NTSX2102 Block Diagram

NTSX2102 Block Diagram

An NTSX2102 device has two 2-bit input-output ports (An and Bn), one output enable input (OE) and two supply pins (VCC(A) and VCC(B)). It is a 2-bit, dual supply translating transceiver with auto direction sensing, that enables bidirectional voltage level translation. Both supplies can be supplied at any voltage between 1.65 V and 5.5 V.

This flexibility makes the device suitable for translating between any of the voltage nodes (1.8 V, 2.5 V, 3.3 V and 5.0 V).

Why Used

  • Inputs accept voltages up to 5.5 V
  • Latch-up performance exceeds 100 mA per JESD 78B Class II
  • Multiple package options
  • Wide supply voltage range:
    • VCC(A): 1.65 V to 5.5 V and VCC(B): 1.65 V to 5.5 V
  • Maximum data rates:
    • 50 Mbps
  • ESD protection:
    • HBM JS-001 Class 2 exceeds 2000 V
    • CDM JESD22-C101E exceeds 2000 V

Where Used

  • UART
  • GPIO
  • I²C/SMBus
