74LVC241A

NEW PRODUCT

OCTAL BUFFER/LINE DRIVER WITH 3 STATE OUTPUTS

Description

The 74LVC241A provides two 4-bit buffers/drivers with separate

output-enable (1OE and 2OE) inputs. When 1OE is low or 2OE is

high, the device passes noninverted data from the A inputs to the

Y outputs. When 1OE is high or 2OE is low, the outputs for the

respective buffers/drivers are in the high-impedance state.

The device is designed for operation with a power supply range of

1.65V to 3.6V.

The inputs are tolerant to 5.5V allowing this device to be used in a

mixed voltage environment. The device is fully specified for partial

power down applications using I

OFF

. The I

OFF

circuitry disables the

output preventing damaging current backflow when the device is

powered down.

Features

• Supply Voltage Range from 1.65V to 3.6V

• Sinks or Sources 24mA at V

CC

= 3V

• CMOS Low Power Consumption

• I

OFF

Supports Partial -Power Down Operation

• Inputs or Outputs Accept up to 5.5V

• Inputs Can Be Driven by 3.3V or 5V Allowing for Mixed Voltage

Notes: 6. Stresses beyond the absolute maximum may result in immediate failure or reduced reliability. These are stress values and device operation should be

within recommend values.

7. Forcing the maximum allowed voltage could cause a condition exceeding the maximum current or conversely forcing the maximum current could

cause a condition exceeding the maximum voltage. The ratings of both current and voltage must be maintained within the controlled range.
