NA555S-13

Programmable Timers And Oscillators Overview

The NA555S-13 is a precision timer IC from Diodes Incorporated, part of the NE555/SA555/NA555 family. It operates within a supply voltage range of 4.5V to 16V and supports an ambient temperature range of -40°C to 105°C. The device features a TTL-compatible output capable of sourcing or sinking up to 200mA. Key electrical characteristics include a typical threshold voltage of 10V at 15V supply and 3.3V at 5V supply, with a maximum threshold current of 250nA. The trigger voltage typically measures 5V at 15V supply and 1.67V at 5V supply. Supply current ranges from 3mA to 15mA depending on the load state.

• Extended industrial temperature range (-40°C to 105°C)
• Totally lead-free and fully RoHS compliant

Programmable Timers And Oscillators Applications

• Time delay generation in monostable mode
• Oscillation frequency control in astable mode
• Pulse width modulation circuits
• Missing pulse detection systems

Programmable Timers And Oscillators Procurement Notes

Verify the operating temperature grade matches application requirements, as the NA555 variant specifies -40°C to 105°C compared to other family members. Confirm packaging details align with production needs, noting the standard tape and reel quantity is 2500 units. Ensure compliance with specific automotive change control protocols if required for the end-use environment.

Programmable Timers And Oscillators Selection Notes

Select the NA555S-13 when an extended industrial temperature range is necessary, distinguishing it from the commercial NE555 (0°C to 70°C) and automotive SA555 (-40°C to 85°C). Consider the 200mA output drive capability for direct interfacing with loads without additional buffering. Evaluate timing resistor values against leakage current specifications to ensure accuracy over the full temperature range.

Programmable Timers And Oscillators Part Context

This component belongs to the widely used 555 timer family produced by Diodes Incorporated. The 'N' designation indicates the industrial temperature grade variant. The '-13' suffix denotes the specific tape and reel packaging configuration with a quantity of 2500 units per reel. It shares pinout and functional compatibility with other 555 timers while offering specific thermal performance characteristics.

Programmable Timers And Oscillators Replacement Considerations

Direct pin-to-pin replacements include the NE555S-13 and SA555S-13 from the same manufacturer, provided temperature constraints are met. Other manufacturers' 555 timers may be functionally compatible but require verification of electrical parameters such as output drive current and supply voltage limits.
