1.8V CMOS 16-BIT TRANSCEIVER WITH 3-STATE OUTPUTS
IDT74AUC16245 ADVANCE INFORMATION
2000V MIL-STD-883, Method 3015; 200V using machine model 200pF, 1.8V Optimized 0.8V 2.7V Operating Range Inputs/outputs tolerant 3.6V Output drivers: ±9mA 2.3V Supports insertion Available TSSOP, TVSOP, VFBGA packages
APPLICATIONS:
High performance, voltage communications systems High performance, voltage computing systems
This 16-bit transceiver built using advanced CMOS technology. AUC16245 designed specifically asynchronous communications between data buses. control function implementation minimizes external timing requirements. 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. AUC16245 designed with ±9mA output driver. This driver capable driving moderate load while maintaining speed performance. ensure high-impedance state during power power down, should tied through pull-up resistor; minimum value resistor determined current-sinking capability driver.
