NXB0108

Dual supply translating transceiver; auto direction sensing; 3-state

The NXB0108 is an 8-bit, dual supply translating transceiver with auto direction sensing, that enables bidirectional voltage level translation. It features two 8-bit 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 1.2 V and 3.6 V and VCC(B) can be supplied at any voltage between 1.65 V and 5.5 V, making the device suitable for translating between any of the low voltage nodes (1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V and 5.0 V).

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.

Features and benefits

  • Wide supply voltage range:

    • VCC(A): 1.2 V to 3.6 V and VCC(B): 1.65 V to 5.5 V

  • IOFF circuitry provides partial Power-down mode operation

  • Inputs accept voltages up to 5.5 V

  • ESD protection:

    • HBM: ANSI/ESDA/Jedec JS-001 Class 2 exceeds 2500 V for A port

    • HBM: ANSI/ESDA/Jedec JS-001 Class 3B exceeds 15000 V for B port

    • CDM: ANSI/ESDA/Jedec JS-002 Class C3 exceeds 1500 V

  • Latch-up performance exceeds 100 mA per JESD 78B Class II

  • Multiple package options

  • Specified from −40 °C to +85 °C and −40 °C to +125 °C
