Product Introduction
The SN74AXC4T774 is a 4-bit non-inverting bus transceiver that uses two separate configurable power rails. The device operates when the VCCA and VCCB supply voltages are as low as 0.65V. Port A tracks VCCA and supports any supply voltage in the range of 0.65V to 3.6V. Port B tracks VCCB and likewise supports any supply voltage in the range of 0.65V to 3.6V. In addition, the SN74AXC4T774 is compatible with single-supply systems.
The SN74AXC4T774 device is designed for asynchronous communication between data buses. Depending on the logic level of the direction control inputs (DIRx), the device transfers data from the A bus to the B bus, or from the B bus to the A bus. The output enable input (OE) disables the outputs to effectively isolate the buses. The SN74AXC4T774 device is designed so that the control pins (DIRx and OE) are referenced to VCCA.
To ensure that the level translator I/Os are in a high-impedance state during power-up or power-down, the OE pin should be connected to VCCA through a pull-up resistor.
The device fully complies with the specifications for partial power-down applications using Ioff current. When the device is powered down, the Ioff protection circuit ensures that no excess current is drawn from or supplied to the inputs, outputs, or combined I/Os biased to a specific voltage.
The VCC isolation feature ensures that when VCCA or VCCB falls below 100mV, the I/O port outputs can be disabled to place them in a high-impedance state.
Glitch-free power sequencing allows the power rails to be turned on or off in any order, providing robust power sequencing performance.
