The 7389C is a 41⁄2-inch image orthicon
The orthicon tube (specifically the image orthicon, or IO) was a highly sensitive type of vacuum tube used as the primary image sensor in early black-and-white and color television cameras from the 1940s to the 1970s. It was significantly more sensitive than its predecessor, the iconoscope, and could produce clear images even in low-light conditions, such as by candlelight.
The orthicon itself doesn’t directly produce a digital signal—it outputs an analogue signal. To make it digital, you’d need an additional step: an analogue-to-digital converter (ADC).
