INFORMATION
DESCRIPTION:
FEATURES:
This 16-bit bus transceiver is built using advanced CMOS technology. The
AUC16245 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 AUC16245 is designed with a ±9mA output driver. This driver is capable
of driving a moderate load while maintaining speed performance.
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: ±9mA @ VDD = 2.3V
• Supports hot insertion
• Available in TSSOP, TVSOP, and VFBGA packages
APPLICATIONS:
• High performance, low voltage communications systems
• High performance, low voltage computing systems
