74LVCE1G126 SINGLE BUFFER GATE WITH 3-STATE OUTPUT Description Pin Assignments (Top View) The 74LVCE1G126 is a single non-inverting buffer/bus driver with a 3-state output. The output enters a high impedance 1 5 Vcc OE state when a LOW-level is applied to the output enable (OE) pin. The device is designed for operation with a power supply A 2 range of 1.4V to 5.5V. The inputs are tolerant to 5.5V allowing this device to be used in a mixed voltage 3 4 Y GND environment. The device is fully specified for partial power down applications using I . The I circuitry disables the OFF OFF SOT25 / SOT353 output preventing damaging current backflow when the device is powered down. (Top View) Features 6 OE 1 Vcc Extended Supply Voltage Range from 1.4 to 5.5V 2 A 5 NC Switching speed characterized for operation at 1.5V Offers 30% speed improvement over LVC at 1.8V. 4 GND 3 Y 24mA Output Drive at 3.3V CMOS low power consumption DFN1410 (Note 2) IOFF Supports Partial-Power-Down Mode Operation Inputs accept up to 5.5V ESD Protection Tested per JESD 22 Applications Exceeds 200-V Machine Model (A115-A) Exceeds 2000-V Human Body Model (A114-A) Voltage Level Shifting Latch-Up Exceeds 100mA per JESD 78, Class II Bus Driver / Repeater Range of Package Options Power Down Signal Isolation Direct Interface with TTL Levels General Purpose Logic SOT25, SOT353 and DFN1410: Assembled with Green Wide array of products such as. o PCs, networking, notebooks, netbooks, PDAs Molding Compound (no Br, Sb) o Computer peripherals, hard drives, CD/DVD ROM Lead Free Finish/ RoHS Compliant (Note 1) o TV, DVD, DVR, set top box o Cell Phones, Personal Navigation / GPS o MP3 players ,Cameras, Video Recorders Notes: 1.
