Product details
Overview
TLC5916INE4 from Texas Instruments is an 8-channel constant-current LED sink driver IC designed for precise current control in LED display and lighting systems. It delivers 3–120 mA per channel with ±3% inter-channel current accuracy, supports 3.0–5.5 V supply, and features open-load and overtemperature detection. It operates in cascaded configurations for large-scale LED arrays such as video billboards and scrolling displays.
For engineers reviewing the TLC5916INE4 datasheet, TLC5916INE4 pinout, TLC5916INE4 application, or TLC5916INE4 equivalent, key selection criteria include its 30-MHz serial clock capability, single-REXT-based current programming, error-detection mode via OE/LE dual-function pins, and compatibility with 16-pin PDIP packaging for through-hole industrial designs.
Technical Context
The TLC5916INE4 integrates an 8-bit shift register, output latches, and eight independent constant-current sinks with thermal shutdown and open-load fault detection. Its dual-mode operation-Normal Mode for data shifting/latching and Special Mode for error status readback or global current gain adjustment-relies on pulse-triggered transitions on OE(ED2) and level-sensitive decoding on LE(ED1).
All outputs share a single external REXT resistor to set nominal current, while 256-step programmable global gain (1/12 to 127/128) enables fine-tuning across devices for white-balancing. Unlike the TLC5917, the TLC5916INE4 omits short-to-VLED detection but retains open-load and overtemperature monitoring per channel.
Key Specifications

Pinout & Package
Package: PDIP-16 (19.30 mm × 6.35 mm), through-hole mounting compatible with legacy industrial PCB assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Ground reference | Common return for logic and sink current paths; must be low-impedance |
| SDI (Pin 2) | Serial data input | Accepts 3.3-V/5-V CMOS-level data for shift register loading |
| CLK (Pin 3) | Clock input | Rising-edge triggered; controls data shift into 8-bit shift register |
| LE(ED1) (Pin 4) | Latch enable / Error detect mode select | High→low transition latches shift register to output latch; level determines Special Mode function |
| OUT0–OUT7 (Pins 5–12) | Constant-current sink outputs | Each drives LED cathode to GND; current set by REXT and gain code |
| VDD (Pin 16) | Power supply | 3.0–5.5 V input powering logic and internal regulators |
| R-EXT (Pin 15) | Current-setting resistor terminal | Connects external resistor to GND to define full-scale output current |
| SDO (Pin 14) | Serial data output | Shifts out latched data or error status bits; enables daisy-chaining |
| OE(ED2) (Pin 13) | Output enable / Error detect trigger | Active-low enables outputs; one-clock pulse initiates Special Mode entry |
Key Features
| Feature | Design Value |
|---|---|
| Single-resistor current programming | One REXT sets identical baseline current across all 8 channels - simplifies BOM and layout |
| 256-step global current gain | Runtime-adjustable gain (1/12 to 127/128) compensates inter-IC current variation for color-matching |
| Per-channel open-load detection | Detects open LED string per output when enabled - prevents false brightness or thermal runaway |
| Channel-specific overtemperature shutdown | Individual thermal cutoff per OUTx avoids full-array blanking during localized overheating |
| Schmitt-trigger inputs | CLK, LE(ED1), OE(ED2), and SDI tolerate slow-rising signals and noise - improves system robustness |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LED sink driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC5916IDR | Same functionality and electrical specs; SOIC-16 surface-mount package instead of PDIP-16 | Requires PCB redesign for SMT assembly; better thermal performance in dense layouts | Select for automated manufacturing or space-constrained boards where through-hole is impractical |
| TLC59282DBQR | 16-channel version with identical architecture, same REXT programming, and added short-circuit detection | Supports higher channel density per IC; includes short-to-VLED fault detection missing in TLC5916INE4 | Select when expanding channel count or requiring full fault coverage including short-circuit conditions |
Compared with TLC5916INE4, the TLC5916IDR offers identical drive capability in a smaller SOIC package ideal for modern SMT lines, while the TLC59282DBQR doubles channel count and adds short-circuit detection - making it suitable for next-generation LED systems demanding higher integration and broader fault coverage.

FAQ
What is the maximum output voltage rating for the TLC5916INE4?
The TLC5916INE4 supports up to 20 V at its OUT0–OUT7 pins. This allows direct driving of LED strings with combined forward voltages up to 20 V - sufficient for 5–6 white LEDs in series or high-VF specialty LEDs. Exceeding this voltage risks permanent damage to the output transistors, as specified in the Absolute Maximum Ratings table of the SLVS695D datasheet.
Does the TLC5916INE4 support short-circuit detection like the TLC5917?
No, the TLC5916INE4 does not support short-to-VLED detection. Per the Device Comparison Table in the SLVS695D datasheet, only the TLC5917 includes short-load detection; the TLC5916INE4 implements open-load and overtemperature detection only. This distinction is hardware-defined and cannot be enabled via configuration.
How is output current programmed on the TLC5916INE4?
Output current on the TLC5916INE4 is set using a single external resistor (REXT) connected between Pin 15 (R-EXT) and GND. The nominal current per channel equals 12.5 V / REXT, yielding 3–120 mA for REXT values from ~104 kΩ down to ~104 Ω. A 256-step global gain register further scales this base current in firmware.
Can multiple TLC5916INE4 ICs be cascaded, and what is the maximum clock frequency?
Yes, TLC5916INE4 ICs support daisy-chain configuration via SDI-to-SDO interconnection. The maximum guaranteed clock frequency is 30 MHz under cascade operation, as confirmed in Section 7.7 and 7.8 of the SLVS695D datasheet. Signal integrity at this rate requires controlled trace length and proper termination in high-density layouts.
What package type is used for the TLC5916INE4, and is it RoHS-compliant?
The TLC5916INE4 uses a 16-pin plastic dual in-line package (PDIP) with body dimensions 19.30 mm × 6.35 mm. It is RoHS-compliant and lead-free, meeting TI's standard environmental specifications per the SLVS695D datasheet orderable addendum and TI's official product folder.
