74LVC240A SINGLE 2 INPUT POSITIVE NAND GATE Description Pin Assignments The 74LVC240A provides two 4-bit buffers/drivers with separate 1 20 2A1 11 the high-impedance state. GND 10 1OE from the A inputs to the Y outputs. When OE is high, the outputs are in Vcc output-enable (OE) inputs. When OE is low, the device passes data The device is designed for operation with a power supply range of NEW PRODUCT 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 24 ma at VCC = 3V • • CMOS Low Power Consumption IOFF Supports Partial -Power Down Operation • General Purpose Logic • Inputs or Outputs Accept up to 5.5V • Bus Driving • Inputs Can Be Driven by 3.3V or 5V Allowing for Mixed Voltage • Power Down Signal Isolation Applications • Wide Array of Products Such as: • • 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 • PCs, Notebooks, Netbooks, Ultrabooks Networking Computer Peripherals, Hard Drives, CD/DVD ROM Typical VOHV (Quiet Output dynamic VOH) Greater than 2.0V with TV, DVD, DVR, Set Top Box VCC = 3.3V and TA = +25°C • • • ESD Protection Tested per JESD 22 Exceeds 200-V Machine Model (A115) Exceeds 2000-V Human Body Model (A114) Exceeds 1000-V Charged Device Model (C101) Latch-Up Exceeds 250mA per JESD 78, Class I All devices are: Totally Lead-Free & Fully RoHS compliant (Notes 1 & 2) Halogen and Antimony Free.“Green” Device (Note 3) Notes: 1.
