Product details
Overview
TLC59210IPWR from Texas Instruments is an 8-bit DMOS sink driver IC with Schmitt-trigger inputs, designed for LED and solenoid load control. It features 8 independent sinking outputs (Y1–Y8), each capable of 200 mA continuous current at up to 30 V output voltage, operating from 3.3 V or 5 V logic supply. Used in LED display matrix drivers where precise parallel bit-pattern latching and high-voltage current sinking are required.
For engineers reviewing the TLC59210IPWR datasheet, TLC59210IPWR pinout, TLC59210IPWR application, or TLC59210IPWR equivalent, key selection criteria include its 200 mA per-channel sink capability, 30 V output voltage rating, positive-edge D-type latch architecture with dedicated CLR input, TSSOP-20 package thermal performance, and compatibility with microcontroller parallel bus interfaces driving LED arrays or electromechanical loads.
Technical Context
The TLC59210IPWR implements eight independent D-type flip-flops, each with Schmitt-trigger buffered data inputs (D1–D8) and a shared positive-edge clock (CLK) and direct clear (CLR). Output states are latched synchronously on CLK rising edges, decoupling timing from input transition speed via voltage-level-triggered clock detection.
Each Y-output is a DMOS transistor with integrated parasitic clamp diodes, supporting sink operation into loads referenced to VLED (up to 30 V), while the logic core operates from VCC = 3 V to 5.5 V. Thermal derating curves confirm maximum per-channel current depends on simultaneous active outputs, duty cycle, and ambient temperature - critical for sustained LED brightness control without thermal shutdown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Type | 8-channel DMOS sink driver with latch; each channel independently controlled by D-input and CLK edge |
| Max Output Current | 200 mA per channel (VCC = 4.5–5.5 V, duty cycle < 42%); derated at higher duty cycles or multiple active channels |
| Output Voltage Rating | 30 V drain-to-source (Vds); supports LED strings or solenoids powered up to 30 V referenced to Y pins |
| Logic Supply Range | 3.0 V to 5.5 V VCC; compatible with both 3.3 V and 5 V microcontrollers without level shifting |
| Input Thresholds | Schmitt-trigger inputs: VT+ = 3.5 V (5 V mode), VT− = 1.5 V; hysteresis = 0.5–2 V prevents noise-induced toggling |
| Timing Performance | Min CLK pulse width = 30 ns; setup/hold = 10 ns; propagation delays tPLH/tPHL ≤ 550 ns (VCC = 4.5–5.5 V, CL = 30 pF) |
| Operating Temp | –40°C to +85°C; specified across full range with thermal derating curves for power dissipation |
Pinout & Package
TLC59210IPWR uses a 20-pin TSSOP (PW) package, 6.50 mm × 4.40 mm body size, 1.2 mm max height, with exposed pad not electrically connected. Pin 1 index located at top-left corner (Q1 quadrant), lead finish NIPDAU, MSL Level-1 (unlimited reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (CLR) | Active-low asynchronous reset | Forces all Y outputs high (OFF) regardless of CLK or D state; essential for system initialization or fault recovery |
| 2–9 (D1–D8) | Parallel data inputs | Hold latch input states; Schmitt-triggered for noise immunity on microcontroller GPIO lines |
| 10 (CLK) | Positive-edge clock | Transfers D1–D8 values to Y1–Y8 outputs synchronously; voltage-level triggered, not edge-rate dependent |
| 11 (GND) | Power ground reference | Common return for logic supply and output sink current; requires low-impedance PCB connection to minimize VOL rise |
| 12–19 (Y8–Y1) | Sink output terminals | DMOS drains; connect to cathodes of LEDs or one side of solenoids; source tied internally to GND |
| 20 (VCC) | Logic supply input | Powers internal flip-flops and buffers; bypass capacitor required near pin for stable operation |
Key Features
| Feature | Design Value |
|---|---|
| 8-bit parallel latch architecture | Enables synchronous update of all 8 outputs with single CLK edge - eliminates partial-state glitches during pattern changes |
| 30 V output voltage tolerance | Supports direct drive of high-VF LED strings or 24 V solenoids without external transistors or boost circuitry |
| Integrated Schmitt-trigger inputs | Rejects <1.5 V noise on D/CLK/CLR lines - critical for reliable operation in electrically noisy industrial environments |
| Thermally robust DMOS process | Guarantees 200 mA per channel at 85°C ambient when ≤4 outputs active at ≤42% duty cycle - validated by TI's derating curves |
| Direct clear (CLR) function | Hardware-level emergency OFF for all outputs - enables fail-safe behavior in safety-critical lamp or relay control systems |

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 |
|---|---|---|---|
| TLC59282IPWPR | 16-channel sink driver, same TSSOP-20 package, 120 mA/channel, integrated PWM dimming control | Requires external PWM signal generation; better suited for brightness-controlled LED signage vs. static pattern control | Select when needing more channels or analog dimming; not drop-in due to different pinout and control protocol |
| TPIC6B595N | 8-bit shift-register sink driver (serial-in/parallel-out), PDIP-16, 150 mA/channel, open-drain outputs | Serial interface reduces MCU GPIO count but adds timing overhead; lacks synchronous latch and CLR | Choose for space-constrained designs with limited parallel pins; accept trade-off in update latency and lack of hardware reset |
Compared with TLC59210IPWR, TLC59282IPWPR offers double the channel count and built-in PWM but requires serial configuration and has lower per-channel current. TPIC6B595N reduces pin count via SPI interface but sacrifices synchronous update and failsafe CLR - making TLC59210IPWR optimal for deterministic parallel-control systems.

FAQ
What is the maximum continuous current per channel for TLC59210IPWR?
The TLC59210IPWR supports up to 200 mA per channel when VCC = 4.5 V to 5.5 V and duty cycle is below 42%. At 100% duty cycle, the rated current drops to 130 mA for the TSSOP-20 package due to thermal limits. Derating curves in the datasheet (Figure 9) define exact limits based on ambient temperature and number of simultaneously active channels - critical for thermal design validation of the TLC59210IPWR.
Does TLC59210IPWR require external pull-up resistors on its Y outputs?
No, the TLC59210IPWR Y outputs are open-drain DMOS sinks - they do not require external pull-ups. Loads (e.g., LED anodes or solenoid high-side supplies) must be connected to a positive voltage rail (up to 30 V), with current returning through the Y pin to GND. Pull-ups would conflict with sink operation and are neither used nor recommended in any TLC59210IPWR application circuit.
Can TLC59210IPWR operate with a 3.3 V microcontroller while driving 24 V LEDs?
Yes. The TLC59210IPWR accepts 3.3 V logic levels on D, CLK, and CLR inputs (VIH min = 2.52 V at VCC = 3.3 V), while its Y outputs can sink current from loads up to 30 V. This allows direct interface between a 3.3 V MCU and 24 V LED strings without level shifters - a key design advantage confirmed in the TLC59210IPWR recommended operating conditions table.
What is the purpose of the RSET pin on TLC59210IPWR?
The TLC59210IPWR does not have an RSET pin. That functionality exists in TI's TLC59xx constant-current LED drivers (e.g., TLC5940), but the TLC59210IPWR is a voltage-controlled sink driver - LED current is set externally by the series resistor between VLED and the LED anode. The datasheet clarifies this in Section 9.1.1: "The LED current is primarily dependent on the supply voltage, the forward voltage of the LED, and the series resistor (RSET)." So RSET is a board-level component, not a pin on the TLC59210IPWR.
Is TLC59210IPWR pin-compatible with the PDIP version TLC59210IN?
Yes, the TLC59210IPWR (TSSOP-20) and TLC59210IN (PDIP-20) share identical pin numbering, pin functions, and electrical specifications. Both follow the same 20-pin layout: CLR, D1–D8, CLK, GND, Y8–Y1, VCC. Mechanical dimensions differ, but PCB footprint design rules (e.g., land patterns, stencil apertures) are distinct - migration requires layout revision, though schematic connectivity remains unchanged for the TLC59210IPWR and TLC59210IN.
