Frequently Asked Questions
What is the supply voltage range for the SE556JB?
The SE556JB operates over a wide supply voltage range from 5V to 15V, and it can also operate from a 15V nominal supply. This flexibility makes it suitable for both TTL-compatible and standard analog system designs without requiring additional voltage regulation.
How many timer channels does the SE556JB contain?
The SE556JB contains two independent 555-type timer channels (Number of Functions: 1 dual timer) integrated into a single 14-pin ceramic DIP package. Each channel can be configured independently in astable or monostable mode, allowing designers to implement two separate timing functions with one component.
What package type does the SE556JB use and what are its dimensions?
The SE556JB uses a 14-pin ceramic glass-sealed dual in-line package (DIP14, 0.3-inch row spacing), designated by JESD-30 code R-GDIP-T14. The ceramic construction provides superior moisture resistance and mechanical durability compared to plastic DIP packages, making it well-suited for military and high-reliability applications.
What waveform types can the SE556JB generate?
The SE556JB can generate pulse and rectangular waveforms, as indicated by its Analog IC type designation PULSE; RECTANGULAR. In astable mode it produces continuous square or rectangular oscillations, while in monostable mode it generates a single timed output pulse with duration determined by external RC components.
Is the SE556JB RoHS compliant and lead-free?
Yes, the SE556JB carries a Pbfree Code of Yes and a JESD-609 Code of e0, confirming it is manufactured without lead and meets RoHS environmental compliance requirements. This makes it suitable for modern electronics assembly using lead-free soldering processes while maintaining the high reliability of its ceramic package.
