Product details
Overview
TLC59211IN from Texas Instruments is an 8-bit DMOS sink current driver IC designed for LED and solenoid load control in 5-V systems. It delivers up to 200 mA per channel at 30 V output voltage, features latch-up immunity >250 mA, and operates across –40°C to 85°C. Used in LED matrix displays and relay drivers where high-voltage sinking with discrete logic-level control is required.
For engineers reviewing the TLC59211IN datasheet, TLC59211IN pinout, TLC59211IN application, or TLC59211IN equivalent, key selection criteria include per-channel 200 mA sink capability, 30 V VDS rating, PDIP-20 package thermal performance (RθJA = 54.4°C/W), and compatibility with 3.3–5.5 V logic interfaces.
Technical Context
The TLC59211IN implements eight independent DMOS N-channel sink switches, each controlled directly by a parallel input (D1–D8). No internal shift register or latching logic is present - inputs drive outputs synchronously with no propagation delay stacking.
Each output includes a parasitic clamp diode to handle inductive kickback from solenoids or relay coils. The device uses TI's DMOS process for robustness against overvoltage transients and ESD, with HBM rating of ±2000 V and CDM rating of ±100 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS Max | 30 V - supports direct connection to 24-V LED strings or solenoid supplies without external flyback protection |
| IDS Max per Channel | 200 mA - enables driving high-brightness LEDs or small relays without external buffers |
| VCC Range | 3.0–5.5 V - compatible with both 3.3-V and 5-V microcontroller I/O domains |
| rON (Typ) | 2 Ω @ 4.5 V - ensures <0.7 V dropout at 200 mA, minimizing power loss and heat generation |
| Operating Temp | –40°C to +85°C - qualified for industrial and automotive under-hood ambient environments |
| RθJA | 54.4°C/W (PDIP) - defines maximum power dissipation limit (~0.7 W) before thermal shutdown in still air |
| ESD HBM | ±2000 V - meets JEDEC JESD22-A114A, enabling handling without special ESD precautions beyond standard protocols |
Pinout & Package
Package: PDIP-20 (N), body size 24.33 mm × 6.35 mm, through-hole mount, RoHS-compliant NiPdAu lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 10 | No Connection (N.C.) | Internally unconnected; must be left floating or tied to GND - no routing or loading required |
| 2–9 (D1–D8) | Digital Input | Direct parallel control lines; logic high enables corresponding sink output; CMOS-compatible thresholds |
| 11 | GND | Power ground reference for all sinks and logic; requires low-impedance PCB plane connection |
| 12–19 (Y1–Y8) | Sink Output | Drains current from connected loads (LED cathodes, relay coils); each rated for 200 mA continuous |
| 20 | VCC | Logic and gate drive supply; decoupling capacitor (0.1 µF ceramic) required within 5 mm of pin |
Key Features
| Feature | Design Value |
|---|---|
| DMOS Process Technology | Enables 30 V output voltage tolerance and inherent latch-up immunity exceeding 250 mA per JEDEC JESD17 |
| Integrated Clamp Diode | Parasitic body diode on each output provides flyback path for inductive loads - eliminates need for external diodes |
| High Sink Current Density | 200 mA per channel in PDIP package allows compact LED array or multi-relay control without external FETs |
| Wide Supply Range | 3.0–5.5 V operation supports mixed-voltage systems and brown-out resilience down to 3 V |
| Industrial Temperature Range | –40°C to +85°C qualification ensures stable timing and conduction characteristics in uncontrolled environments |
Applications
| LED Matrix Display Driver | Industrial Relay Interface |
|---|---|
|
Use Scenario: Driving 8-segment alphanumeric displays or 8×8 LED dot-matrix panels using common-anode configuration. IC Role / Device Role / Timing Role: Sinks cathode current from LEDs; accepts static parallel data from MCU GPIO or shift register output. Use Value: Eliminates need for 8 discrete NPN transistors or MOSFETs; reduces BOM count and PCB area while maintaining full 200 mA per segment. |
Use Scenario: Controlling eight 24-VDC industrial relays in PLC I/O modules or machine control cabinets. IC Role / Device Role / Timing Role: Provides isolated, high-voltage sinking interface between 3.3/5-V logic and relay coils. Use Value: Built-in clamp diodes suppress inductive kickback, preventing MCU reset or logic corruption without external snubbers. |
| Automotive Interior Lighting | Test Equipment Load Switching |
|
Use Scenario: Dimmable map light or courtesy light control in automotive cabins with PWM brightness adjustment. IC Role / Device Role / Timing Role: Sinks LED string current; duty cycle modulated via D-input toggling synchronized to vehicle bus clock. Use Value: 30 V VDS rating accommodates battery transients up to 28 V; thermal design supports sustained 130 mA per channel at 100% duty cycle. |
Use Scenario: Automated test fixture that cycles multiple DUT power rails or signal paths using programmable switching. IC Role / Device Role / Timing Role: Acts as eight independently controllable high-side-off / low-side-on switches for load activation. Use Value: Parallel input architecture enables deterministic, zero-latency switching - critical for repeatability in production test sequences. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit sink driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ULN2803A | Bipolar Darlington output; higher VCE(sat) (~1.3 V), lower max current (500 mA total, not per channel) | Higher power dissipation at 200 mA; requires external flyback diodes for inductive loads | Choose when legacy bipolar design exists and lower cost outweighs efficiency loss |
| TLC5916IDR | Constant-current LED driver with internal current regulation; IOUT adjustable via resistor (max 120 mA) | No voltage tolerance beyond VCC; not suitable for 24-V solenoid or relay loads | Prefer when precise LED brightness uniformity is required over high-voltage flexibility |
Compared with ULN2803A and TLC5916IDR, the TLC59211IN uniquely combines per-channel 200 mA sinking, 30 V output voltage tolerance, integrated clamp diodes, and DMOS robustness - making it optimal for mixed-load (LED + relay) industrial control where reliability and voltage headroom are critical.

FAQ
What is the maximum continuous current per channel for TLC59211IN at 85°C ambient?
The TLC59211IN supports 130 mA per channel continuously at 85°C ambient when all eight outputs are active in the PDIP package, as defined by its thermal derating curve and RθJA = 54.4°C/W. This value drops to 200 mA only at lower duty cycles or reduced channel count - full 200 mA is specified at 25°C with ≤24% duty cycle. Always verify junction temperature using PDISS = I² × rON + I × VOL.
Does TLC59211IN include internal ESD protection, and what standards does it meet?
Yes, the TLC59211IN integrates on-chip ESD protection meeting JEDEC standards: ±2000 V Human Body Model (HBM), ±200 V Machine Model (MM), and ±1000 V Charged Device Model (CDM). These ratings are verified per JESD22-A114, JESD22-A115, and JESD22-C101, enabling safe handling in standard manufacturing environments without additional protection circuitry.
Can TLC59211IN drive 24-V LED strings directly, and what is the voltage limit at the Yx pins?
Yes, the TLC59211IN can drive 24-V LED strings directly. Its absolute maximum VDS rating is 32 V, and recommended operating VDS is 30 V - sufficient to accommodate 24-V nominal supplies plus automotive load-dump transients. The Yx pins tolerate up to 30 V when OFF, allowing common-anode LED configurations with VLED supplied externally.
Is there a built-in shift register or latching function in TLC59211IN?
No, the TLC59211IN has no internal shift register or storage latch. It is a direct-logic sink driver: D1–D8 inputs control Y1–Y8 outputs synchronously with no internal clock or data retention. For serial-to-parallel conversion, an external shift register such as SN74LV595A must be used upstream - as referenced in TI's typical application diagrams.
What package options are available for TLC59211IN, and is the TSSOP variant pin-compatible?
The TLC59211IN is specified for PDIP-20 (N package) only. The TSSOP-20 variant is the TLC59211IPWR - same pinout and function but different thermal and packaging characteristics (RθJA = 94.3°C/W, tape-and-reel packaging). Both share identical pin numbering and electrical behavior, enabling drop-in replacement in layout if thermal design accommodates the higher junction rise.
