ELECTRICAL CHARACTERISTICS (continued)

(VCC = +4.25V to +5.5V for L/M versions, VCC = +2.55V to +3.6V for the T/S/R versions, VCC = +2.1V to +2.75V for the Z/Y versions.

TA = -40°C to +125°C, unless otherwise specified. Typical values are at TA = +25°C.) (Note 1)

Note 1: Over-temperature limits are guaranteed by design and not production tested. Devices are tested at TA = +25

°C.

Note 2: Guaranteed by design. Not production tested.
