Apogee Semiconductor AP54RHC505 Rad-Hard 5-Ch Translators w/Bus Hold

The Apogee Semiconductor AP54RHC505 Rad-Hard 5-Channel Level Translators are part of the AP54RHC logic family operating across a voltage supply range of 1.65V to 5.5V. The AP54RHC505 can operate across this voltage supply range on its supply voltage inputs, V_CCA and V_CCY.

The output enable control pin facilitates outputs placed in a high impedance (high-Z) state, simplifying usage in applications with shared busses or mixed power domains. Furthermore, the outputs are placed in high-Z when V_CCA is absent, ensuring that no loading or leakage paths are experienced at the output nodes when the input rail is not powered.

The AP54RHC505 supports zero-power penalty™ cold-sparing along with Class 2 ESD protection on all inputs and outputs. A proprietary output stage and full power-on reset (POR) circuit allow the AP54RHC505 to be cold-spared in any redundant configuration with no static power loss on any device pad. The redundant output stage also features a high drive capability with low static power loss.

The AP54RHC505 also features a triple-redundant design throughout its entire circuitry, which allows it to be immune to single-event transients (SET) without requiring additional redundant devices. The AP54RHC505 is available in an SMD TSSOP-14 package with an extended operating temperature range of -55°C to +125°C.
