U74HC240

UNISONIC TECHNOLOGIES CO., LTD U74HC240 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  ORDERING INFORMATION Ordering Number Lead Free Halogen Free U74HC240L-S20-R U74HC240G-S20-R U74HC240L-R20-R U74HC240G-R20-R U74HC240L-P20-R U74HC240G-P20-R Package SOP-20 SSOP-20 TSSOP-20 CMOS IC SOP-20 SSOP-20 TSSOP-20 Packing Tape Reel Tape Reel Tape Reel ■ MARKING www.unisonic.com.tw Copyright © 2023 Unisonic Technologies Co., Ltd 1 of 6 QW-R502-498.E U74HC240  PIN CONFIGURATION 1OE 1 1A1 2 2Y4 3 1A2 4 2Y3 5 1A3 6 2Y2 7 1A4 8 2Y1 9 G...
