Product data sheet
1. General description
The NTB0104 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 (VCC(A) and VCC(B)). VCC(A)
can be supplied at any voltage between 1.2 V and 3.6 V and VCC(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 VCC(A) and pins Bn are referenced to VCC(B). A LOW
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 IOFF. The IOFF circuitry disables
the output, preventing the damaging backflow current through the device when it is
powered down.
