VCC = 3 to 5.5V, TA = Operating Temperature Range, unless otherwise noted.

Stresses above those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent device failure. Functionality at

or above these limits is not implied. Exposure to absolute maximum ratings for extended periods may affect device reliability.

Operating ranges define those limits between which the functionality of the device is guaranteed.

Note 1: ICC is measured with PBRST and all outputs open and inputs within 0.5V of supply rails.

Note 2: PBRST has an internal 40k

Ω (typical) pull-up resistor to V

CC.

Note 3: Guaranteed by design at TA = 25°C.

Note 4: PBRST must be held low for a minimum of 20ms to guarantee a reset.
