Absolete 7-seg display

Help! I am looking for a datasheet on the LT303 (Lite-On?) 7-seg display at all the usual places, to no avail. This thing has some sort of address decoder on-board.
Thanks and kudos to anyone who keeps old databooks! E

Hi canadaelk,

I did find this. Its a start.

LT303
Seven-Segment Numeric LED Display
Lite-On Technology Corporation
LEDs,Displays
Package Style (Basic)=DIP
Number of Characters=1
Color=Red
Character Height (mm)=8
Peak Wavelength (m)=655n
Iv Min.(cd) Luminous Intensity=500u
@I(F) (A) (Test Condition)=20m
V(F) Max.(V) Forward Voltage=2.0
@I(F) (A) (Test Condition)=20m
I(F) Max. (A) Forward Current=25m
Status=Discontinued
Package=DIP

Will continue to hunt.

Thanks I! I am interested in building the this frequency counter: https://alternatezone.com/electronics/freq.htm and need to understand the functions of inputs 1, 6 & 7 of the LT303s to re-work it with current parts. E

From the schematic, pin #1 is probably for leading zero suppression, pin #6 is digit selection, pin #7 is unused (presumably decimal point). The display is a common cathode type.
