(ICCstatic).
