NanoFree™ Package The SN74LVC2G157 device features a common • Supports 5-V VCC Operation strobe (G) input. When the strobe is high, Y is low • Inputs Accept Voltages to 5.5 V and Y is high. When the strobe is low, a single bit is • Max tpd of 6 ns at 3.3 V selected from one of two sources and is routed to the • Low Power Consumption, 10-µA Maximum ICC outputs. The device provides true and complementary data. • ±24-mA Output Drive at 3.3 V NanoFree™ package technology is a major • Typical VOLP (Output Ground Bounce) breakthrough in IC packaging concepts, using the die <0.8 V at VCC = 3.3 V, TA = 25°C as the package. • Typical VOHV (Output VOH Undershoot) >2 V at VCC = 3.3 V, TA = 25°C This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the • Ioff Supports Live Insertion, Partial-Power-Down outputs, preventing damaging current backflow Mode, and Back-Drive Protection through the device when it is powered down. • Can Be Used as a Down Translator to Translate Inputs From a Maximum of 5.5 V Down Device Information(1) to the VCC Level PART NUMBER PACKAGE BODY SIZE (NOM) • Latch-Up Performance Exceeds 100 mA Per SN74LVC2G157DCT SSOP (8) 2.95 mm × 2.80 mm JESD 78, Class II SN74LVC2G157DCU VSSOP (8) 2.30 mm × 2.00 mm • ESD Protection Exceeds JESD 22 SN74LVC2G157YZP DSBGA (8) 1.91 mm × 0.91 mm – 2000-V Human Body Model (A114-A) (1) For all available packages, see the orderable addendum at the end of the data sheet. – 1000-V Charged-Device Model (C101) Logic Diagram (Positive Logic) 2 Applications • Barcode Scanner • Cable Solutions • E-Books • Embedded PC • Field Transmitter: Temperature or Pressure Sensors • Fingerprint Biometrics • HVAC: Heating, Ventilating, and Air Conditioning • Network-Attached Storage (NAS) • Server Motherboard and PSU • Software Defined Radio (SDR) • TV: High Definition (HDTV), LCD, and Digital • Video Communications Systems • Wireless Data Access Cards, Headsets, Keyboards, Mice, and LAN Cards 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
