UNISONIC TECHNOLOGIES CO., LTD U74LVC1G19 CMOS IC 1-OF-2 DECODER/DEMULTIPLEXER DESCRIPTION The U74LVC1G19 is a 1-of-2 decoder / demultiplexer with a common output enable. This device buffers the data on input A and passes it to the outputs 1Y and 2Y when the enable input signal is LOW. This device is fully specified for partial power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing the damaging backflow current through the device when it is powered down. FEATURES * Operate from 1.65V to 5.5V * Inputs accept voltages to 5.5V * Low power dissipation, ICC=10μA (Max) * ±24mA output drive(VCC=3V) ORDERING INFORMATION Ordering Number Lead Free U74LVC1G19L-AL6-R U74LVC1G19L-AL6-R Halogen Free U74LVC1G19G-AL6-R Package Packing SOT-363 Tape Reel (1)Packing Type (1) R: Tape Reel (2)Package Type (2) AL6: SOT-363 (3)Lead Free (3) Halogen Free, L: Lead Free MARKING www.unisonic.com.tw Copyright © 2012 Unisonic Technologies Co., Ltd 1 of 5 QW-R502-356.A U74LVC1G19 PIN CONFIGURATION PIN DESCRIPTION SYMBOL A GND E 2Y Vcc 1Y CMOS IC PIN 1 2 3 4 5 6 DESCRIPTION Data input Ground(0V) Enable input Data output Supply voltage Data output FUNCTION TABLE INPUT OUTPUT A E L L L H H X Note: H: HIGH voltage level; L: LOW voltage level 1Y L H H 2Y H L H LOGIC DIAGRAM (positive logic) 1 A 1Y 6 2Y 4 3 E IEC logic symbol UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 5 VER.A U74LVC1G19 CMOS IC ABSOLUTE MAXIMUM RATING PARAMETER SYMBOL VCC VIN Supply Voltage Input Voltage RATINGS -0.5 ~ +6.5 -0.5 ~ +6.5 -0.5 ~ VCC+0.5 Output in the high or low state VOUT Output in the high-impedance or -0.5 ~ +6.5 power-off state VCC or GND Current ICC ±100 Continuous Output Current (VOUT=0 to VCC) IOUT ±50 Input Clamp Current (VIN<0) IIK -50 Output Clamp Current (VOUT<0) IOK -50 Storage Temperature Range TSTG -65 ~ +150 Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged.
