CMOS 16-BIT LEVEL SHIFTING TRANSCEIVER WITH 3-STATE OUTPUTS
IDT74AUC164245
VDDA VDDB 0.8V 2.7V Inputs/outputs tolerant 3.6V 2000V MIL-STD-883, Method 3015; 200V using machine model 200pF, Supports insertion: port output drivers: ±9mA 2.3V Available TSSOP, TVSOP, VFBGA packages
APPLICATIONS:
High performance, voltage communications systems High performance, voltage computing systems
This 16-bit level shifting transceiver built using advanced CMOS technology. AUC164245 ideal asynchronous communications between data buses. control function implementation minimizes external timing requirements. AUC164245 16-bit level shifting transceiver contains separate supply rails. port designed track VDDB, which accepts voltages from 0.8V 2.7V. port control inputs designed track VDDA, which accepts voltages from 0.8V 2.7V. This allows user-selectable translation various level shifting system environments. This device used 16-bit transceiver 8-bit transceivers. allows data transmission from from bus, depending logic level direction-control (DIR) input. output-enable (OE) input used disable device that buses effectively isolated. This device fully specified partial power-down applications using IOFF. IOFF circuitry disables outputs, preventing damaging current backflow through device when powered down. AUC164245 ports designed with ±9mA output drivers. These drivers capable driving moderate loads while maintaining high speed performance. ensure high-impedance state during power power down, should tied VDDA through pull-up resistor; minimum value resistor determined current-sinking capability driver.
