HDSP-0773

Notes:
1. The nominal thermal resistance of a display mounted in a socket that is soldered onto a printed circuit board is R_JA = 50/W/device. The device package thermal resistance is R_J-PIN = 15 /W/device. The thermal resistance device pin-to-ambient through the PC board should not exceed 35/W/device for operation at TA = +85.
2. Voltage values are with respect to device ground, pin 6.
3. These displays are categorized for luminous intensity with the intensity category designated by a letter code located on the back of the display package. Case temperature of the device immediately prior to the light measurement is equal to 25.

These HDSP-0773 solid state display devices are designed and tested for use in adverse industrial environments. The character height is 7.4 mm (0.29 inch). The numeric and hexadecimal devices incorporate an on-board IC that contains the data memory, decoder and display driver functions.

The numeric HDSP-0773 decode positive BCD logic into characters"0-9", a "" sign, decimal point, and a test pattern. The hexadecimal  devices decode positive BCD logic into 16 characters, "0-9, A-F."An input is provided on the hexadecimal devices to blank the display (all LEDs off) without losing the contents of the memory.

The over range HDSP-0773 displays "±1" and right hand decimal point and is typically driven via external switching transistors.
