(2) Timing interval error is defined as the difference between the measured value and the average value of a random sample from each process run. (3) Values specified are for a device in a monostable circuit similar to Figure 9, with the following component values: RA = 2 kΩ to 100 kΩ, C = 0.1 μF. (4) On products compliant to MIL-PRF-38535, this parameter is not production tested. (5) Values specified are for a device in an astable circuit similar to Figure 12, with the following component values: RA = 1 kΩ to 100 kΩ, C = 0.1 μF. 6 Submit Documentation Feedback Copyright © 1973–2014, Texas Instruments Incorporated Product Folder Links: NA555 NE555 SA555 SE555 Document Outline 1 Features 2 Applications 3 Description 4 Simplified Schematic Table of Contents 5 Revision History 6 Pin Configuration and Functions 7 Specifications 7.1 Absolute Maximum Ratings 7.2 Handling Ratings 7.3 Recommended Operating Conditions 7.4 Electrical Characteristics 7.5 Operating Characteristics 7.6 Typical Characteristics 8 Detailed Description 8.1 Overview 8.2 Functional Block Diagram 8.3 Feature Description 8.3.1 Mono-stable Operation 8.3.2 A-stable Operation 8.3.3 Frequency Divider 8.4 Device Functional Modes 9 Applications and Implementation 9.1 Application Information 9.2 Typical Applications 9.2.1 Missing-Pulse Detector 9.2.1.1 Design Requirements 9.2.1.2 Detailed Design Procedure 9.2.1.3 Application Curves 9.2.2 Pulse-Width Modulation 9.2.2.1 Design Requirements 9.2.2.2 Detailed Design Procedure 9.2.2.3 Application Curves 9.2.3 Pulse-Position Modulation 9.2.3.1 Design Requirements 9.2.3.2 Detailed Design Procedure 9.2.3.3 Application Curves 9.2.4 Sequential Timer 9.2.4.1 Design Requirements 9.2.4.2 Detailed Design Procedure 9.2.4.3 Application Curves 10 Power Supply Recommendations 11 Device and Documentation Support 11.1 Related Links 11.2 Trademarks 11.3 Electrostatic Discharge Caution 11.4 Glossary 12 Mechanical, Packaging, and Orderable Information
