NLSX Bit 100 Mb/s Configurable Dual-Supply Level Translator

Transcription

1 4-Bit 00 Mb/s Configurable Dual-Supply Level Translator The NLSX304 is a 4 bit configurable dual supply bidirectional level translator without a direction control pin. The I/O and I/O ports are designed to track two different power supply rails, and respectively. The supply rail is configurable from.3 V to 4.5 V while the supply rail is configurable from 0.9 V to ( 0.4) V. This allows lower voltage logic signals on the side to be translated into higher voltage logic signals on the side, and vice versa. Both I/O ports are auto sensing; thus, no direction pin is required. The Output Enable () input, when Low, disables both I/O ports by putting them in 3 state. This significantly reduces the supply currents from both and. The signal is designed to track.

9 IMPORTANT APPLICATIONS INFORMATION Level Translator Architecture The NLSX304 auto sense translator provides bi directional voltage level shifting to transfer data in multiple supply voltage systems. This device has two supply voltages, and, which set the logic levels on the input and output sides of the translator. When used to transfer data from the to the ports, input signals referenced to the supply are translated to output signals with a logic level matched to. In a similar manner, the to translation shifts input signals with a logic level compatible to to an output signal matched to. The NLSX304 consists of four bi directional channels that independently determine the direction of the data flow without requiring a directional pin. The one shot circuits are used to detect the rising or falling input signals. In addition, the one shots decrease the rise and fall time of the output signal for high to low and low to high transitions. Input Driver Requirements For proper operation, the input driver to the auto sense translator should be capable of driving 2.0 ma of peak output current. Output Load Requirements The NLSX304 is designed to drive CMOS inputs. Resistive pullup or pulldown loads of less than 50 k should not be used with this device. The NLSX3373 or NLSX3378 open drain auto sense translators are alternate translator options for an application such as the I 2 C bus that requires pullup resistors. Enable Input () The NLSX304 has an Enable pin () that provides tri state operation at the I/O pins. Driving the Enable pin to a low logic level minimizes the power consumption of the device and drives the I/O and I/O pins to a high impedance state. Normal translation operation occurs when the pin is equal to a logic high signal. The pin is referenced to the supply and has Over Tolerant (OVT) protection. Uni Directional versus Bi Directional Translation The NLSX304 can function as a non inverting uni directional translator. One advantage of using the translator as a uni directional device is that each I/O pin can be configured as either an input or output. The configurable input or output feature is especially useful in applications such as SPI that use multiple uni directional I/O lines to send data to and from a device. The flexible I/O port of the auto sense translator simplifies the trace connections on the PCB. Power Supply Guidelines It is recommended that the supply should be less than or equal to the value of the minus 0.4 V. The sequencing of the power supplies will not damage the device during the power up operation; however, the current consumption of the device will increase if exceeds minus 0.4 V. The Enable () pin can be used to provide power savings. Both I/O ports are tri stated and in low power consumption state if the input equals 0 V. The enable pin should be used to enter the low current tri state mode, rather than setting either the or supplies to 0 V. The NLSX304 will not be damaged if either or is equal to 0 V while the other supply voltage is at a nominal operating value; however, the operation of the translator cannot be guaranteed during single supply operation. For optimal performance, 0.0 to 0. F decoupling capacitors should be used on the and power supply pins. Ceramic capacitors are a good design choice to filter and bypass any noise signals on the power supply voltage lines to the ground plane of the PCB. The noise immunity will be maximized by placing the capacitors as close as possible to the supply and ground pins, along with minimizing the PCB connection traces.
