Low Voltage Triple 3-Input NAND Gate

with 5V Tolerant Inputs

74LCX10 Low Voltage Triple 3-Input NAND Gate with 5V Tolerant Inputs

June 2000
Revised February 2005

General Description

The LCX10 contains three 3-inp ut N AN D gate s. Th e i npu ts
tolerate voltages up to 7V allowing th e inter face of 5 V sys­tems to 3V systems.

The 74LCX10 is fabrica ted with advanced C MOS technol­ogy to achieve high speed operation while maintaining
CMOS low power dissipation.

Note 1: The Absolute Maximum Ratings are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated
at these limits. The parametric va lues defin ed in the El ectrical C haracteris tics tables are not guara nteed at the Absolute M aximum Ratings. The “Recom-
mended Operat ing Conditions” table will define the conditions fo r ac t ual device operation.
