PO74G16244A 16-Bit Buffer/Line Driver with 3-State Outputs 02/27/08 74 Series GHz Logic FEATURES: DESCRIPTION: . Patented technology . Operating frequency up to 1.125GHz with 2pf load . Operating frequency up to 700MHz with 5pf load . Operating frequency up to 300MHz with 15pf load Potato Semiconductor’s PO74G16244A is designed for world top performance using submicron CMOS technology to achieve 1.125GHz TTL /CMOS output frequency with less than 1.5ns propagation delay. This Octal bus buffer gate is designed for 1.65-V to 3.6-V VCC operation. . Operating frequency up to 100MHz with 50pf load . VCC Operates from 1.65V to 3.6V . Propagation delay < 1.5ns max with 15pf load . Low input capacitance: 4pf typical . Available in 48pin TSSOP package The PO74G16244A features independent line driver swith 3-state outputs. Each output is disabled when the associated output- enable(OE) input is high. Pin Configuration Logic Block Diagram Inputs can be driven from either 3.3V or 5V devices. This feature allows the use of these devices as translators in a mixed 3.3V/5V system environment. 1OE 1OE 1Y1 1Y2 GND 1Y3 1Y4 VCC 2Y1 2Y2 GND 2Y3 2Y4 3Y1 3Y2 GND 3Y3 3Y4 VCC 4Y1 4Y2 GND 4Y3 4Y4 4OE 1 48 2 47 3 46 4 45 5 44 6 43 7 42 8 41 9 40 10 39 11 38 12 37 13 36 14 35 15 34 16 33 17 32 18 31 19 30 20 29 21 28 22 27 23 26 24 25 2OE 1A1 1A2 GND 1A3 1A4 VCC 2A1 2A2 GND 2A3 2A4 3A1 3A2 GND 3A3 3A4 VCC 4A1 4A2 GND 4A3 4A4 3OE 1A1 1A2 1A3 1A4 2OE 2A1 2A2 2A3 2A4 1 3OE 47 2 46 3 44 5 43 6 1Y1 3A1 1Y2 3A2 1Y3 3A3 1Y4 3A4 48 4OE 41 8 40 9 38 11 37 12 2Y1 4A1 2Y2 4A2 2Y3 4A3 2Y4 4A4 25 36 13 35 14 33 16 32 17 3Y1 3Y2 3Y3 3Y4 24 30 19 29 20 27 22 26 23 4Y1 4Y2 4Y3 4Y4 Pin Description INPUTS OE A OUTPUT Y L H H L L L H X Z 1 Copyright © Potato Semiconductor Corporation PO74G16244A 16-Bit Buffer/Line Driver with 3-State Outputs 02/27/08 74 Series GHz Logic Maximum Ratings Description Max Unit Storage Temperature -65 to 150 °C Operation Temperature -40 to 85 °C Operation Voltage -0.5 to +4.6 V Input Voltage -0.5 to +5.5 V Output Voltage -0.5 to Vcc+0.5 V Note: stresses greater than listed under Maximum Ratings may cause permanent damage to the device.
