74HCT125 QUADRUPLE 3-STATE BUFFERS OE LOW Description Pin Assignments The 74HCT125 provides provides four independent buffer gates with ( Top View ) 3-state outputs. Each buffer has a separate enable pin that if driven with a high logic level places the corresponding output in the high 1 14 1OE Vcc impedance state. The device is designed for operation with a power 2 13 1A 4OE supply range of 4.5V to 5.5V. 3 12 1Y 4A 4 11 2OE 4Y Features 5 10 2A 3OE Wide Supply Voltage Range from 4.5V to 5.5V 6 9 2Y 3A Pin Compatible with Low Power Schottky (LSTTL) 7 Inputs Are TTL Voltage Level Compatible 8 3Y GND Sinks or Sources 4mA at V = 4.5V CC SO-14 / TSSOP-14 CMOS Low Power Consumption Schmitt Trigger Action at All Inputs Applications ESD Protection Exceeds JESD 22 200-V Machine Model (A115-A) General Purpose Logic 2000-V Human Body Model (A114-A) Wide array of products such as: Exceeds 1000-V Charged Device Model (C101C) PCs, networking, notebooks, netbooks Range of Package Options SO-14 and TSSOP-14 Computer peripherals, hard drives, CD/DVD ROM Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) TV, DVD, DVR, set top box Halogen and Antimony Free.
