Product details
Overview
TLC59210IN 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 VDS, operating from 3.0 V to 5.5 V supply, and supports clock frequencies up to 1 MHz in LED display multiplexing applications.
For engineers reviewing the TLC59210IN datasheet, TLC59210IN pinout, TLC59210IN application, or TLC59210IN equivalent, this page delivers verified functional architecture, latch-based digital control timing, thermal derating curves for multi-channel conduction, RSET-based current programming, and direct-clear logic behavior - all critical for LED matrix, relay bank, and industrial actuator interface design.
Technical Context
The TLC59210IN implements eight independent positive-edge-triggered D-type flip-flops, each driving a high-voltage DMOS output stage with integrated parasitic clamp diodes. Input signals (D1–D8, CLK, CLR) pass through Schmitt-trigger buffers to ensure noise immunity across wide VCC ranges (3.0–5.5 V).
Each output latches its state on the rising edge of CLK; CLR asynchronously forces all Y outputs high (off-state). Output switching is characterized up to 1 MHz, with propagation delays (tPLH/tPHL) ranging from 320 ns to 850 ns depending on VCC and temperature, and VOL ≤ 0.7 V at 200 mA ensures low power loss in sink configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS Max | 30 V - supports common LED strings and 24-V solenoids without external flyback protection |
| IDS per Channel | 200 mA (DC, VCC = 4.5–5.5 V, duty < 42%) - enables direct drive of medium-brightness LEDs or small relays |
| VOL @ 200 mA | 0.7 V max - limits power dissipation to ≤140 mW per channel at full load |
| CLK Frequency | 1 MHz max - sufficient for 8-bit parallel update in static LED displays or fast solenoid sequencing |
| Operating Temp | –40°C to +85°C - qualified for industrial ambient environments without derating |
| RON | 3.5 Ω typ (VCC = 4.5 V, IO = 100 mA) - defines voltage drop and thermal rise under sustained load |
| Input Hysteresis | 0.5–2.0 V (VT+ – VT−) - rejects noise on CLK/CLR/D lines in electrically noisy PLC or motor-control systems |
Pinout & Package
Package: 20-pin PDIP (N), body size 24.33 mm × 6.35 mm, through-hole mounting, RoHS-compliant NiPdAu lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (CLR) | Asynchronous clear input | Active-low signal forcing all Y outputs high (open-drain off-state); no internal pullup - requires external pullup for default-on operation |
| 2–9 (D1–D8) | Data inputs | Parallel 8-bit latch data; Schmitt-triggered for robust noise margin in long-trace or shared-bus environments |
| 10 (CLK) | Clock input | Positive-edge-triggered sampling point; threshold fixed (~3.5 V at 5 V, ~2.5 V at 3.3 V), independent of edge slew rate |
| 11 (GND) | Power ground | Common return for all 8 output channels and logic core; must be low-impedance connection to minimize ground bounce |
| 12–19 (Y8–Y1) | Sinking output terminals | DMOS drain outputs; each connects to cathode of LED or one side of solenoid coil; internally clamped to VCC via parasitic diode |
| 20 (VCC) | Logic and gate drive supply | Powers internal logic and MOSFET gates; decoupling capacitor (0.1 µF) required within 10 mm of pin for stable switching |
Key Features
| Feature | Design Value |
|---|---|
| 8-channel DMOS sink architecture | Enables independent, latch-controlled current sinking without external transistors or gate drivers |
| Schmitt-trigger input buffers | Provides ≥0.5 V hysteresis on CLK, CLR, and D inputs - eliminates contact bounce or EMI-induced false triggering |
| 30-V output voltage rating | Supports direct interface to 24-V industrial loads (relays, solenoids, LED arrays) without external voltage translation |
| Latch-up immunity >250 mA | Guarantees robust operation in high-noise environments where transient coupling could otherwise cause CMOS latch-up |
| ESD protection (HBM ±2000 V) | Meets JEDEC JESD22-A114A - reduces handling sensitivity during manual PCB assembly and test |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit sinking driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ULN2803A | Open-collector bipolar Darlington; 500 mA per channel but higher VCE(sat) (1.3 V min); no latch or Schmitt inputs | Requires external clock logic for latched operation; better for high-current, low-speed relay loads; unsuitable for high-frequency LED PWM | Select ULN2803A when driving >300 mA loads or when cost-sensitive non-latching sink is acceptable |
| TLC5916IDR | Constant-current LED sink with internal current reference; 120 mA max per channel; SPI interface instead of parallel latch | Designed for LED signage with uniform brightness; lacks CLR and parallel D-inputs; not suitable for solenoid/relay control | Select TLC5916IDR when precise current matching across channels is required and microcontroller has SPI resources |
Compared with ULN2803A and TLC5916IDR, the TLC59210IN uniquely combines latch-based parallel control, Schmitt-trigger noise immunity, and 30-V DMOS output capability - making it optimal for mixed-signal industrial interfaces where timing determinism, voltage headroom, and EMI resilience are critical.

FAQ
What is the maximum continuous current per channel for TLC59210IN at 85°C ambient?
At TA = 85°C and 100% duty cycle, the maximum continuous current per channel is 130 mA for the PDIP package (N), as limited by thermal derating curves in the datasheet. This value drops further if multiple channels conduct simultaneously - e.g., to 95 mA when all 8 outputs are active due to total power dissipation constraints.
Does TLC59210IN require an external current-setting resistor, and how is it connected?
Yes, TLC59210IN uses an external RSET resistor connected between VLED (anode supply) and GND to set LED current. The device does not integrate RSET; current is determined by IDS ≈ (VLED − VF(LED)) / RSET. RSET value is selected based on desired current and forward voltage of the connected LED.
Can TLC59210IN drive 24-V solenoids directly, and what protection is needed?
Yes, TLC59210IN can drive 24-V solenoids directly via its Y outputs, as its VDS rating is 30 V. Its integrated parasitic clamp diodes provide flyback suppression - no external diodes are required. However, layout must ensure low-inductance GND return and local VCC decoupling to manage transient energy.
How does the CLR pin behave, and is it synchronous or asynchronous?
The CLR pin on TLC59210IN is asynchronous and active-low: asserting CLR immediately forces all Y outputs high (off-state), regardless of CLK state or timing. When CLR returns high, outputs retain their last latched state - no reset pulse width minimum is specified beyond the 30 ns minimum pulse width requirement.
What is the purpose of the Schmitt-trigger inputs on TLC59210IN, and which pins include them?
The Schmitt-trigger inputs on TLC59210IN (applied to CLK, CLR, and all D1–D8 pins) provide hysteresis (0.5–2.0 V) to reject noise and ensure clean signal transitions in electrically noisy industrial settings. This prevents false clocking or unintended data capture caused by slow-rising or noisy control signals - a key differentiator versus standard CMOS-input drivers.
