The SN74AXC8T245 device is an 8-bit non-inverting bus transceiver that resolves voltage level mismatch between devices operating at the latest voltage nodes (0.7V, 0.8V, and 0.9V) and devices operating at industry standard voltage nodes (1.8V, 2.5V, and 3.3V) and vice versa.
The device operates by using two independent power-supply rails (VCCA and VCCB) that operate as low as 0.65V. Data pins A1 through A8 are designed to track VCCA, which accepts any supply voltage from 0.65V to 3.6V. Data pins B1 through B8 are designed to track VCCB, which accepts any supply voltage from 0.65V to 3.6V.
The SN74AXC8T245 device is designed for asynchronous communication between data buses. The device transmits data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level of the direction-control inputs (DIR1 and DIR2). The output-enable (OE) input is used to disable the outputs so the buses are effectively isolated.
The SN74AXC8T245 device is designed so the control pins (DIR and OE) are referenced to VCCA.
This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs when the device is powered down. This inhibits current backflow into the device which prevents damage to the device.
The VCC isolation feature is designed so that if either VCC input supply is below 100mV, all level shifter outputs are disabled and placed into a high-impedance state.
To put the level shifter I/Os in the high-impedance state during power up or power down, tie OE to VCCA through a pullup resistor; the current-sinking capability of the driver determines the minimum value of the resistor.
