P4022 EM Microelectronic, P4022 Datasheet - Page 3

• Manufacturer Part Number: P4022
• Description: Multi Frequency Contactless Identification Device
• Manufacturer: EM Microelectronic

Handling Procedures
This device has built-in protection against high
static voltages or electric fields; however, due to
the unique properties of this device, anti-static
precautions should be taken as for any other
CMOS component.
proper operation can only occur when all the
terminal voltages are kept within the supply
voltage range.
