SA555D Information

Description

Here's a concise introduction to the Texas Instruments SA555D: The SA555D is a precision timer from Texas Instruments, designed for operation in a temperature range of -55°C to 85°C. This SOIC-8 packaged device offers adjustable timing capabilities, allowing it to generate stable or monostable outputs. The duty cycle can also be adjusted to suit specific application requirements. A key feature of the SA555D is its TTL-compatible output, which can sink or source up to 200 mA. This makes it a versatile component suitable for various applications. Additionally, the SA555D meets military-grade standards (MIL-PRF-38535) on compliant products, ensuring tested parameters for specific markets. Overall, the SA555D is an industrial-grade timer offering flexibility in timing and output capabilities, making it a reliable choice for diverse projects.

Features

The SA555D features include:

  • Timing from microseconds to hours
  • Astable or monostable operation
  • Adjustable duty cycle
  • TTL-compatible output that can sink or source up to 200mA

These features make the SA555D a precision timer suitable for various applications, including timing and control circuits.

Package

The package type of SA555D is SOIC-8 (Small Outline Integrated Circuit - 8 pin).

Pinout

The SA555D is an 8-pin SOIC (Small Outline Integrated Circuit) package. Here's a concise summary of its pin functions: 1. VCC: Positive supply voltage 2. GND: Ground 3. OUT: Output signal 4. TRIG: Trigger input 5. RESET: Reset input 6. CONTROL: Control input for duty cycle adjustment 7. EXTCLK: External clock input (not used in astable mode) 8. THRESHOLD: Threshold input for monostable operation Please note that this information is based on the provided product description and may not be a comprehensive or authoritative source of information about the SA555D.
