Revised January 2001 74LCX06 Low Voltage Hex Inverter/Buffer with Open Drain Outputs General Description Features The LCX06 contains six inverters/buffers. The inputs tolerate voltages up to 7V allowing the interface of 5V systems to 3V systems. ■ 5V tolerant inputs The outputs of the LCX06 are open drain and can be connected to other open drain outputs to implement active LOW wire AND or active HIGH wire OR functions. The 74LCX06 is fabricated with advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation. ■ 2.3V–3.6V VCC specifications provided ■ 3.7 ns tPD max (VCC = 3.3V), 10 µA ICC max ■ Power down high impedance inputs and outputs ■ ±24 mA output drive (VCC = 3.0V) ■ Implements patented noise/EMI reduction circuitry ■ Latch-up performance exceeds 500 mA ■ Functionally compatible with 74 series 05 ■ ESD performance: Human body model > 2000V Machine model > 200V Ordering Code: Order Number Package Number 74LCX06M 74LCX06SJ 74LCX06MTC M14A M14D MTC14 Package Description 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150 Narrow 14-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 14-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide Devices also available in Tape and Reel.

The device should 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. Note 2: IO Absolute Maximum Rating must be observed. Note 3: Unused inputs must be held HIGH or LOW. They may not float.
