1 / 6 page  UNISONIC TECHNOLOGIES CO., LTD U74HC240 CMOS IC www.unisonic.com.tw 1 of 6 Copyright © 2017 Unisonic Technologies Co., Ltd QW-R502-498.D OCTAL BUFFERS AND LINE DRIVERS WITH 3-STATE OUTPUTS DESCRIPTION The U74HC240 is a octal buffer and line driver 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 U74HC240 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; and 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 tpd of 9 ns from A to Y at 6V * Low power consumption, ICC = 8 μA (Max.) at 6V * ±6 mA output driver at 5V * Low Input Current of 1 μA Max SOP-20 SSOP-20 TSSOP-20 ORDERING INFORMATION Ordering Number Lead Free Halogen Free Package Packing U74HC240L-S20-R U74HC240G-S20-R SOP-20 Tape Reel U74HC240L-R20-R U74HC240G-R20-R SSOP-20 Tape Reel U74HC240L-P20-R U74HC240G-P20-R TSSOP-20 Tape Reel ■ MARKING |
