U74LVC240

UNISONIC TECHNOLOGIES CO., LTD U74LVC240 OCTAL BUFFER/DRIVER WITH 3-STATE OUTPUTS  DESCRIPTION The U74LVC240 contains two 4-bit line drivers with separate output-enable( OE ) inputs. When OE is low, the device passes data from the A to the Y. When OE is high, the outputs are in the high-impedance state. The U74LVC240 can be used in a mixed 3.3V/5V system environment. This device has power-down protective circuit, preventing device destruction when it is powered down.  FEATURES * Operate From 1.65V to 3.6V * Input Accept Voltages to 5.5V * Partial-Power-Down Mode Operation * Max tpd is 5.9ns at 3.3V  ORDERING INFORMATION Ordering Number U74LVC240G-S20-T U74LVC240G-S20-R U74LVC240G-P20-T U74LVC240G-P20-R Package SOP-20 SOP-20 TSSOP-20 TSSOP-20 CMOS IC Packing Tube Tape Reel Tube Tape Reel  MARKING www.unisonic.com.tw Copyright © 2014 Unisonic Technologies Co., Ltd 1 of 7 QW-R126-009.A U74LVC240  PIN CONFIGURATION CMOS IC  FUNCTION TABLE INPUT OE H L L A × H L OUTPUT Y Z L H UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 7 QW-R126-009.A U74LVC240  LOGIC DIAGRAM (positive logic) CMOS IC  LOGIC SYMBOL UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 3 of 7 QW-R126-009.A U74LVC240 CMOS IC  ABSOLUTE MAXIMUM RATING (TA =25°C, unless otherwise specified) PARAMETER SYMBOL RATINGS UNIT Supply Voltage Input Voltage VCC -0.5~6.5 V VIN -0.5~ 6.5 V Voltage applied to output in high-impedance or power-off state Voltage applied to output i...
