Benefits of Lower Operating Voltage
The MACHLV210 has an operating voltage range of
3.0 V to 3.6 V. Low voltage allows for lower operating
power consumption, longer battery life, and/or smaller
batteries for portable applications.
Because power is proportional to the square of the volt-
age, reduction of the supply voltge from 5.0 V to 3.3 V
significantly reduces power consumption. This directly
translates to longer battery life for portable applications.
Lower power consumption can also be used to reduce
the size and weight of the battery. Thus, 3.3-V designs
facilitate a reduction in the form factor.
The MACHLV210 is not designed to interface between
3.3-V and 5.0-V logic. Latch-up may occur if VOH for the
MACHLV210 is greater than VIH for the 5.0-V device.
Although this scenario is unlikely, interfacing the
MACHLV210 with 5.0-V devices is not encouraged
without necessary latch-up design precautions.
