Programmable delay timer with oscillator
FEATURES Positive and negative edge triggered Retriggerable or non-retriggerable Programmable delay minimum: 100 ns maximum: depends on input frequency and division ratio Divide-by range of 2 to 224 Direct reset terminates output pulse Very low power consumption in triggered start mode 3 oscillator operating modes: – RC oscillator – Crystal oscillator – External oscillator Device is unaffected by variations in temperature and VCC when using an external oscillator Automatic power-ON reset Schmitt trigger action on both trigger inputs Direct drive for a power transistor Low power consumption in active mode with respect to TTL type timers High precision due to digital timing Output capability: 20 mA ICC category: MSI. APPLICATIONS Motor control Attic fan timers Delay circuits Automotive applications Precision timing Domestic appliances. CI CPD Notes QUICK REFERENCE DATA GND = 0 V; Tamb = 25 °C; tr = tf = 6 ns.
