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
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.
