NXP ICM7555CD/01,112, General Purpose Timer 0.5MHz, 8-Pin SOIC
3,50 EUR
The ICM7555 is a CMOS timer providing significantly improved
performance over the standard NE/SE555 timer, while at the same
time being a direct replacement for those devices in most
applications. Improved parameters include low supply current, wide
operating supply voltage range, low THRESHOLD, TRIGGER, and
RESET currents, no crowbarring of the supply current during output
transitions, higher frequency performance and no requirement to
decouple CONTROL VOLTAGE for stable operation.
FEATURES
• Exact equivalent in most applications for NE/SE555
• Low supply current: 80μA (typ)
• Extremely low trigger, threshold, and reset currents: 20pA (typ)
• High-speed operation: 500kHz guaranteed
• Wide operating supply voltage range guaranteed 3 to 16V over full
automotive temperatures
• Normal reset function; no crowbarring of supply during output
transition
• Can be used with higher-impedance timing elements than the
bipolar 555 for longer time constants
• Timing from microseconds through hours
• Operates in both astable and monostable modes
• Adjustable duty cycle
• High output source/sink driver can drive TTL/CMOS
• Typical temperature stability of 0.005%/o C at 25°C
• Rail-to-rail outputs
APPLICATIONS
• Precision timing
• Pulse generation
• Sequential timing
• Time delay generation
• Pulse width modulation
• Pulse position modulation
• Missing pulse detector
