The 74LVC32A provides four independent 2-input OR gates. The device is designed for operation with a power supply range of 1.65V to 3.6V. 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.


  • Supply Voltage Range from 1.65V to 3.6V 
  • Sinks 24mA at VCC = 3.3V 
  • CMOS low power consumption 
  • IOFF Supports Partial-Power-Down Mode Operation 
  • Inputs or outputs accept up to 5.5V 
  • Inputs can be driven by 3.3V or 5.5V allowing for voltage translation applications. 
  • ESD Protection Exceeds JESD 22
    • 200-V Machine Model (A115) 
    • 2000-V Human Body Model (A114) 
  • Latch-Up Exceeds 250mA per JESD 78, Class I 
  • Range of Package Options SO-14 and TSSOP-14
    • Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) 
    • Halogen and Antimony Free. “Green” Device (Note 3)


  • Voltage Level Shifting
  • General Purpose Logic
  • Power Down Signal Isolation
  • Wide array of products such as:
    • PCs, networking, notebooks, netbooks, PDAs
    • Computer peripherals, hard drives, CD/DVD ROM
    • TV, DVD, DVR, set top box
