This Product Selection Guide contains information to help select products in the Multivibrators category on

Multivibrators are simple two-state devices commonly considered digital logic components, though their typical manners of use are largely analog in character. Monostable types, also called “one-shots”, have one stable state; though application of a trigger signal can cause them to leave this state for a period of time usually determined by the value of a connected capacitor. These are useful for applications such as de-bouncing switch contacts. Astable types have no stable state, and transition between two states continuously at a frequency which again is usually determined by the value of a connected capacitor.


Logic Type: Describes the logic functions used within the circuit.

Independent Circuits: Indicates the number of identical functional elements that are incorporated into a device. While inputs and outputs of each element are addressable separately, all elements typically share a common power supply connection.

Schmitt Trigger Input: Indicates whether or not a device incorporates an input hysteresis mechanism. Typically used to avoid spurious outputs caused by noisy or slow-changing input signals.

Propagation Delay: Characterizes the time delay between assertion of an input and the appearance of a result at a device’s output.

Current - Output High, Low: The maximum recommended current flow through a device’s output pin. Multiple values reflect ratings that differ depending on direction of current flow.

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.

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.

Mounting Type: Indicates how the device is attached.

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.
