The SN75LVCP412RTJT device is an interface product within the signal buffers, repeaters, splitters category. When dealing with LVDS or CML signal transmission applications that require ultra low power consumption, the SN75LVCP412RTJT provides the ideal choice for interfacing between components operating on different power supplies with 3.3V and 5V logic.

The SN75LVCP412RTJT resolves the power supply differences offering a guaranteed 5000Vrms of I/O isolation when operated within its operating temperature of -40°C to +85°C. It converts signals between differential and TTL voltage levels, with the data protocol remaining unchanged. The serial or parallel data protocol is determined by the selection of the OE logical inputs.

The device is robust enough for NEBS level 3 and 5 compliance, making it suitable for use in telecommunications, computing and industrial applications. The SN75LVCP412RTJT uses advanced system-level isolation technologies and its package minimizes board size allowing for maximum system density and flexibility.

The SN75LVCP412RTJT is a four channel, TTL/LVDS interface with a total current output capability of 6.5mA max for each LVDS channel. It offers rail-to-rail operation at the TTL side designed for 3.3V and 5V logic levels. Its reliable performance comes from its high speed of 140MHz, wide common-mode input range of 250mV to 750mV, and low power consumption of 1.2mA max. This device comes in a space saving VQFN-20 surface mount package.

When operating the SN75LVCP412RTJT, a differential input level of 300mV, typically, will be received. This differential input level will be converted to a single-ended input level which can be any voltage between 1.8V and 3.6V. On the output side, the TTL logic level 1 x LOW is 0.4V max and the 1 x HIGHD is 2.4V min. This output voltage can then be converted to a differentially tuned output.

When looking at the SN75LVCP412RTJT\'s functionality, the 3.3V input will be provided with internal level shifting for receiving with the logic levels. The 5V input logic is not level shifted and the logic voltage is not always compatible with the 3.3V system. The ON / OFF enable and 4-bit enable logic enable the logic levels to be converted. The output voltage depends on the enable logic input, when the logic is inactive, the output voltage is at 0V. The enable logic can be applied either in parallel or in serial configuration.

The SN75LVCP412RTJT is designed to be highly reliable, with its built in slew rate control and Schmitt trigger inputs. The device also offers latch-up protection and ESD IEC/EN 61000-6-2 Controlled environment criteria over high humid conditions. The device operates at up to 150MHz, allowing for faster data transmission. The SN75LVCP412RTJT is proven highly reliable, making it suitable for various applications such as audio/video interfaces, optical data transmission, and high speed drive interconnects between backplanes and hard disk drives like SCSI, SAS and Fibre Channel.

By considering all these features, it is easy to notice the SN75LVCP412RTJT is the ideal choice for any application that requires an interface between 3.3V and 5V logic levels, with low power consumption and a small form factor size. The device provides high speed, and 4-bit enable logic while maintaining a guaranteed 5000Vrms of I/O isolation over a wide range of operating temperatures.
