1 General description

The NTS0304E is a 4-bit, dual supply translating transceiver family with auto direction sensing, that enables

bidirectional voltage level translation. It features eight 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.

2 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 and OE inputs accept voltages up to 3.6 V and are 3.6 V tolerant

• B-side inputs accept voltages up to 5.5 V and are 5.5 V tolerant

• ESD protection:

– IEC 61000-4-2 Class 4, 8 kV contact for B-side port

– 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

• Package options: TSSOP14 and WLCSP12

• Specified from -40 °C to +125 °C
