Technical Examples

A level shifting circuit with a power monitor enable for mixed-voltage applications is described. The level shifter translates signals from a first power supply voltage domain to a second. The level shifter provides a known output state, rather than an undefined mid-rail state, when either of the power supplies for the voltage domains is not adequately powered. In addition, the level shifter is IDDQ (quiescent current) compliant when static, drawing negligible current from the power supply. The level shifter can be used with a power monitor circuit, which controls the level shifter during power-up with an enable signal.
