Logic - Translators, Level Shifters

The SY100S391JZ-TR is a bidirectional level translator suitable for 1.8 V to 3.6 V and 2.5 V to 3.6 V logic level translation (VCCL/VCCA, VCCH). This device supports all four voltage combinations (1.8 V to 2.5 V and 2.5 V to 1.8 V, 1.8 V to 3.6 V and 3.6 V to 1.8 V, and 2.5 V to 3.6 V and 3.6 V to 2.5 V). It is designed with the small-sized packages and is ideal for products requiring a small component footprint.

The SY100S391JZ-TR is a logic translator that is used for level shifting and/or voltage level conversion between interfaces. This device acts as a bridge between two different logic levels and also supports a wide range of voltages from 1.8V to 3.6V and 2.5V to 3.6V respectively. The SY100S391JZ-TR provides a simple and low-power solution to complex systems that require level shifting or interface conversion.

Working Principle

The SY100S391JZ-TR operates in an active low configuration when used in logic level shifting applications. This device uses two CMOS pass transistors, a low-side pass transistor (L1) and a high-side pass transistor (H2). Circuitry is provided to ensure that outputs remain low until the L1 and H2 transistors are completely turned on.

The L1 and H2 input is controlled by a level-shift control signal (LEVEL SHIFT). When this signal is low, both transistors are cut off and no voltage is passed to the output. When this signal is high, the transistors are turned on, allowing the output voltage to be equal to the input voltage. The voltage level is determined by the input voltage, which could be either 1.8 V to 3.6 V or 2.5 V to 3.6 V.

The SY100S391JZ-TR has output disable (OD) and input disable (ID) pins. The ID pin is used to control the input current. When the ID pin is asserted, it sets the output voltage to a high impedance state. The OD pin is also asserted to disconnect the output line from the input line, thus further reducing power consumption. In this way, it helps in keeping the static power dissipation of the device to its minimum.

Applications

The SY100S391JZ-TR is suitable for driving and interfacing the logic busses in advanced automotive applications, such as infotainment systems and driver information systems. It is used for translating RTL logic memory and enable/data signals to TTL logic used in bus systems. This device is also ideal for interfacing high speed memories and parallel buses used in audio engine control applications.

The SY100S391JZ-TR also finds its application in USB 2.0 and USB 3.0, video interfaces, network switches, power management systems, audio codecs, FPGA Interfaces, and wireless communication protocols such as Bluetooth LE, ZigBee, and Wi-Fi.

To conclude, the SY100S391JZ-TR is an effective logic translator that supports differentvoltage levels. This makes it an ideal solution for various memory and interface conversion applications, such as automotive, audio, and communication.
