74VCX38 Low Voltage Quad 2-Input NAND Gate with Open Drain Outputs and 3.6V Tolerant Inputs and Outputs

74VCX38
Low Voltage Quad 2-Input NAND Gate with Open Drain

Outputs and 3.6V Tolerant Inputs and Outputs

General Description

The VCX38 contains four 2-in put NAND gates with open
drain outputs. This product is designed for low voltage
(1.65V to 3.6V) V

CC

applications with I/O compatibility up
to 3.6V.
The VCX38 is fabricated with adv ance d CMOS techno logy

to achieve high-speed ope ration while maintai ning CMOS
low power dissipation.

Absolute Maximum Ratings(Note 1) Recommended Operating

Conditions

(Note 3)

Note 1: The “Absolute Maximum Ratin gs” are those v alues beyon d which
the safety of the dev ice cannot be guaranteed. T he device sh ould not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the Absolute Maximum Rat­ings. The “Recommended Operating Conditions” table will define the condi­tions for actual device operation.
