General description

The NTS0302 is a 2-bit, dual supply translating transceiver family with auto direction

sensing, that enables bidirectional voltage level translation. It features two 1-bit

input-output ports (A and B), one output enable input (OE) and two supply pins (VCC(A)

and VCC(B)). VCC(A) can be supplied at any voltage between 0.95 V and 3.6 V. VCC(B) 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 (0.95 V, 1.2 V, 1.8 V, 2.5 V, 3.3 V

and 5.0 V). Pins A and OE are referenced to VCC(A) and pin B is referenced to VCC(B). A

LOW level at pin OE causes the outputs to assume a high-impedance OFF-state.

Features and benefits

? Wide supply voltage range:

? VCC(A): 0.95 V to 3.6 V and VCC(B): 1.65 V to 5.5 V

? No power-sequencing required

? Maximum data rate

? Open-drain: 2 Mbps

? Push-pull: 20 Mbps

? Longer one-shot pulse for driving larger capacitive loads with much reduced ringing

and overshoot

? A-side inputs accept voltages up to 3.6 V

? B-side inputs accept voltages up to 5.5 V

? ESD protection:

? HBM JESD22-A114E Class 2 exceeds 2000 V for both ports

? CDM JESD22-C101E exceeds 1000 V for both ports

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

? Available in X2SON8 package

? Specified from ?40 ?C to +125 ?C

Applications

? I2C/SMBus, UART

? GPIO
