74LVC2G34 DUAL BUFFER Description Pin Assignments The 74LVC2G34 is a dual buffer gate with standard push pull outputs. The device is designed for operation with a power supply range of 1.65V to 5.5V. The inputs are tolerant to 5.5V allowing this device to be used in a mixed voltage NEW PRODUCT environment. The device is fully specified for partial power down applications using IOFF. The IOFF circuitry disables the output preventing damaging current backflow when the device is powered down. The gate performs the positive Boolean function: Y=A Features Applications * Wide Supply Voltage Range from 1.65V to 5.5V * Voltage Level Shifting * 24mA Output Drive at 3.0V * General Purpose Logic * CMOS low power consumption * Power Down Signal Isolation * IOFF Supports Partial-Power-Down Mode Operation * * Inputs accept up to 5.5V o PCs, networking, notebooks, netbooks, PDAs ESD Protection Tested per JESD 22 * o Computer peripherals, hard drives, CD/DVD ROM o Exceeds 200-V Machine Model (A115-A) o TV, DVD, DVR, set top box o Exceeds 2000-V Human Body Model (A114-A) o Cell Phones, Personal Navigation / GPS o Exceeds 1000-V Charged Device Model (C101) o MP3 players ,Cameras, Video Recorders * Latch-Up Exceeds 100mA per JESD 78, Class II * Range of Package Options * Wide array of products such as: SOT26, SOT363, DFN1410, and DFN1010 Available in "Green" Molding Compound (no Br, Sb) * Lead Free Finish/ RoHS Compliant (Note 1) Notes: 1.
