NEW PRODUCT 74LVC540A OCTAL BUFFER/ LINE DRIVER WITH 3 STATE OUTPUTS Description The 74LVC540A is an octal inverting buffer/driver is designed for driving bus lines or buffer memory address registers. The 3-state control gate is a 2-input AND gate with active-low inputs so that, if either output enable (OE1 or OE2) input is high, all eight outputs are in the high-impedance state..These devices feature inputs and outputs on opposite sides of the package that facilitate printed circuit board lay.

NEW PRODUCT 74LVC540A OCTAL BUFFER/ LINE DRIVER WITH 3 STATE OUTPUTS Description The 74LVC540A is an octal inverting buffer/driver is designed for driving bus lines or buffer memory address registers. The 3-state control gate is a 2-input AND gate with active-low inputs so that, if either output enable (OE1 or OE2) input is high, all eight outputs are in the high-impedance state..These devices feature inputs and outputs on opposite sides of the package that facilitate printed circuit board layout. 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. Features • Supply Voltage Range from 1.65V to 3.6V • Sinks or Sources 24mA at VCC = 3V • CMOS Low Power Consumption • IOFF Supports Partial Power Down Operation • Inputs or Outputs Accept Up to 5.5V • Inputs Can Be Driven by 3.3V or 5V Allowing for Mixed Voltage Applications • Schmitt Trigger Action at All Inputs • Typical VOLP (Quiet Output Ground Bounce) Less Than 0.8V with VCC = 3.3V and TA = +25°C • Typical VOHV (Quiet Output dynamic VOH) Greater than 2.0V with VCC = 3.3V and TA = +25°C • ESD Protection Tested per JESD 22 ƒ Exceeds 200-V Machine Model (A115) ƒ Exceeds 2000-V Human Body Model (A114) ƒ Exceeds 1000-V Charged Device Model (C101) • Latch-Up Exceeds 250mA per JESD 78, Class I • All devices are: ƒ Totally Lead-Free & Fully RoHS compliant (Notes 1 & 2) ƒ Halogen and Antimony Free. “Green” Device (Note 3) Pin Assignments Applications • General Purpose Logic • Bus Driving • Power Down Signal Isolation • Wide array of products such as: ƒ PCs, Notebooks, Netbooks, Ultrabooks ƒ Networking Computer Peripherals, Hard Drives, CD/DVD ROM ƒ 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. See http://www.diodes.com/quality/lead_free.html 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. 74LVC540A Document number: DS35890 Rev. 1 - 2 1 of 10 www.diodes.com July 2014 © Diodes Incorporated NEW PRODUCT 74LVC540A Ordering Information 74 LVC 540A xxx -13 Logic Device 74 : Logic Prefix 540 : Function Octal Buffer/Line Driver with 3 State Outputs Package T20 : TSSOP-20 Q20 : QFN-20 Packing -13 : 13” Tape & Reel Part Number 74LVC540AT20-13 74LVC540AQ20-13 Package Code T20 Q20 Package (Note 4 & 5) TSSOP-20 V-QFN4525-20 Package Size 6.4mm X 6.5mm X 1.2mm 0.65 mm lead pitch 2.5mm X 4.5mm X 0.95mm 0.50 mm lead pitch 13” Tape and Reel Quantity Part Number Suffix 2500/.
