74AHCT126 QUADRUPLE 3-STATE BUFFERS OE HIGH Description Pin Assignments The 74AHCT126 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 4.5V to 5.5V. Features Wide Supply Voltage Range from 4.5V to 5.5V Inputs Are TTL Voltage Level Compatible Outputs Sink or Source 8mA at VCC = 4.5V CMOS Low Power Consumption Schmitt Trigger Action at All Inputs ESD Protection Exceeds JESD 22 200-V Machine Model (A115) 2000-V Human Body Model (A114) Applications Exceeds 1000-V Charged Device Model (C101) General Purpose Logic Latch-Up Exceeds 250mA per JESD 78, Class II Wide Array of Products Such as: Range of Package Options SO-14 and TSSOP-14 PCs, Networking, Notebooks, Netbooks Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Computer Peripherals, Hard Drives, CD/DVD ROMs Halogen and Antimony Free.
