It is designed for very high−speed, very low−power operation in 1.8 V, 2.5 V or 3.3 V systems. The 74VCXH245 is designed as a byte control. The Transmit/Receive (T/Rn) inputs determine the direction of data flow through the bidirectional transceiver. Transmit (active−HIGH) enables data from A ports to B ports; Receive (active−LOW) enables data from B to A ports. The Output Enable input (OE), when HIGH, disables both A and B ports by placing them in a HIGH Z condition. The data inputs include active bushold circuitry, eliminating the need for external pullup resistors to hold unused or floating inputs at a valid logic state. Features • Designed for Low Voltage Operation: V CC = 1.65−3.6 V • High Speed Operation: 3.5 ns max for 3.0 to 3.6 V 4.2 ns max for 2.3 to 2.7 V 8.4 ns max for 1.65 to 1.95 V • Static Drive: ±24 mA Drive at 3.0 V ±18 mA Drive at 2.3 V ±6 mA Drive at 1.65 V • Includes Active Bushold to Hold Unused or Floating Data Inputs at a Valid Logic State • Near Zero Static Supply Current in All Three Logic States (20 mA) Substantially Reduces System Power Requirements • Latchup Performance Exceeds ±200 mA @ 85°C • ESD Performance: Human Body Model >2000 V Machine Model >200 V • Pb−Free Package is Available *For additional information on our Pb−Free strategy and soldering details, please download the ON Semiconductor Soldering and Mounting Techniques Reference Manual, SOLDERRM/D. http://onsemi.com MARKING DIAGRAM QFN MNR2 SUFFIX CASE 485AA A = Assembly Location L = Wafer Lot Y = Year W = Work Week G = Pb−Free Package (Note: Microdot may be in either location) Device Package Shipping† ORDERING INFORMATION 74VCXH245MNR2 QFN 3000/Tape&Reel 74VCXH245MNR2G QFN (Pb−Free) 3000/Tape&Reel 1 VCX H245 ALYW G G †For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specifications Brochure, BRD8011/D.
