This Product Selection Guide contains information to help select products in the Programmable Timers and Oscillators category on DigiKey.com
Programmable Timers and Oscillators are devices that can be set to provide timing pulses at a specified frequency.
SelectionCharacteristics
Type: Indicates the operational mode(s) of a featured IC, which has categorical significance for performance traits such as electrical efficiency.
Count: For devices programmable by means of adjusting a digital divider ratio, indicates the range over which this ratio may be adjusted.
Frequency: Describes a device’s nominal operating frequency or frequency range; the rate at which an input power source is switched in the course of the conversion process.
Voltage - Supply: Typically represented by a range, this indicates the low and high voltage limits which one can expect standard operation. Voltages outside this range may damage the device and other system components.
Current - Supply: This rating indicates the nominal amount of current you would expect the device to draw during normal operation.
Operating Temperature: Recommended operating temperature, typically given in a range or as a maximum. Exceeding these temperatures may affect performance or damage the device and other system components.
Package / Case: Indicates the type of protective case used on an electronic component to allow easy handling, installation, and protection. This selection was determined to be the closest industry standard applicable to the suppliers device packaging. Typically it is best to check the actual dimensions from the datasheet rather than depend on this terminology when designing your circuit.
Supplier Device Package: This is what the manufacturer calls the package of this device. They are manufacturer specific. It is typically best to use the actual dimensions from the datasheets rather than to go by this terminology when designing your circuit.
Mounting Type: Indicates how the device is attached.
