NXP Semiconductors NTS0302 and NTS0304E Translating Transceivers are 2-bit and 4-bit dual-supply, bi-directional level translators, available now from Mouser. The devices provide auto direction sensing, allowing bi-directional voltage level translation with no requirement for direction control. These devices are intended to address the many applications that require a transition of voltage signals through various domains. With auto-direction sensing and the ultra-low 0.95V minimum voltage supply, the transceivers match up well with low voltage MCUs and FPGAs.
The 2-bit NTS0302E features two 1-bit input-output ports (A and B). The 4-bit NTS0304E offers eight 1-bit input-output ports (A and B). Both devices provide one Output Enable input and two supply pins (VCC(A) and VCC(B)). VCC(A) can be provided at any voltage between 0.95V and 3.6V. VCC(B) can be provided at any voltage between 1.65V and 5.5V. This flexibility makes the device ideal for translating among any of the voltage nodes (0.95V, 1.2V, 1.8V, 2.5V, 3.3V, and 5V). 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 understand a high-impedance OFF-state.
