It can be used asa direct replacement of the standard 555 in applications working from -55°C to +175°Cor it can be used in a larger package in order to make use of the enhanced capabilities. These capabilities include the presence of a pin that provides a voltage decreasing linearly with the die temperature as well as a bank of four binary-weighted capacitors from 20pF to 160pF. Because of its high input impedance, this device allows the use of smaller capacitors than those used by the standard 555, then providing more accurate time delays and oscillations, as well as cheaper BOM. The CMT-555 can be used throughout the-55°C to + 175°C temperature range. | Features\u003Cbr>• Supply voltage 5V +/-10%\u003Cbr>• Low supply current\u003Cbr>• Timing from microseconds to hours\u003Cbr>• Operates in both monostable and astable modes\u003Cbr>• Highly stable timing characteristics with temperature and supply voltage\u003Cbr>• On-chip temperature sensor-1.47mV/°C\u003Cbr>• Validated at 175°C for 30000 hours (and still on-going)\u003Cbr>• Available in several standard packages\u003Cbr>Applications\u003Cbr>• Well logging, Automotive, Aeronautics & Aerospace\u003Cbr>• Precision timing\u003Cbr>• Pulse generation\u003Cbr>• Pulse width and pulse position modulation |\n| --- | --- |\n\nPackaging and Pin Description  \nVSS /TRIGGER OUTPUT /RESET  \nPSOIC8  \nVDD DISCHARGE THRESHOLD CNTRL_V  \n\n| Pin \\# | Pin Name | Pin Description |\n| --- | --- | --- |\n| 1 | VSS | Ground terminal. |\n| 2 | /TRIGGER | Sets the output with a falling edge. |\n| 3 | OUTPUT | Main output. |\n| 4 | /RESET | Main reset.
