NXB0102DCH

NXB0102DCH is a 2bit, dual supply translating transceiver with auto direction sensing, that enables bidirectional voltage level translation. It features two 2bit input-output ports (An and Bn), one output enable input (OE) and two supply pins (VCC(A) and VCC(B)). VCC(A) can be supplied at any voltage between 1.2V and 3.6V and VCC(B) can be supplied at any voltage between 1.65V and 5.5V, making the device suitable for translating between any of the low voltage nodes (1.2V, 1.5V, 1.8V, 2.5V, 3.3V and 5V). Pins An and OE are referenced to VCC(A) and pins Bn are referenced to VCC(B). A LOW level at pin OE causes the outputs to assume a high-impedance OFF-state. This device is fully specified for partial power-down applications using IOFF. The IOFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down.

• IOFF circuitry provides partial Power-down mode operation
• Inputs accept voltages upto 5.5V, ESD protection
• Latch-up performance exceeds 100mA per JESD 78B Class II
• Input leakage current is ±1μA max at (OE input;VI= 0V to 3.6V;VCC(A) = 1.2V to 3.6V)
• Input capacitance is 2pF typ at (OE input;VCC(A) = 1.2V to 3.6V;VCC(B) = 1.65V to 5.5V)
• Propagation delay is 7.5ns at (1.8V, A to B, VCC(A) = 1.2V; Tamb = 25°C)
• Supply current is 3μA max at (VCC(A) = 1.4V to 3.6V;VCC(B) = 1.65V to 5.5V)
• Operating temperature range from -40°C to +125°C
• VSSOP8 package
