Product details
Overview
TL074MDEP from Texas Instruments is a quad JFET-input operational amplifier engineered for high-fidelity audio, precision analog signal conditioning, and defense-grade embedded systems. It delivers 13 V/μs slew rate, 18 nV/√Hz input voltage noise at 1 kHz, ±12 V maximum peak output swing (RL ≥ 2 kΩ), and operates across –55°C to 125°C. Its low 6 mV input offset voltage and 0.003% typical THD support high-accuracy preamplifier and active filter applications.
For engineers reviewing the TL074MDEP datasheet, TL074MDEP pinout, TL074MDEP application, or TL074MDEP equivalent, this page provides verified specifications, military-temperature SOIC-14 package details, JFET-input stage design implications, and validated alternative options for extended-temperature analog signal chains.
Technical Context
The TL074MDEP integrates four independent JFET-input op-amps on a single monolithic die, each featuring high-impedance (>10¹² Ω) inputs, internal frequency compensation, and bipolar output stages. Its architecture supports rail-to-rail common-mode input voltage range including VCC+, enabling operation with single-supply configurations when biased appropriately.
Designed for extended-life defense and aerospace use, the device implements latch-up-free processing, controlled baseline manufacturing, and full traceability per V62/11621-02XE-T specification. It maintains stable gain (AVD ≥ 15 V/mV) and CMRR ≥ 80 dB over its full –55°C to 125°C operating range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad JFET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL074MDREP | Same electrical specs and SOIC-14 package, but supplied in 2500-unit tape-and-reel vs. 50-unit tube | Better suited for automated SMT production; identical thermal and electrical behavior | Select TL074MDREP for high-volume board assembly; TL074MDEP preferred for prototyping and low-quantity qualification builds |
| OPA4134UA | Lower 8 nV/√Hz noise, higher 20 V/μs slew rate, but only rated for –40°C to +85°C and lacks MIL-qualified traceability | Optimized for commercial audio gear; not approved for defense/aerospace deployment | Choose OPA4134UA only for cost-sensitive, non-military applications where extended temperature range is unnecessary |
Compared with TL074MDREP, TL074MDEP offers identical performance in a tube-packaged form ideal for engineering validation; versus OPA4134UA, TL074MDEP trades minor noise/speed advantages for guaranteed –55°C operation, full V62 traceability, and defense-system compliance.

FAQ
What is the maximum operating temperature range for TL074MDEP?
The TL074MDEP is specified for continuous operation from –55°C to +125°C, meeting MIL-STD-883 Class B environmental requirements. This range is validated across all electrical parameters including input offset voltage, slew rate, and common-mode rejection ratio - no derating is required at temperature extremes. The device uses controlled-baseline fabrication and one-test-site validation to guarantee performance stability throughout this full span.
Does TL074MDEP support single-supply operation?
Yes, TL074MDEP supports single-supply operation when the input common-mode range is properly biased. Its common-mode input voltage extends to VCC+, allowing use with ground-referenced inputs if VCC− is tied to system ground and VCC+ is set to +15 V or less. However, output swing remains asymmetric (e.g., 0 V to +12 V), so level-shifting or rail-splitting networks may be needed for true rail-to-rail output in single-supply configurations.
How does TL074MDEP differ from commercial-grade TL074?
TL074MDEP differs from commercial TL074 in three key ways: it is manufactured under controlled baseline with single fab/test site, qualified for –55°C to +125°C (vs. 0°C to +70°C for standard grade), and shipped with full traceability per V62/11621-02XE-T. Electrical specs are identical, but TL074MDEP undergoes additional screening, extended burn-in, and lot-level documentation required for defense and aerospace deployments.
Is TL074MDEP pin-compatible with other quad op-amps in SOIC-14 packages?
TL074MDEP follows the industry-standard SOIC-14 pinout for quad op-amps (e.g., LM324, TL084), with matching channel assignments and supply pin locations. However, differences in input stage architecture (JFET vs. bipolar), slew rate, and noise performance mean functional substitution requires circuit-level verification - especially in high-frequency or low-noise designs where TL074MDEP's 13 V/μs slew rate and 18 nV/√Hz noise provide distinct advantages.
What decoupling is recommended for TL074MDEP power pins?
TI recommends placing a 0.1 µF X7R ceramic capacitor between VCC+ (Pin 11) and VCC− (Pin 4), located within 2 mm of the device, plus a bulk 10 µF tantalum or aluminum electrolytic capacitor nearby. This dual-tier approach suppresses both high-frequency switching noise and low-frequency supply sag. For multi-channel layouts, individual 0.1 µF caps per amplifier pair improve PSRR above 100 kHz and reduce inter-channel crosstalk.
