HT7500 General Description
The HT7500 is a CMOS digital clinical thermometer IC for measuring body temperature in Centigrade (C) or Fahrenheit (F) mode by its bonding option. It also provides alarm and auto power off functions. The other electronic components are LCD display, thermister, 1.5V battery, ON/OFF switch, buzzer, resistors and capacitors.
HT7500 Maximum Ratings
Supply voltage ................................0V to 2.0V
Input voltage ...............VSS-0.5V to VDD+0.5V
Operation Temperature ...........-2.0 to +75
Storage Temperature .............-55 to +125
Note: These are stress ratings only. Stresses exceeding the range specified under "Absolute MaximumRatings " may cause substantial damage to the device. Functional operation of this device at other conditions beyond those listed in the specification is not implied and prolonged exposure to extreme conditions may affect device reliability.
