The LTC1555LEGN#PBF is a low-voltage, single supply, CMOS-based comparator programmed to provide logic levels when the input voltage is greater or less than a programmed threshold. It is ideal for applications with inputs ranging from 0V to 3.0V, making it suitable for use in low-voltage and mixed signal range both in AC and DC mode. Additionally, it is able to provide high noise suppression to protect against noise-induced false switching.

The LTC1555LEGN#PBF is a Logic Translator and Level Shifter, designed to provide voltage translation between TTL and CMOS logic levels. It operates from a single supply, allowing it to function in both TTL and CMOS logic families, as well as other logic families.

The LTC1555LEGN#PBF is a commercial-grade logic device. The chip is fabricated in 0.18μ m CMOS technology, combining excellent noise immunity and low power consumption. It features an on-chip long-term constant current voltage references and a wide input common-mode range, making it suitable for applications where precise levels of thresholds or threshold ratios are required, such as in industrial and automotive applications.

The LTC1555LEGN#PBF provides excellent electrical performance. It features a wide common-mode and differential-mode input range, high gain, large signal-to-noise ratio (SNR), fast response time, and low power consumption, making it the ideal choice for a variety of critical and sensitive applications.

Internally, the LTC1555LEGN#PBF is pre-programmed with logic levels for translation between TTL and CMOS logic. When the input voltage is greater or less than the pre-set threshold, it will output either a logic high or low. The device is also capable of detecting multiple logic levels, allowing it to adapt to various kinds of logic, like open-drain, totem-pole, and CMOS.

In addition to providing voltage translation, the LTC1555LEGN#PBF also features ESD protection which helps protect the device from electrostatic discharge, which can damage or destroy components, especially in high-voltage industrial environments. This ESD protection also assists with noise immunity, providing high levels of immunity to broadband noise sources, like RF noise generated by Electric and Magnetic fields.

Overall, the LTC1555LEGN#PBF is an excellent choice for a variety of low-voltage, single-supply, CMOS-based applications. Its wide input common-mode and differential-mode range, high gain, fast response time, high SNR, and low power consumption make it ideal for sensitive and critical applications. Additionally, its on-chip voltage reference and ESD protection further enhances its performance and makes it an excellent choice for industrial and automotive applications.
