PI4ULS3V08M

1.2V to 3.6V, Universal Bi-directional Level Shifter with

Automatic Direction Control & Advanced Package Solution

Supply voltage range:

VCCA.................... –0.5V to 4.6V

VCCB.................... –0.5V to 4.6V

Input voltage range, VI(1) Control Inputs...... –0.5V to 4.6V

Voltage Range applied to any I/O pins in the high-impedance

or Power-Off state, VIO (1) :

A Port .......................–0.5V to 4.6V

B Port................... –0.5V to 4.6V

Voltage Range applied to any I/O pins in the High or Low

state VIO (1, 2):

A Port.........–0.5V to VCCA +0.5V

B Port.......–0.5V to VCCB +0.5V

Note:

The input negative voltage and output voltage ratings may be exceeded if the input and output current ratings are observed.

This value is limited to 3.6V maximum.

Stresses greater than those listed under MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and

functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not

implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.

Maximum Ratings(3)

(Absolute maximum ratings over operating free-air temperature range, unless otherwise noted)

Input clamp current, IIK (VI <0)................................... –50mA

Output clamp current, IOK (VO <0).............................. –50mA

Continuous output current, IO ....................................... ±20mA

Continuous current through VCCA, VCCB or GND ..... ±100mA

Storage temperature range, TSTG .................... –65°C to 150°C
