Notes:
1. Nominal thermal resistance of a display mounted in a socket which is soldered into a printed circuit board:
Θ
JA = 50°C/W; ΘJC = 15°C/W.
2.
Θ
CA of a mounted display should not exceed 35°C/W for operation up to TA = +100°C.
3. Voltage values are with respect to device ground, pin 6.
4. All typical values at VCC = 5.0 Volts, TA = 25°C.
5. These displays are categorized for luminous intensity with the intensity category designated by a letter located on the back of the
display contiguous with the Hewlett-Packard logo marking.
6. The luminous intensity at a specific ambient temperature, Iv(TA), may be calculated from this relationship:
Iv(TA)=Iv(25°C)(0.985)
(T -25
°C).
7. Applies only to 4N54.
8. The dominant wavelength,
λ
d, is derived from the CIE chromaticity diagram and represents the single wavelength which defines the
color of the device.
