74LVC1G34

SINGLE BUFFER GATE

Description		Pin Assignments

The 74LVC1G34 is a single buffer gate with a standard push-pull 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 device to be used in a mixed voltage 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

•Wide Supply Voltage Range from 1.65 to 5.5V

•± 24mA Output Drive at 3.3V

•CMOS Low Power Consumption

•IOFF Supports Partial-Power-Down Mode Operation

•Inputs Accept Up to 5.5V

•ESD Protection Tested per JESD 22

Exceeds 200-V Machine Model (A115)

Exceeds 2000-V Human Body Model (A114)

Exceeds 1000-V Charged Device Model (C101)

•Latch-Up Exceeds 100mA per JESD 78, Class I

•Range of Package Options

•Direct Interface with TTL Levels

•Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)

•Halogen and Antimony Free. “Green” Device (Note 3)

Applications

•Voltage Level Shifting

•General Purpose Logic

•Power Down Signal Isolation

•Wide array of products such as:

PCs, Networking, Notebooks, Netbooks, PDAs

Tablet Computers, E-Readers

Computer Peripherals, Hard Drives, CD/DVD ROMs

TVs, DVDs, DVRs, Set-Top Boxes

Cell Phones, Personal Navigation / GPS

MP3 Players, Cameras, Video Recorders

Notes:	1.	No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant.
