Programmable Timers And Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct packaging and material specifications. Confirm that the CDIP package variant matches the design requirements for thermal management and mechanical fit. Cross-reference the active production status with the latest datasheet revision history.

Programmable Timers And Oscillators Selection Notes

Select this component when dual independent timers are required in a military-grade or high-temperature environment. Ensure the supply voltage remains between 4.5V and 18V. Consider the 10µs minimum monostable pulse duration limitation. Verify that the load capacitance does not exceed 15pF for specified switching characteristics.

Programmable Timers And Oscillators Part Context

This part belongs to the SE556 family, which provides enhanced performance over standard commercial variants. It shares functional compatibility with NA556, NE556, and SA556 devices but offers an extended operating temperature range suitable for demanding applications. The device integrates two complete 555-timer circuits into one package.

Programmable Timers And Oscillators FAQ

What is the minimum monostable pulse duration?

The minimum monostable pulse duration is 10µs due to comparator storage time limitations.

How does the RESET input function?

The RESET input overrides all other inputs; when low, it forces the output and discharge switch low.

What is the maximum output current?

The output can source or sink up to 200mA.
