DC CHARACTERISTICS (CONTINUED)

Standard Operating Conditions (unless otherwise specified):

Operating Temperature: -40°C

 TA  +125°C (Extended)

All parameters apply across the specified operating ranges unless noted.

VDD = +2.7V to 5.5V, VREF = +1.000V to VDD, VSS =0V,

RL =2 k from VOUT to GND, CL = 100 pF.

Typical specifications represent values for VDD =5.5V, TA =+25°C.

The LAT/HVC pin will be at one of

the three input levels (VIL, VIH or

VIHH)(1,11)

The LAT/HVC pin must supply the

required MTP programming

current (up to 6.4 mA).

(Note 1)

Note 1

This parameter is ensured by design.

Note 11

High voltage on the LAT/HVC pin must be limited to the command + programming time. After the

programming cycle, the LAT/HVC pin voltage must be returned to 5.5V or lower.

Note 12

After 32 MTP write cycles, writes are inhibited and the 32nd write value is retained (not corrupted).
