... The high 30 MHz clock frequency makes the device suitable for high data rate transmission. The thermal shutdown (170°C with about 15°C hysteresis) assures protection from overtemperature events. The STP16CPC26 is housed in four different packages: QSOP-2, SO-24, TSSOP-24 and HTSSOP-24 (with exposed pad). Package SO-24 ...

... Thermal shutdown 10 Thermal shutdown The STP16CPC26 is featured with a thermal shutdown. This protection is triggered if the junction temperature reaches 170°C. When the thermal shutdown is activated, all outputs are turned off independently on the data latched. Once the temperature decreases (thermal shutdown hysteresis is typically 15°C), the outputs are enabled again and the device keeps on working ...
