74LVC125A QUADRUPLE 3-STATE BUFFERS Description Pin Assignments The 74LVC125A provides four independent buffers with three state outputs. Each output is independently controlled by an associated output enable pin (OE) which places the device in the high impedance state when driven high. 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. Features • Supply Voltage Range from 1.65V to 5.5V • 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 • Voltage Level Shifting • Inputs can be driven by 3.3V or 5.5V allowing for voltage • General Purpose Logic translation applications. • Power Down Signal Isolation ESD Protection Exceeds JESD 22 • • Applications Wide array of products such as: 200-V Machine Model (A115-A) 2000-V Human Body Model (A114-A) Computer peripherals, hard drives, CD/DVD ROM Exceeds 1000-V Charged Device Model (C101C) TV, DVD, DVR, set top box • Latch-Up Exceeds 250mA per JESD 78, Class II • 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) PCs, networking, notebooks, ultrabooks, netbooks Notes: 1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant. 2. See http://www.diodes.com for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green" and Lead-free. 3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and <1000ppm antimony compounds. 74LVC125A Document number: DS35265 Rev. 3 - 2 1 of 10 www.diodes.com July 2012 © Diodes Incorporated 74LVC125A Pin Descriptions Pin Number Pin Name Description 1 1OE 2 1A Data Input 3 1Y Data Output 4 2OE 5 2A Data Input 6 2Y Data Output 7 GND 8 3Y Data Output 9 3A Data Input 10 3OE 11 4Y Data Outp 12 4A Data Input 13 4OE Data Enable Input (active low) 14 VCC Supply Voltage Data Enable Input (active low) Data Enable Input (active low) Ground Data Enable Input (active low) Logic Diagram Function Table Inputs Output OE A Y L H H L L L H X Z 74LVC125A Document number: DS35265 Rev. 3 - 2 2 of 10 www.diodes.com July 2012 © Diodes Incorporated 74LVC125A Absolute Maximum Ratings (Note 4) (@TA = +25°C, unless otherwise specified.)
