74LCX06
Low Voltage Hex Inve rte r/Buffer w ith Open Drain Outputs

74LCX06 Low Voltage Hex Inverter/Buffer with Open Drain Outputs

October 1999
Revised February 2005

General Description

The LCX06 contains six inverters/b uffers. The inputs tole r­ate voltages up to 7V allowing the interface of 5V syste ms
to 3V systems.

The outputs of the LCX06 are open drain an d can be con­nected to other open drain outputs to implement active
LOW wire AND or active HIGH wire OR functions.

The 74LCX06 is fabrica ted with advanced C MOS technol­ogy to achieve high speed operation while maintaining
CMOS low power dissipation.

Features

■ 5V tolerant inputs

■ 2.3V–3.6V V

■ 3.7 ns t

Note 2: 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.
