Receiver outputs can interface directly to 3V logic circuits. Included on the chip is a shutdown pin for reducing supply current to near zero. All receivers and drivers assume high impedance states during shutdown. When driver disable is high the charge pump and drivers turn off. Receivers continue to operate during driver disable. The LT1342 is fully compliant with all EI...
