Hallo Gemeinde, ich suche vergeblich nach einem Datenblatt für ein IC SN76489AN. Könnt Ihr mir bitte helfen? Ich habe das hier gefunden, aber auch zu allen anderen genannten erhalte ich no results:

"The SN76489 was originally designed to be used in the TI-99/4 computer, where it was first called the TMS9919 and later SN94624, and had a 500 kHz max clock input rate. Later, when it was sold outside of TI, it was renamed the SN76489, and a divide-by-8 was added to its clock input, increasing the max clock input rate to 4 MHz, to facilitate sharing a crystal for both NTSC colorburst and clocking the sound chip. A version of the chip without the divide-by-8 input was also sold outside of TI as the SN76494, which has a 500 kHz max clock input rate.[1]"

Hier vielleicht:
