Most ROM ICs have tri- state outputs that:
A) allow for three separate data input lines.
B) isolate the registers from the data bus during read operations.
C) allow the bidirectional flow of data between the bus lines and the ROM registers.
D) permit the connection of many ROM chips to a common data bus.

Question

Tri-state outputs on ROM ICs allow for the connection of multiple ROM chips to a common data bus by enabling an output, disabling it to a high-impedance state, or maintaining a normal logic level, thus facilitating the sharing of the bus without interference.
