Pin11 is the DC supply pin. The supply voltage must be free from noise and preferably from a linear

regulator with less than 3mV PKPK noise. Many modern regulators have noise below 100uV RMS

and these are ideal. See the section on choice of power supply.

7. Absolute Maximum Ratings

Maximum voltage applied to Pin 2 (Vcc) 5.5volt

Maximum voltage applied to Pin 2 (Reset) Vcc + 0.7v, -0.7v

Maximum current drawn from Pin 3 ( Antenna) +/- 75mA

Maximum 125 KHz RF Voltage at Pin 4 (Antenna) +/- 80volt Peak

Maximum current drawn from Pin 5 (Card Present) +/- 5mA

Maximum current drawn from Pin 6 (Tag in Range) +/- 5mA

Maximum Voltage at Pin 7 (Format Selector) Vcc + 0.7v, -0.7v

Maximum current drawn from Pin 8 (Data1) +/- 5mA

Maximum current drawn from Pin 9 (Data0) +/- 5mA

Maximum current drawn from Pin 10 (Beeper) +/- 10mA

Additionally, Pins 5, 6, 7, 8, 9 & 10 may not have a voltage exceeding Vcc + 0.7v, -0.7v

These ratings are absolute maximums and operation at or near the maximums may cause stress

and eventual damage or unpredictable behaviour.
