UNISONIC TECHNOLOGIES CO., LTD U74LVC1G18 Preliminary CMOS IC 1-OF-2 NON-INVERTING DEMULTIPLEXER WITH 3-STATE DESELECTED OUTPUT 4 1 DESCRIPTION The U74LVC1G18 is a 1-of-2 non-inverting demultiplexer with 3-state output. When the select input S is low data passes from A (input) to 1Y (output) and 2Y (output) is in the high-impedance state. When the select input S is high data passes from A (input) to 2Y (output) and 1Y (output) is in the high-impedance state. The U74LVC1G18 is designed for 1.65V to 5.5V operation and it can be driven from either 3.3V or 5.5V devices. Therefore, it can be used in a mixed 3.3V and 5V environment. The U74LVC1G18 is fully specified for partial-power-down applications using IOFF. The IOFF circuitry disables the outputs and prevents damaging current backflow through the device when it is powered down. 5 6 2 3 SOT-363 6 5 4 1 2 3 SOT-26 FEATURES * Wide supply voltage range from 1.65V to 5.5V * Max tPD of 3.4 ns at 3.3V * Up to 5.5V inputs accept voltages * Low power consumption, ICC = 10 μA (Max.) * ±24 mA output driver at 3.3V * Typical VOLP (Output Ground Bounce) < 0.8V, VCC = 3.3 V, TA = 25 ℃ * Typical VOHV (Output VOH undershoot) > 2V, VCC = 3.3 V, TA = 25 ℃ * IOFF supports partial-power-down mode operation ORDERING INFORMATION Ordering Number Lead Free Halogen Free U74LVC1G18L-AL6-R U74LVC1G18G-AL6-R U74LVC1G18L-AG6-R U74LVC1G18G-AG6-R U74LVC1G18L-AL6-R (1)Packing Type Package Packing SOT-363 SOT-26 Tape Reel Tape Reel (1) R: Tape Reel (2)Package Type (2) AL6: SOT-363, AG6: SOT-26 (3)Lead Free (3) G: Halogen Free, L: Lead Free www.unisonic.com.tw Copyright © 2011 Unisonic Technologies Co., Ltd 1 of 7 QW-R502-559.a U74LVC1G18 Preliminary CMOS IC MARKING 6 5 4 3A8□ 1 2 G: Halogen Free L: Lead Free 3 PIN CONFIGURATION FUNCTION TABLE INPUTS S L L H H H=High Level OUTPUT A L H L H Y0 L H Z Z Y1 Z Z L H L=Low Level LOGIC DIAGRAM (positive logic) 6 S A 1 3 UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw Y0 4 Y1 2 of 7 QW-R502-559.a U74LVC1G18 Preliminary CMOS IC ABSOLUTE MAXIMUM RATING (unless otherwise specified) PARAMETER SYMBOL RATINGS UNIT Supply Voltage VCC -0.5~6.5 V Input Voltage VIN -0.5~6.5 V Output Voltage (any output in the high-impedance or VOUT -0.5~6.5 V power-off state) Output Voltage (any output in the high or low state) VOUT -0.5~VCC+0.5 V Input Clamp Current IIK -50 mA Output Clamp Current IOK -50 mA Output Current IOUT ±50 mA VCC or GND Current ICC ±100 mA Ptot mW Power Dissipation TA=-40°C to +85°C 250 Storage Temperature TSTG -65 ~ +150 °C Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied. 1.
