74LVC2G34 DUAL BUFFERS Description Pin Assignments ( Top View ) The 74LVC2G34 is a dual buffer gate with standard push-pull outputs. ( Top View ) The device is designed for operation with a power supply range of 6 1A 1 1Y 1.65V to 5.5V. The inputs are tolerant to 5.5V allowing this device to 1A 1 6 1Y be used in a mixed voltage environment. The device is fully specified 2 5 Vcc GND Vcc GND 2 5 for partial power down applications using I . The I circuitry OFF OFF 3 4 2Y 2A disables the output preventing damaging current backflow when the 2A 2Y 3 4 device is powered down. X2-DFN1410-6 SOT26 / 363 The gate performs the positive Boolean function: (Top View) 1A 1 6 1Y Y A ( Bottom View ) 2 5 GND Vcc 3 2A 4 2Y 2A 3 4 2Y X1-DFN1010-6 GND 2 5 Vcc Features 1A 1 6 1Y ( Top View ) Wide Supply Voltage Range from 1.65V to 5.5V 1Y 1A 1 6 DFN1409 24mA Output Drive at 3.0V GND 2 5 Vcc Chip Scale CMOS Low Power Consumption 3 4 2A 2Y Alternative I Supports Partial-Power-Down Mode Operation OFF X2-DFN1010-6 Inputs Accept up to 5.5V ESD Protection Tested per JESD 22 Exceeds 200-V Machine Model (A115) Applications Exceeds 2000-V Human Body Model (A114) Exceeds 1000-V Charged Device Model (C101) Voltage Level Shifting Latch-Up Exceeds 100mA per JESD 78, Class I General Purpose Logic DFN1409 Package Designed as a Direct Replacement for Chip Power Down Signal Isolation Scale Packaging Wide Array of Products Such as: Range of Package Options SOT26, SOT363, X1-DFN1010-6, PCs, Networking, Notebooks, Netbooks, Tablets X2-DFN1010-6, X2-DFN1409-6, and X2-DFN1410-6 Computer Peripherals, Hard Drives, SSD, CD/DVD ROM Leadless Packages Named per JESD30E TV, DVD, DVR, Set Top Box Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Cell Phones, Personal Navigation / GPS Halogen and Antimony Free.
