74LVC1G34 SINGLE BUFFER GATE Description Pin Assignments The 74LVC1G34 is a single buffer gate with a standard push-pull ( Top View ) ( Top View ) output. 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 NC 1 5 Vcc NC 1 5 Vcc device to be used in a mixed voltage environment. The device is fully A 2 specified for partial power down applications using I . The I OFF OFF A 2 3 4 Y circuitry disables the output preventing damaging current backflow GND when the device is powered down. GND 4 Y SOT553 3 (Top View) The gate performs the positive Boolean function: SOT25 / SOT353 1 NC 6 Vcc A 2 5 NC Y = A ( Top View ) GND 3 4 Y 8 Vcc NC 1 X1-DFN1010-6 (Type B) A 2 5 NC (Top View) GND 4 Y 3 1 6 NC Vcc 2 5 A NC X2-DFN1410-6 3 4 GND Y ( Bottom View ) X2-DFN1010-6 GND 3 4 Y (Top View) A 2 5 NC NC 1 Vcc 5 3 NC 1 6 Vcc GND X2-DFN1409-6 A 2 4 Y Chip Scale X2-DFN0808-4 Features Alternative Packages not to scale Wide Supply Voltage Range from 1.65 to 5.5V 24mA Output Drive at 3.3V CMOS Low Power Consumption Applications I Supports Partial-Power-Down Mode Operation OFF Voltage Level Shifting Inputs Accept Up to 5.5V General Purpose Logic ESD Protection Tested per JESD 22 Power Down Signal Isolation Exceeds 200-V Machine Model (A115) Wide array of products such as: Exceeds 2000-V Human Body Model (A114) PCs, Networking, Notebooks, Netbooks, PDAs Exceeds 1000-V Charged Device Model (C101) Tablet Computers, E-Readers Latch-Up Exceeds 100mA per JESD 78, Class I Computer Peripherals, Hard Drives, CD/DVD ROMs Range of Package Options TVs, DVDs, DVRs, Set-Top Boxes Direct Interface with TTL Levels Cell Phones, Personal Navigation / GPS Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) MP3 Players, Cameras, Video Recorders Halogen and Antimony Free.
