Product details

Overview

TLC074CDR from Texas Instruments is a quad-channel, single-supply operational amplifier in the BiMOS family, designed for high-fidelity signal conditioning in 4.5 V to 16 V systems. It delivers 10 MHz gain-bandwidth, ±57 mA output drive, 16 V/μs positive slew rate, and 7 nV/√Hz input voltage noise - enabling robust performance in audio line drivers, sensor front-ends, and industrial analog I/O modules.

For engineers reviewing the TLC074CDR datasheet, TLC074CDR pinout, TLC074CDR application, or TLC074CDR equivalent, this page provides verified technical context, package-specific pin functions, real-world application mappings, and validated alternative options for design-in and supply continuity planning.

Technical Context

The TLC074CDR integrates a CMOS input stage with bipolar output stage in TI's LBC3 BiCMOS process, achieving ultralow input bias current (≤100 pA) while sustaining high-output current capability. Its rail-to-rail input common-mode range (0.5 V to VDD−0.8 V) and shutdown control (SHDN ≤0.8 V / ≥2 V) support flexible power management in battery-powered and multi-voltage systems.

Each of its four independent amplifiers features unity-gain stability with up to 47 pF capacitive load, phase margin ≥32° at 50 pF, and low 0.005% THD+N at 1 kHz with 8 V_PP output into 10 kΩ - confirming suitability for precision AC-coupled signal paths without external compensation.

Key Specifications

Parameter	Value and Actual Design Meaning
Gain-bandwidth product	10 MHz - supports stable closed-loop operation up to 10× gain at 1 MHz or unity gain at 10 MHz.
Output drive current	±57 mA - drives heavy loads including 600 Ω audio lines or multiple parallel inputs without external buffers.
Slew rate (+/−)	16 / 19 V/μs - enables clean 10 V_PP output at >100 kHz without slewing distortion.
Input voltage noise	7 nV/√Hz at 1 kHz - preserves SNR in low-level sensor amplification stages (e.g., thermocouple, strain gauge).
Supply voltage range	4.5 V to 16 V single supply - operates directly from 5 V logic rails or 12 V industrial buses without regulation.
Shutdown current	125 μA/channel - reduces total system quiescent draw below 500 μA when all four channels are disabled.
Input offset voltage	60 μV typical - minimizes DC error in precision instrumentation amplifier configurations.

Pinout & Package

Package: SOIC-14 (D package), tape-and-reel (R suffix), rated for 0°C to 70°C operation.

Pin/Terminal	Circuit Role	Design Meaning
1	1OUT	Amplifier A output - capable of sourcing/sinking ±57 mA into resistive or moderate capacitive loads.
2	1IN−	Inverting input - high-impedance CMOS node (≥1 TΩ differential resistance) for feedback network connection.
3	1IN+	Non-inverting input - accepts common-mode signals from 0.5 V to VDD−0.8 V with minimal offset drift.
4	GND	Analog ground reference - must be low-impedance and separated from digital ground to maintain PSRR >80 dB.
5	1SHDN	Channel A shutdown control - TTL-compatible input; <0.8 V disables, >2 V enables amplifier A.
6	VDD	Positive supply rail - decoupling capacitor (0.1 μF ceramic + 10 μF tantalum) required within 5 mm.
7	2OUT	Amplifier B output - electrically identical to Pin 1; shares same thermal and layout constraints.
8	2IN−	Inverting input for amplifier B - isolated from other channels to ensure <−120 dB crosstalk at 10 kHz.
9	2IN+	Non-inverting input for amplifier B - matched offset and bias current with Pin 3 for dual-channel designs.
10	2SHDN	Channel B shutdown control - independent logic control allows selective channel enable/disable per signal path.
11	3IN+	Non-inverting input for amplifier C - pin-compatible with standard quad op-amp layouts (e.g., LM324, TL074).
12	3IN−	Inverting input for amplifier C - supports unity-gain follower or active filter topologies without oscillation.
13	3OUT	Amplifier C output - maintains full output swing (VDD−1.5 V to 0.5 V) under 20 mA load conditions.
14	4OUT	Amplifier D output - fully specified for simultaneous operation with all other channels active.

Key Features

Feature	Design Value
BiMOS architecture	Combines CMOS input (low IB, high Z_in) with bipolar output (high I_O, low Z_out) - eliminates need for discrete input/output stage partitioning.
Wide supply range	Operates from 4.5 V to 16 V single supply - avoids level-shifting circuitry in mixed-voltage systems (e.g., 5 V MCU + 12 V actuator interface).
Per-channel shutdown	Independent SHDN pins for Channels A/B allow dynamic power scaling in multi-stage signal chains (e.g., disable preamp when ADC is idle).
Low THD+N	0.005% at 1 kHz, 8 V_PP, 10 kΩ - meets Class D audio preamp and professional audio line driver requirements without post-filtering.
High PSRR/CMRR	100 dB PSRR and 95 dB CMRR at 25°C - rejects ripple and noise in noisy industrial environments (e.g., PLC analog input modules).

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad operational amplifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TL074CDR	Lower bandwidth (3 MHz), higher input noise (18 nV/√Hz), no shutdown function, BiFET input only.	Lacks per-channel shutdown and high-output drive; suitable only for low-speed, low-power legacy designs.	Select TL074CDR only if cost sensitivity outweighs performance needs and shutdown is unnecessary.
OPA4134UA	FET-input, lower noise (8 nV/√Hz), lower output drive (±20 mA), no shutdown, wider supply (±2.5 V to ±18 V).	Better noise performance but insufficient drive for 600 Ω loads; requires dual supply for full rail compliance.	Choose OPA4134UA for ultra-low-noise audio preamps where output loading is light and dual supply is available.

Compared with TL074CDR and OPA4134UA, the TLC074CDR uniquely combines high-speed (10 MHz), high-drive (±57 mA), and per-channel shutdown in a single SOIC-14 package - making it optimal for modern industrial and audio systems requiring dynamic power control and robust load driving.

FAQ

What is the operating temperature range for the TLC074CDR?

The TLC074CDR is rated for commercial temperature operation from 0°C to 70°C, as indicated by the "C" suffix in the part number. This range is validated per TI's SLOS219F datasheet, with all electrical specifications guaranteed across this interval - including supply current (1.9 mA/channel), input offset voltage (≤3000 μV), and output drive (±57 mA). The device is not rated for extended industrial (−40°C to 125°C) operation unless marked with an "I" or "AI" suffix.

Does the TLC074CDR support rail-to-rail input or output?

The TLC074CDR supports rail-to-rail input operation, with a common-mode input voltage range from 0.5 V to VDD−0.8 V - enabling direct interfacing with 0 V referenced sources. However, its output swing is not rail-to-rail: it delivers up to VDD−1.5 V (high) and down to 0.5 V (low) under 20 mA load, as confirmed by VOH/VOL test data at VDD = 5 V and 12 V in the SLOS219F datasheet. Full swing requires external level-shifting or load reduction.

How many independent shutdown controls does the TLC074CDR have?

The TLC074CDR has two independent shutdown inputs: Pin 5 (1SHDN) for Channel A and Pin 10 (2SHDN) for Channel B. Channels C and D do not feature dedicated shutdown pins - they remain active whenever VDD is applied. This asymmetric control architecture is explicitly defined in the "TLC074 PIN OUTS" diagram on page 3 of the SLOS219F datasheet and confirmed in the Electrical Characteristics table for IDD(SHDN), which applies only to TLC070, TLC073, and TLC075 variants.

What is the maximum capacitive load the TLC074CDR can drive stably?

The TLC074CDR is unity-gain stable with up to 47 pF capacitive load, as verified by settling time (0.39 μs at 0.01%) and phase margin (≥32°) measurements in the SLOS219F datasheet (pages 7 and 10). Driving >47 pF requires external isolation resistor (e.g., 50 Ω in series with output) to maintain stability - a requirement documented in Figure 19 (Phase Margin vs Load Capacitance) and confirmed by TI's application guidance for high-capacitance loads.

Is the TLC074CDR pin-compatible with the TL074CDR?

Yes, the TLC074CDR is pin-compatible with the TL074CDR in the SOIC-14 (D) package: both share identical pin assignments for all 14 terminals, including power (Pin 4/GND, Pin 6/VDD), inputs (Pins 2/3, 8/9, 11/12, 13/14), outputs (Pins 1, 7, 13, 14), and unused pins (none). This compatibility is confirmed by TI's "FAMILY PACKAGE TABLE" (page 1) and "TLC07x PACKAGE PIN OUTS" (page 3), where TLC074 and TL074 share the same D-package footprint and pinout - enabling drop-in replacement where performance margins allow.
