IDT74AUCR16245 1.8V CMOS 16-BIT BUS TRANSCEIVER WITH 3-STATE OUTPUTS INDUSTRIAL TEMPERATURE RANGE 1.8V CMOS 16-BIT BUS TRANSCEIVER WITH 3-STATE OUTPUTS IDT74AUCR16245 ADVANCE INFORMATION DESCRIPTION: FEATURES: This 16-bit bus transceiver is built using advanced CMOS technology. The AUCR16245 is designed specifically for asynchronous communications between data buses. The control function implementation minimizes external timing requirements. This device can be used as one 16-bit transceiver or two 8-bit transceivers. It allows data transmission from A bus to B bus or from B bus to A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so that the buses are effectively isolated. This device is fully specified for partial power-down applications using IOFF. The IOFF circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down. The AUCR16245 has series resistors in the device output structure which will reduce line noise when used with light loads. This driver has been designed with a ±4.5mA output driver at the designated threshold levels. To ensure the high-impedance state during power up or power down, OE should be tied to VDD through a pull-up resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. • ESD > 2000V per MIL-STD-883, Method 3015; > 200V using machine model (C = 200pF, R = 0) • 1.8V Optimized • 0.8V to 2.7V Operating Range • Inputs/outputs tolerant up to 3.6V • Output drivers: ±4.5mA @ VDD = 2.3V • Low switching noise • Supports hot insertion • Available in TSSOP, TVSOP, and VFBGA packages APPLICATIONS: • High performance, low voltage communications systems • High performance, low voltage computing systems FUNCTIONAL BLOCK DIAGRAM 1DIR 1 2DIR 48 1A1 25 1OE 47 2A1 2 24 36 13 1B1 TO SEVEN OTHER CHANNELS 2OE 2B1 TO SEVEN OTHER CHANNELS The IDT logo is a registered trademark of Integrated Device Technology, Inc.
