74LCX126SJX is a logic-level translator designed for 12.5V to 3.6V translation. It works with slow edge rates and provides improved noise immunity when compared to logic translator LVTTL (low voltage transistor-transistor logic). It is available in a variety of packages including the TSSOP-16. It provides full compatibility with all popular logic families including CMOS, TTL, and HCT.
Application field and working principle
In its most basic form, the 74LCX126SJX is an excellent choice for level shifter applications. By using the 74LCX126SJX, the user can easily interface two electronic devices with two different logic levels. An example of this would be a computer to an LCD display with a logic level of five volts and the machine connected to that LCD display having a logic level of three volts. The 74LCX126SJX allows electrical signals to be translated from one logic level to another.
The 74LCX126SJX includes three independent switches that are controlled by the control input. When the select input is low (0V) each of the outputs assumes the logic level of the inputs (Vcc0 and/or Vcc1). When the select input is high (3.6V), the 74LCX126SJX acts as an open switch. Thus, the 74LCX126SJX will drive the outputs to their default state regardless of the states of the input buffers.
The 74LCX126SJX also features robust ESD protection for the inputs and outputs. This protection is provided by a series diode and a diode from each input to ground. These ESD protection diodes provide additional protection from ESD voltages that are steady or varying so that the device will not be damaged. The 74LCX126SJX also includes a high speed latch which is used to prevent data loss and ensures that the outputs switch quickly.
The 74LCX126SJX can be used in both directions, allowing it to function as both a level shifter, allowing signals to be translated from one logic level to another and as a level translator, allowing signals to pass between two logic levels. This makes it an excellent choice for interface application where two devices with different logic levels are connected.
In addition to level shifter and level translator applications, the 74LCX126SJX can be used in a variety of other applications where fast and reliable data IO is required. These include display drivers, motor control systems, switch matrixes and FET driver applications.
The 74LCX126SJX is a great choice for applications that require fast and reliable logic level translation. Its low power consumption and robust ESD protection make it an excellent choice for portable and energy conscious applications. It is also capable of operating over a wide range of temperatures, making it suitable for use in harsh industrial environments.
