Product data sheet
1. General description
The NTBA104 is a 4-bit, dual supply translating transceiver with auto direction sensing,
that enables bidirectional voltage level translation. It features two 4-bit input-output ports
(An and Bn), one output enable input (OE) and two supply pins (V
CC(A)
and V
CC(B)
). V
CC(A)
can be supplied at any voltage between 1.2 V and 3.6 V and V
CC(B)
can be supplied at any
voltage between 1.65 V and 5.5 V, making the device suitable for translating between any
of the low voltage nodes (1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V and 5.0 V).
Pins An and OE are referenced to V
CC(A)
and pins Bn are referenced to V
CC(B)
. A HIGH
level at pin OE causes the outputs to assume a high-impedance OFF-state. This device is
fully specified for partial power-down applications using I
OFF
. The I
OFF
circuitry disables
the output, preventing the damaging backflow current through the device when it is
powered down.
2. Features and benefits
Wide supply voltage range:
V
CC(A)
: 1.2 V to 3.6 V and V
CC(B)
: 1.65 V to 5.5 V
I
OFF
circuitry provides partial Power-down mode operation
Inputs accept voltages up to 5.5 V
ESD protection:
HBM JESD22-A114E Class 2 exceeds 2500 V for A port
HBM JESD22-A114E Class 3B exceeds 15000 V for B port
MM JESD22-A115-A exceeds 200 V
CDM JESD22-C101E exceeds 1500 V
Latch-up performance exceeds 100 mA per JESD 78B Class II
