摘要
A bi-directional buffer includes at least a first and second pair of one-shots and transistors. At least the first pair of one-shots and the first pair of transistors enable a second input/output (I/O) terminal to follow a first I/O terminal. At least the second pair of one-shots and the second pair of transistors enable the first I/O terminal to follow the second I/O terminal. There is a detection of whether the direction of a signal is from the first I/O terminal to second I/O terminal, or vise versa. If the direction is from the first I/O terminal to the second I/O terminal, there is an at least temporarily disabling the second pair of one-shots to thereby reduce feedback that may occur from the second I/O terminal to the first I/O terminal. If the direction is from the second I/O terminal to the first I/O terminal, there is an at least temporarily disabling the first pair of one-shots to thereby reduce feedback that may occur from the first I/O terminal to the second I/O terminal.
