Operating Temperature

The operating temperature is the range of ambient temperature within which a power supply, or any other electrical equipment, operate in. This ranges from a minimum operating temperature, to a peak or maximum operating temperature, outside which, the power supply may fail.

-55°C ~ 125°C

Series

74HCT

Type

Multi-Voltage Supervisor

Max Operating Temperature

The Maximum Operating Temperature is the maximum body temperature at which the thermistor is designed to operate for extended periods of time with acceptable stability of its electrical characteristics.

85 °C

Min Operating Temperature

-40 °C

Max Power Dissipation

The maximum power that the MOSFET can dissipate continuously under the specified thermal conditions.

696 mW

4.5V ~ 5.5V

Number of Circuits

8-Bit

Max Supply Voltage

In general, the absolute maximum common-mode voltage is VEE-0.3V and VCC+0.3V, but for products without a protection element at the VCC side, voltages up to the absolute maximum rated supply voltage (i.e. VEE+36V) can be supplied, regardless of supply voltage.

5.5 V

Min Supply Voltage

The minimum supply voltage (V min ) is explored for sequential logic circuits by statistically simulating the impact of within-die process variations and gate-dielectric soft breakdown on data retention and hold time.

Number of Voltages Monitored

Voltage monitoring relays can detect not only under-voltages and over-voltages, but also voltage-related issues such as phase imbalances, phase loss, and phase sequence. Voltage monitoring relays are designed for either single-phase or three-phase systems.

Threshold Voltage

1.575 V

Undervoltage Threshold

During power up and power down, the UVLO function of the device has at least 0.1 V of hysteresis, but not more than 0.3 V. The UVLO function in power devices is a useful feature that enables robust system behavior across a wide range of operating conditions.

1.275 V

Overvoltage Threshold

Overvoltages are all voltages that temporarily surpass the threshold value of the mains voltage. However, overvoltages can not only occur in the 230 V (normal household power supply voltage) mains, but can also reach the connected devices via telephone or aerial cables.
