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
