The DS1877T+T&R is a digital temperature-sensing solution specifically designed to interface with digital circuits. This precision, low-voltage, low-power device combines a temperature sensor and dual TTL-level (transistor-transistor logic) logging circuitry with onboard threshold detection, featuring wide temperature range and open drain output, and low-power operation. The device has been employed in high-precision applications such as data monitoring and management in temperature-critical applications such as weather stations, equipment maintenance, and teletherapy.

The DS1877T+T&R features a wide temperature range between -55˚C and +125˚C, with 0.8˚C accuracy and can operate in both positive and negative bias voltage. It also features an open-drain output for multiplex control, a TTL logging output, and one-shot output and integration functions. Additionally, it has integral thermal sensing and a low-power standby mode reduces power consumption to less than 10uA.

The DS1877T+T&R is a versatile and highly accurate device, ideal for use in customized temperature sensing applications. It is an ideal device for digital temperature sensing, with a wide temperature range, low power operation, and high accuracy. It is also an ideal device for medical and scientific applications, as it can accurately measure and report temperature with great precision, while also providing threshold and logging functions.

The DS1877T+T&R is simple to use and very reliable, with few external components required for operation. The device features four independent operating modes: normal, standby, logging and one-shot.

In normal mode, the device continuously reports the temperature, with 8-bit resolution. The temperature data is output at the open drain output. Additionally, there is a TTL output that allows for logging and multiplexing of the temperature data.

In Standby mode, the device enters standby mode and reduces its power consumption to less than 10uA. This feature extends battery life and decreases power consumption.

In logging mode, the device records temperature values exceeding the device’s programmed high and low limits. These records are output at the open drain output and the TTL output. This is useful in medical and scientific applications, as it can be used to keep track of temperature measurements.

In one-shot mode, the device reads a single temperature value and then enters standby mode. This feature is ideal for intermittent temperature monitoring applications.

The DS1877T+T&R is a versatile temperature sensing solution for a variety of applications. Its wide temperature range and precision accuracy make it an ideal choice for temperature critical applications. Its thermal sensor, low power operation, and multiple operating modes make it useful for medical and scientific applications, as well as other applications requiring accurate temperature sensing.
