Product data sheet
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
