74LV08A
QUADRUPLE 2-INPUT AND GATES
Description
The 74LV08A provides provides four independent 2-input AND gates
with standard push-pull outputs. The device is designed for operation
with a power supply range of 2.0V to 5.5V.
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
output preventing damaging current backflow when the device is
powered down.
The gates perform the Boolean function:
or B
Y
BAY
OFF
. The I
circuitry disables the
OFF
Features
Wide Supply Voltage Range from 2.0V to 5.5V
Sinks or sources 12mA at V
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 voltage
translation applications.
Schmitt Trigger Action at All Inputs
ESD Protection Tested per JESD 22
Exceeds 200-V Machine Model (A115)
Exceeds 2000-V Human Body Model (A114)
