This device is ESD sensitive: Meets Class 1ESD

test requirements (Human body Model, HBM), in

accordance with MIL-STD-883C, Method 3015. Do

not operate or store near strong electrostatic

fields.

Use

appropriate

ESD

precautions.

Electrical Characteristics

Unless otherwise stated, these specifications apply for Ta = -40

°C to 85°C, 4.75<VDD<5.5V. All voltages are with respect to

Ground; Positive currents flow into device pins.

CAGC = 4.7µF, CTH = .047µF, VDDRF= VDDBB = VDD.

REFOSC

frequency = 4.90MHz.
