The SN74GTLP1394PWRE4 is a 5-Channel Level-Shifter and Logic-Translator IC which is able to convert transistor logic to LVTTL logic and vice-versa. It is ideal for use in applications requiring high speed data transfer from low voltage TTL logic to high voltage LVTTL logic, and/or LVTTL logic to low voltage TTL logic in automotive and industrial applications. The device provides free flow of currents in both directions for safe, reliable operation.

The device supports 5 channels and is available in two packages, both of which are through-hole packages. It is optimized for a wide operating temperature range, making it suitable for automotive and industrial applications. It is also able to operate over a wide range of supply voltages, including 1.8 V, 2.5 V and 3.3 V. It also features a maximum switching frequency of 400MHz, allowing high speed transmission.

In terms of applications, the SN74GTLP1394PWRE4 is well-suited for use in automotive, industrial and medical systems, as well as computer systems and IoT related products. Specifically, it can be used for level-shifting for communication between a low voltage (1.5V-3.3V) and a near-5V supply line. Additionally, applications include voltage shift from bus masters to slave devices, such as in data buses or in general communication systems.

The SN74GTLP1394PWRE4 is equipped with a number of characteristics that help ensure reliable operation. Its 5 channels have an input-output delay of ≤ 50ns, which helps minimize propagation delay. It also has a logic high input voltage threshold of 1.4V to 3.0V, meaning it can easily detect a logic 0 or 1. This can be useful, for example, in communication between bus masters and slaves, where minimum delay is important.

In terms of working principle, the device is based on the concept of Transistor-Transistor Logic (TTL) with simultaneous switching and minimal power consumption. Essentially, it acts as a bidirectional translator which translates between Low-Voltage TTL (LVTTL) logic and transistor logic. The device is able to handle two directions, each functioning as a logic level-shifter/translator between two voltages. In other words, when going from low voltage to high voltage, the device works as a logic level-shifter, while going from high voltage to low voltage, it functions as an inverting level-shifter/translator.

Overall, the SN74GTLP1394PWRE4 is an ideal choice for applications that require high speed data transmission from low voltage TTL logic to high voltage LVTTL logic, or LVTTL logic to low voltage TTL logic. Its 5 channels support a maximum switching frequency of 400MHz, and it has a logic high input voltage threshold of 1.4V to 3.0V. Additionally, it features a low input-output delay of ≤ 50ns, which can prove useful in communication between bus masters and slaves.
