NXS0104 Dual Supply Translating Transceivers Nexperia NXS0104 Dual Supply Translating Transceivers are 4-bit, open drain, and auto direction sensing devices that enable bi-directional voltage level translation. These transceivers feature two 4-bit input-output ports (An and Bn), one Output Enable input (OE), and two supply pins (VCC(A) and VCC(B)). The Nexperia NXS0104 transceivers are fully specified for partial-power-down applications using IOFF. The IOFF circuitry disables the output, preventing the damaging backflow current through the device when powered down. These transceivers are ideally used in desktop PC, handsets, smartphones, and tablets.
