Remarks:

Operation above +100°C ambient is possible if the following conditions are met.

The junction should not exceed T

J=125°C and the case temperature (as measured at pin 1 or the back of the display)

should not exceed TC=100°C.

Maximum allowable dissipation is derived from:

CC=5.25 V, VB=2.4 V, VCOL=3.5 V 20 LEDs on per character, 20% DF.

Dimensions are specified as follows: inch (mm)

B Pulse Width Frequency—50 kHz (max.)

All typical values specified at V

CC=5.0 V and TA=25°C unless otherwise noted.

The displays are categorized for luminous intensity with the intensity category designated by a letter code on the

bottom of the package.

The luminous sterance of the LED may be calculated using the following relationships:

V (cd/m

2) = l

V (Candela)/A (Meter)

V (Footlamberts) = p lv (Candela)/A (Foot)

A=5.3 x 10

–8 m2 = 5.8 x10–7 (Foot)2

Dominant wavelength (l

dom) is derived from the CIE chromaticity diagram and represents the single wavelength

which defines the color of the device.

All typical values specified at V

CC=5.0 V and TA=25°C unless otherwise noted.

10) The luminous intensity is measured at T

A=TJ=25°C. No time is allowed for the device to warm up prior to

measurement.

11) A critical component is a component used in a life-support device or system whose failure can reasonably be

expected to cause the failure of that life-support device or system, or to affect its safety or the effectiveness of that

device or system.

12) Life support devices or systems are intended

(a) to be implanted in the human body,

(b) to support and/or maintain and sustain human life.

If they fail, it is reasonable to assume that the health or the life of the user may be endangered.
