74HC126 QUADRUPLE 3-STATE BUFFERS OE HIGH Description Pin Assignments The 74HC126 provides provides four independent buffer gates with 3-state outputs. Each buffer has a separate enable pin that if driven with a low logic level places the corresponding output in the high impedance state. The device is designed for operation with a power supply range of 2.0V to 6.0V. Features Wide Supply Voltage Range from 2.0V to 6.0V Sinks or sources 4mA at V = 4.5V CC CMOS low power consumption Schmitt Trigger Action at All Inputs ESD Protection Exceeds JESD 22 200-V Machine Model (A115-A) 2000-V Human Body Model (A114-A) Exceeds 1000-V Charged Device Model (C101C) Applications Range of Package Options SO-14 and TSSOP-14 General Purpose Logic Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Wide array of products such as: Halogen and Antimony Free. Green Device (Note 3) PCs, Networking, Notebooks, Netbooks Computer Peripherals, Hard Drives, CD/DVD ROM TV, DVD, DVR, Set Top Box Notes: 1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant. 2.
