7603901FA

Overview

The Texas Instruments 7603901FA is a dual-element monostable multivibrator from the SN54LS123 family. It operates within an extended temperature range of -55°C to 125°C and utilizes a 16-pin CFP (Ceramic Flat Pack) package. The device features a typical pulse width adjustment time of 34 ns. It supports retriggerable operation, allowing for flexible timing control in digital circuits.

Feature Summary

• Dual-element monostable multivibrator configuration
• Retriggerable operation capability
• Extended military-grade temperature range
• High-speed pulse width generation

Applications

• Timing delay circuits
• Pulse width modulation
• Frequency division
• Waveform shaping

Procurement Notes

Verify the specific suffix 'FA' corresponds to the ceramic flat pack variant with leaded construction. Confirm the manufacturer source is Texas Instruments or an authorized distributor. Ensure the component meets the required -55°C to 125°C operating temperature specifications for your application environment.

Selection Notes

Select this component when dual independent monostable circuits are required in harsh environments. The LS logic family offers standard speed performance. Consider the 16-CFP package constraints for PCB layout. Verify compatibility with existing TTL logic levels if interfacing with other digital components.

Part Context

This part belongs to the SN54LS123 series of retriggerable monostable multivibrators. It is designed for high-reliability applications requiring extended temperature stability. The dual-element design allows for two separate timing functions within a single package, saving board space compared to using two single-channel devices.

Replacement Considerations

Direct substitutes include other SN54LS123 variants from Texas Instruments or equivalent parts from manufacturers like ON Semiconductor or Fairchild, provided they match the 16-CFP package and military temperature rating.
