Abstract
A bidirectional voltage translator (102) includes a first port (200/400), a second port (202/402) and a bidirectional translator circuit (208-215/404-408, 410, 412-415) coupled between the first and second ports (200/400,202/402). The first and second ports (200/400,202/402) communicate signals at a first voltage level and a second voltage level, respectively. The second voltage level is different from the first voltage level. When a first port signal input at the first voltage level at the first port (200/400) is detected, the bidirectional translator circuit (208-215/404-408, 410, 412-415) translates the first port signal into the second voltage level at the second port (202/402) and disables translation of a signal at the second port (202/402) to the first port (200/400). When a second port signal input at the second voltage level at the second port (202/402) is detected, the bidirectional translator circuit (208-215/404-408, 410, 412-415) translates the second port signal into the first voltage level at the first port (200/400) and disables translation of a signal at the first port (200/400) to the second port (202/402).
