74LVC241A
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 IOFF. The IOFF 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 VCC = 3V
• CMOS Low Power Consumption
• IOFF 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
Applications
• Schmitt Trigger Action at All Inputs
• Typical VOLP (Quiet Output Ground Bounce) Less than 0.8V with
VCC = 3.3V and TA = +25°C
• Typical VOHV (Quiet Output Dynamic VOH) Greater than 2.0V
with VCC = 3.3V and TA = +25°C
• ESD Protection Tested per JESD 22
Exceeds 200-V Machine Model (A115)
Exceeds 2000-V Human Body Model (A114)
