U74AC240 Datasheet | Unisonic Technologies

DESCRIPTION CMOS IC The U74AC240 is a octal buffers/drivers with 3-state outputs. It is organized as two 4-bit buffers/drivers with separate output-enable ( OE ) inputs. When OE is high, the Y outputs are in a high-impedance state, and the outputs neither load nor drive the bus lines. When OE is low, the device passes inverted data from the A inputs to the Y outputs. The U74AC240 is designed to improve the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. - FEATURES - Wide Supply Voltage Range from 2V to 6V - Max t PD of 6.5 ns from A to Y at 5V - Low Power Consumption, ICC = 4μA (Max.) at 5.5V - ±24m A Output Driver at 5.5V .Data Sheet.net/ - ORDERING INFORMATION Ordering Number Lead Free Halogen Free U74AC240L-P20-R U74AC240G-P20-R U74AC240L-P20-T U74AC240G-P20-T Package TSSOP-20 TSSOP-20 Packing Tape Reel Tube .unisonic..tw Copyright © 2011 Unisonic Technologies Co., Ltd 1 of 6 QW-R502-675.A Datasheet pdf - http://..co.kr/ - PIN CONFIGURATION 1OE 1A1 2Y4 1A2 2Y3 1A3 2Y2 1A4 2Y1 GND 1 2 3 4 5 6 7 8 9 10 20 V CC 19 2OE 18 1Y1 17 2A4 16 1Y2 15 14 13 12 11 2A3 1Y3 2A2 1Y4 2A1 CMOS IC - FUNCTION TABLE INPUTS OUTPUT A H L X Y L H Z - LOGIC DIAGRAM 1OE 1 2OE .Data Sheet.net/ 1A1 1Y1 2A1 2Y1 1A2 1Y2...
