TXU0204 is a four-channel unidirectional level shifter
The TXU0204 is a 4-bit, AD7890BR-4 dual-supply, non-inverting, fixed-direction voltage level translation device. The Ax pin is referenced to the V CCA logic level, the OE pin can be referenced to the V CCA or V CCB logic level, and the Bx pin is referenced to the V CCB logic level. Port A can accept an input voltage of 1.1V~5.5V, and port B can also accept an input voltage of 1.1V~5.5V. When OE is in fixed direction, data transfers can be from A to B or B to A with reference to either supply set high. When OE is set low, all output pins are in a high-impedance state. For a summary of the operation of the control logic, see Device Functional Mode.
characteristic:
Fully configurable dual rail design allows each port to operate from 1.1 V to 5.5 V
●Up to 200 Mbps supports 3.3 V to 5.0 V
● Schmitt trigger input allows slow and noisy input
Inputs with integrated static pull-down resistors prevent channels from floating
High drive strength (up to 12 mA at 5 V)
●Low power consumption
—2.5μA max (25°C)
—6 μA max (–40°C to 125°C)
●V CC isolation and V CC disconnection (I off-float) function
—If V CC input <100 mV or disconnected, all outputs are disabled and become high impedance
●I off supports partial power-down mode operation
Control logic (OE) with V CC(MIN) circuit allows control from A or B port
●Pinout compatible with TXB series level shifters
● Additional variants available to support common applications: TXU0204 , TXU0304
●Operating temperature from –40°C to +125°C
Latch-up performance exceeds 100 mA per JESD 78, Class II
ESD protection exceeds JESD 22
