SE555JG

Programmable Timers And Oscillators Overview

The SE555JG is a precision timer integrated circuit manufactured by Texas Instruments, belonging to the SE555 series. It features a single timer configuration housed in an 8-pin CDIP (Ceramic Dual In-Line Package) designed for through-hole mounting. The device operates within a supply voltage range of 4.5 V to 18 V and supports a wide operating temperature range from -55°C to +125°C. Key electrical specifications include a typical supply current of 4 mA, with output drive capabilities of 200 mA high-level and -200 mA low-level currents.

Programmable Timers And Oscillators Feature Summary

• Precision timing performance with TTL-compatible outputs

• Extended military-grade temperature range (-55°C to +125°C)
• High current sink/source capability of ±200 mA

Programmable Timers And Oscillators Applications

• Precision time delay generation
• Pulse generation circuits
• DC-AC oscillation applications
• Temperature sensing and measurement systems

Programmable Timers And Oscillators Part Context

The SE555JG is part of the SE555 family of precision timers. The 'SE' prefix typically denotes military-grade or high-reliability variants compared to commercial counterparts like the NE555. The 'JG' suffix indicates the ceramic DIP package style. This component serves as a direct functional replacement for other standard 555 timer ICs where higher reliability and wider temperature tolerance are required.

Programmable Timers And Oscillators Replacement Considerations

Direct pin-compatible replacements include the NE555JG and SN55555JG. When substituting, verify that the lower supply voltage minimum (2V for TLC555 or 4.5V for NE555) meets system requirements, as the SE555 requires at least 4.5V. Ensure the replacement package matches the 8-pin CDIP footprint.
