We now move on to translation use cases with different interface standards requiring different devices. Broadly the interface standards can be classified into open drain and push/pull. Open drain interface examples include I2C, MDIO, SMBus, among others. Push/pull interface examples include SPI, UART, JTAG, I2S, SD, [INAUDIBLE], et cetera.
Based on the open Draymond interface like I2C or MDIO, we recommend using TXS or the LSF auto bidirectional translation devices. For the push/pull interfaces, we recommend using direction-controlled devices, like AVC4T774, LVC8T245, and the most recently released AXC family of devices, or the buffer the TXB family of auto bidirectional translation devices.
We are coming up with a new device sampling from first half of 2018 called the 2N7001T. This is a single channel unidirectional translation device with dual [? vaulted ?] supplies operating from 1.8 to 3.3 volts. This offers a convenient option to replace the discrete FETs which is used in conjunction with the additional pull-up resistors for up or down translation. It is offered in the tiny 0.64 millimeters square x2 [INAUDIBLE] DPW package, as well as the standard leaded SOT DCK package. With the 12 milliamps drive on the output channel, it can also be used as a unidirectional buffer to drive LEDs as shown on the right.
