TLC7524ENG4 Equivalent & Substitute Parts

Part Overview

The TLC7524ENG4 is an 8-bit digital-to-analog converter (DAC) manufactured by Texas Instruments, housed in a 16-DIP package. This component features current output with unbuffered configuration, external reference capability, and R-2R architecture suitable for data acquisition applications. The TLC7524ENG4 is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain electrical and mechanical compatibility for ongoing system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLC7524ENG4 is determined by strict alignment of the following parameters:

• 8-bit resolution with single D/A converter
• Current output, unbuffered configuration
• Differential output capability
• Parallel data interface
• External reference type
• R-2R architecture
• 16-DIP through-hole package (0.300", 7.62mm)
• Operating temperature range of -40°C ~ 85°C
• ROHS3 compliance

All identified substitute parts meet these core requirements. Variations in settling time and supply voltage ranges are noted but do not preclude functional substitution within the specified operating parameters.

Parameter Comparison

Engineering Selection Recommendations

TLC7524EN is the primary substitute for the TLC7524ENG4. Both parts are manufactured by Texas Instruments, share identical electrical specifications including 100ns settling time and matched supply voltage ranges, and maintain full compatibility with existing PCB layouts and firmware implementations. TLC7524EN is currently in active production status with established supply availability.

AD7524JNZ, AD7524KNZ, and AD7524LNZ are functionally equivalent alternatives manufactured by Analog Devices Inc. These parts maintain the same 8-bit resolution, R-2R architecture, parallel interface, and 16-DIP package configuration. The primary electrical difference is increased settling time (500ns to 550ns versus 100ns), which is acceptable for applications where conversion speed is not a critical constraint. Supply voltage ranges are broader (5V ~ 15V) compared to the original specification. All three Analog Devices variants are in active production with confirmed inventory availability.

Selection between Texas Instruments and Analog Devices alternatives should be based on application timing requirements and existing supply chain relationships. All substitute parts maintain ROHS3 compliance and are suitable for the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can TLC7524EN be used as a direct replacement for TLC7524ENG4?

A: Yes. TLC7524EN is electrically and mechanically identical to TLC7524ENG4. Both are 8-bit DACs with 100ns settling time, identical supply voltage specifications, and 16-DIP through-hole packages. The primary difference is product status: TLC7524EN is in active production while TLC7524ENG4 is discontinued.

Q: What is the difference between the Texas Instruments TLC7524EN and the Analog Devices AD7524 variants?

A: All parts share the same 8-bit resolution, R-2R architecture, parallel interface, and 16-DIP package. The key difference is settling time: TLC7524EN settles in 100ns, while AD7524JNZ, AD7524KNZ, and AD7524LNZ settle in 500ns to 550ns. Supply voltage ranges also differ slightly, with Analog Devices parts accepting 5V ~ 15V versus Texas Instruments' 5V and 14.5V ~ 15.5V specifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. TLC7524EN, AD7524JNZ, AD7524KNZ, and AD7524LNZ are all ROHS3 compliant and suitable for applications requiring environmental compliance certification.

Q: Can I use an AD7524 variant if my application requires 100ns settling time?

A: No. AD7524JNZ, AD7524KNZ, and AD7524LNZ have settling times of 500ns to 550ns. If 100ns settling time is required, use TLC7524EN, which matches the original TLC7524ENG4 specification.

Q: Are there any package or pinout differences between these parts?

A: No. All substitute parts use the 16-DIP (0.300", 7.62mm) through-hole package with identical pinout. Direct PCB substitution is possible without layout modifications.

Q: What is the operating temperature range for all substitute parts?

A: All substitute parts operate across -40°C ~ 85°C, matching the original TLC7524ENG4 specification.
