SNLS273A – JULY 2010 – REVISED MARCH 2013

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for

which the device is intended to be functional, but specific performance is not ensured. For ensured specifications and test conditions,

see the DC ELECTRICAL CHARACTERISTICS and AC ELECTRICAL CHARACTERISTICS tables.

(1)

Supply current is measured with inputs connected to VCC and outputs driven low but not connected to a load.

(2)

Command execution cycle = 0.5 µs.

(3)

In standby mode, the internal clock is switched off. Supply current in standby mode is measured with inputs connected to VCC and

outputs driven low but not connected to a load.

(4)

Applied to all digital pins (including RESET) except for SLOWCLK when configured for an external clock.

(5)

Specified by design, not tested.

(6)

The sum of all I/O sink/source current must not exceed the maximum total current into VCC and out of GND as specified in the absolute

maximum ratings.
