Description
The PI4ULS3V502 is a 2-bit configurable dual-
supply autosensing bidirectional level translator that
does not require a direction control pin. The B and A
ports are designed to track two different power supply
rails, VCCB and VCCA respectively.
The PI4ULS3V502 offers the feature that the values
of the VCCB and VCCA supplies are independent.
Design flexibility is maximized because VCCA can be
set to a value either greater than or less than the VCCB
supply.
The PI4ULS3V502 has high output current
capability, which allows the translator to drive high
capacitive loads such as most high frequency EMI filters.
Another feature of the PI4ULS3V502 is that each An
and Bn channel can function as either an input or an
output.
An Output Enable (EN) input is available to reduce
the power consumption. The EN pin can be used to
disable both I/O ports by putting them in 3-state which
significantly reduces the supply current.
PI4ULS3V502 is 2 kV System-Level ESD Capable.

Note:
1. Normal test conditions are V
I
= 0 V, C
IOB
≤ 15 pF and C
IOA
≤ 15 pF, unless otherwise specified.
2.V
CCB
is the supply voltage associated with the I/O B port, and B ranges from +1.35V to 3.6V under normal operating conditions.
3.V
CCA
is the supply voltage associated with the I/O A port, and A ranges from +0.85V to 2.7V under normal operating conditions.
4. Typical values are for V
CCB
= +2.8V, V
CCA
= +1.8V and T
A
= +25°C. All units are production tested at T
A
= +25°C. Limits over
the operating
temperature range are guaranteed by design.
