TLC7524CDR Equivalent & Substitute Parts

Part Overview

The TLC7524CDR is an 8-bit digital-to-analog converter manufactured by Texas Instruments, housed in a 16-SOIC surface mount package. This component functions as a current-output DAC with external reference capability, designed for data acquisition applications requiring parallel digital input and unbuffered current output. The part maintains active product status with substantial inventory availability (29,572 units in stock). Equivalent and substitute parts are identified based on matching electrical specifications, package compatibility, and functional equivalence to support design flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLC7524CDR are qualified based on the following electrical and mechanical parameters:

• Resolution: 8-bit digital-to-analog conversion capability
• Output Configuration: Current-output, unbuffered topology
• Data Interface: Parallel digital input
• Reference Input: External reference requirement
• Converter Architecture: R-2R resistor ladder network
• Package Compatibility: 16-SOIC surface mount form factor with 0.154" (3.90mm) width
• Operating Temperature Range: 0°C to 70°C
• Supply Voltage Compatibility: Analog and digital supply voltage ranges supporting 5V operation
• Compliance: ROHS3 compliance and REACH unaffected status

The substitute parts MX7524JCSE+, MX7524KCSE+, and MX7524LCSE+ (all manufactured by Analog Devices Inc./Maxim Integrated) meet these core substitution criteria. All candidates share identical bit resolution, output type, data interface, reference architecture, package geometry, and temperature operating range. Variations in settling time and INL/DNL specifications remain within acceptable tolerance ranges for functional equivalence in most data acquisition applications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status with current manufacturing support. The MX7524JCSE+, MX7524KCSE+, and MX7524LCSE+ variants are fully compliant with ROHS3 requirements and REACH regulations, matching the environmental and regulatory posture of the TLC7524CDR.

The primary electrical distinction between the TLC7524CDR and the Maxim substitute parts is settling time: the TLC7524CDR specifies 100ns while the MX7524 variants specify 500ns. This difference reflects different internal circuit implementations but does not affect functional compatibility in applications where settling time requirements do not exceed 500ns. The substitute parts demonstrate improved DNL specification (±1 LSB maximum versus ±2.5 LSB maximum), providing superior linearity performance.

Supply voltage specifications differ in presentation: the TLC7524CDR lists discrete voltage points (5V and 14.5V ~ 15.5V), while the MX7524 variants specify continuous ranges (5V ~ 15V). Both approaches support standard 5V and ±15V dual-supply configurations common in data acquisition circuits.

Component selection should be based on application-specific settling time requirements and inventory availability. All parts are electrically and mechanically interchangeable within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can MX7524JCSE+, MX7524KCSE+, and MX7524LCSE+ be used as direct replacements for TLC7524CDR?

A: Yes, within applications where the 500ns settling time specification is acceptable. All parts share identical 8-bit resolution, R-2R architecture, parallel data interface, external reference configuration, 16-SOIC package geometry, and operating temperature range. Electrical and mechanical compatibility is confirmed across all specified parameters.

Q: What is the significance of the different settling time specifications?

A: Settling time defines the duration required for the DAC output to stabilize within a specified error band following a digital input change. The TLC7524CDR specifies 100ns settling time, while the MX7524 variants specify 500ns. Applications requiring faster output settling must use the TLC7524CDR. Applications with settling time requirements of 500ns or greater can use either part without performance degradation.

Q: Are there differences in supply voltage requirements between the main part and substitutes?

A: Both the TLC7524CDR and MX7524 variants support 5V single-supply and ±15V dual-supply configurations. The TLC7524CDR specifies discrete voltage points (5V and 14.5V ~ 15.5V), while the MX7524 variants specify continuous ranges (5V ~ 15V). This represents different specification methodologies for the same operational voltage compatibility.

Q: Do the substitute parts require different PCB layout or circuit design modifications?

A: No. The MX7524JCSE+, MX7524KCSE+, and MX7524LCSE+ are pin-compatible with the TLC7524CDR in the 16-SOIC package. No circuit modifications or PCB redesign is required for substitution. Standard data acquisition circuit topologies using external reference inputs and parallel digital control remain unchanged.

Q: What is the difference between MX7524JCSE+, MX7524KCSE+, and MX7524LCSE+?

A: All three variants share identical electrical specifications, package configuration, and functional characteristics. The letter designation (J, K, L) typically indicates different temperature grade or performance grade classifications within the Maxim product line. For applications operating within the 0°C to 70°C range, all three variants are functionally equivalent.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The MX7524JCSE+, MX7524KCSE+, and MX7524LCSE+ are all ROHS3 compliant and REACH unaffected, matching the environmental compliance status of the TLC7524CDR.
