NTB0104GU12,115

Translators, Level Shifters Overview

The NTB0104GU12,115 is a 4-bit dual supply translating transceiver with auto direction sensing and 3-state outputs. It features two 4-bit input-output ports (An and Bn), an output enable input (OE), and two supply pins (VCC(A) and VCC(B)). VCC(A) operates between 1.2 V and 3.6 V, while VCC(B) operates between 1.65 V and 5.5 V. The device supports bidirectional voltage level translation between low voltage nodes such as 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 forces the outputs into a high-impedance OFF-state.

Translators, Level Shifters FAQ

How does the NTB0104 handle data flow direction?

The device features auto direction sensing, meaning it does not require an extra input signal to control the direction of data flow between port A and port B.

What happens when the OE pin is set to a LOW level?

A LOW level at pin OE causes the outputs to assume a high-impedance OFF-state.

Can the device be used in partial power-down applications?

Yes, the device is fully specified for partial power-down applications using IOFF circuitry, which disables the output to prevent damaging backflow current when powered down.
