CMT-555 - HIGH TEMPERATURE RANGE 555 TIMER

General Description

The CMT-555 is an extended temperature range, low-power, highly stable device for generating accurate time delays or oscillation, with enhanced capabilities compared to the well known 555 timer.

Key Features

  • Supply voltage 5V +/-10%.
  • Low supply current.
  • Timing from microseconds to hours.
  • Operates in both monostable and asta- ble modes.
  • Highly stable timing characteristics with temperature and supply voltage.
  • On-chip temperature sensor -1.47mV/°C.
  • Validated at 175°C for 30000 hours (and still on-going).
  • Available in several standard packages.

The Leader in High Temperature Semiconductor Solutions CMT-555 DATASHEET Revision: 1.7 8-Aug-18 (Modified) HIGH TEMPERATURE RANGE 555 TIMER General Description The CMT-555 is an extended temperature range, low-power, highly stable device for generating accurate time delays or oscillation, with enhanced capabilities compared to the well known 555 timer. It can be used as a direct replacement of the standard 555 in applications working from -55°C to +175°C or 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.
