In digital electronics, a tri-state or three-state buffer is a type of digital buffer that has three stable states: a high output state, a low output state, and a high-impedance state. In the high-impedance state, the output of the buffer is disconnected from the output bus, allowing other devices to drive the bus without interference from the tri-state buffer. This can be useful in situations w… WebThe 8255 Programming and Operation sets the INTR when STB signal is ‘one’, IBF signal is ‘one’ and INTE is ‘one’, indicating CPU that the data from the input device is available in the input buffer. This signal is reset by the falling edge of the RD signal i.e. immediately after reading the data from the input buffer.
