16-Bit Dual-Supply Translating Transceiver with Configurable Voltage Translation and 3-State Outputs
GENERAL DESCRIPTION

The 74AVC16T245 is a 16-bit dual-supply translating transceiver with configurable voltage translation and 3-state outputs. The device can be used as two 8-bit transceivers or one 16-bit transceiver. The nAn and nBn are two 8-bit input-output data ports. nDIR are the direction control inputs and nOE are the output enable inputs. VCCA and VCCB are the supply pins. The supply voltage of VCCA and VCCB can range from 0.8V to 3.6V, making the device suitable for bidirectional translating among any of the 0.8V, 1.2V, 1.5V, 1.8V, 2.5V and 3.3V voltage nodes. The nAn, nDIR and nOE signals are referenced to VCCA and nBn signals are referenced to VCCB.

When nDIR is set high, it allows transmission from nAn to nBn. When nDIR is set low, it allows transmission from nBn to nAn. nOE can be used to make the outputs disabled so that the buses are effectively isolated. In suspend mode, both nAn and nBn are in the high-impedance state when either VCCA or VCCB input is at GND level.

This device is highly suitable for partial power-down applications using power-off leakage current (IOFF) circuit. When the device is powered down, the current backflow will be prevented from passing through the device.
