Product details
Overview
TLP2166A(TP,F) from Toshiba Electronic Devices & Storage Corporation is a dual-channel, high-speed photovoltaic coupler with totem-pole logic outputs, designed for isolated digital signal transmission in 3.3-V systems. It integrates two independent IRED–photodetector pairs in one SO8 package, delivers 15 MBd NRZ data rate, achieves ≤75 ns propagation delay, and sustains operation across –40°C to +100°C - enabling use in plasma display panel (PDP) scan drivers and industrial high-speed serial interfaces.
For engineers reviewing the TLP2166A(TP,F) datasheet, TLP2166A(TP,F) pinout, TLP2166A(TP,F) application, or TLP2166A(TP,F) equivalent, key selection criteria include guaranteed 3.3-V supply compatibility, ±15 kV/μs common-mode transient immunity, dual-channel isolation with independent anode/cathode terminals, and UL/cUL/VDE safety certifications supporting reinforced insulation in safety-critical control loops.
Technical Context
The TLP2166A(TP,F) implements two fully independent optically isolated channels, each combining a GaAs infrared LED with a monolithic high-gain photodetector IC featuring totem-pole output stage. Its logic inversion behavior (LED ON → output LOW) and strict 3.0–3.6 V VCC range are fixed by internal detector biasing and threshold design.
Isolation performance relies on internal shielded die construction and molded SO8 package geometry, delivering 2500 Vrms withstand voltage and <0.8 pF input-to-output capacitance. Common-mode transient immunity is achieved via differential sensing and internal shielding between input and output sections, validated at ±15 kV/μs under defined test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0–3.6 V - mandates external 3.3-V rail; operation below 3.0 V risks unstable output or elevated ICCH. |
| Max Switching Speed | 15 MBd (NRZ, typ.) - supports high-frequency serial protocols such as RS-422/485 isolators or PDP address drivers. |
| Propagation Delay | ≤75 ns (tpHL/tpLH) - enables sub-100 ns digital edge transmission across isolation barrier for real-time control. |
| Input Threshold Current | IFHL ≤ 3 mA - ensures reliable logic LOW detection with low-drive microcontrollers or FPGA I/Os. |
| Common-Mode Immunity | ±15 kV/μs - suppresses fast transients from motor drives or power converters without output corruption. |
| Isolation Voltage | 2500 Vrms - meets reinforced insulation requirements per UL 1577 and EN 60747-5-5 (with V4 option). |
| Operating Temperature | –40°C to +100°C - qualified for industrial motor control, HVAC, and PDP subsystems without derating. |
Pinout & Package
The TLP2166A(TP,F) is housed in an 8-pin Small Outline (SO8) package per JEDEC MS-012, with 1.27 mm pitch, 5.0 mm body width, and 0.11 g typical mass. A 0.1 μF ceramic bypass capacitor must be placed between pins 8 (VCC) and 5 (GND), with total lead length ≤1 cm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: ANODE 1 | LED Channel 1 anode | Connects to 3.3-V source via current-limiting resistor; forward voltage ~1.65 V @ 10 mA. |
| 2: CATHODE 1 | LED Channel 1 cathode | Drives logic HIGH when LED is OFF; reverse voltage rating 5 V limits pull-up configuration. |
| 3: CATHODE 2 | LED Channel 2 cathode | Independent second channel input; shares no electrical connection with Channel 1 LED path. |
| 4: ANODE 2 | LED Channel 2 anode | Enables dual isolated inputs without shared current paths - critical for cross-talk–sensitive applications. |
| 5: GND | Detector ground reference | Common return for both output stages; must be tied to system logic ground, not power ground. |
| 6: VO2 (Output 2) | Channel 2 totem-pole output | Active LOW logic output; VOL ≤ 0.6 V @ 1.6 mA sink load; VOH ≥ 2.0 V @ –0.02 mA source. |
| 7: VO1 (Output 1) | Channel 1 totem-pole output | Electrically isolated from VO2; supports independent enable/control signals in multi-axis systems. |
| 8: VCC | Detector supply input | Must be decoupled to Pin 5; supplies both photodetector ICs; max 6 V absolute rating. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel integration | Two independent opto-isolators in single SO8 package - reduces PCB area by ~40% vs. discrete solutions. |
| Inverting totem-pole output | No external pull-up required; drives CMOS/TTL loads directly with 10 mA sink/source capability. |
| High CMTI | ±15 kV/μs immunity - maintains signal integrity in noisy environments like servo drive feedback loops. |
| Low inter-channel capacitance | <0.8 pF input-to-output coupling - prevents crosstalk between isolated data and control lines. |
| Industrial temperature range | –40°C to +100°C operation - eliminates need for thermal derating in enclosed industrial enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLP2366(TP,F) | Same SO8 footprint, but rated for 5 V supply (4.5–5.5 V); higher IFHL (5 mA max); identical 75 ns delay and 2500 Vrms isolation. | Requires 5 V logic domain; unsuitable for native 3.3 V systems without level-shifting. | Select when interfacing with 5 V microcontrollers or legacy industrial buses requiring 5 V compatibility. |
| ACPL-M61T-000E | SO5 package, single-channel, 10 MBd speed, 100 ns max delay, 3750 Vrms isolation, operates at 3.3 V with IFHL = 5 mA. | Lacks dual-channel integration; requires two units for same functionality; higher isolation voltage but slower timing. | Choose when board space permits separate channels and higher isolation voltage is prioritized over speed or density. |
Compared with TLP2166A(TP,F), the TLP2366(TP,F) shifts supply compatibility to 5 V at the cost of 3.3 V system readiness, while the ACPL-M61T-000E trades dual-channel integration and 15 MBd speed for higher isolation rating and single-channel simplicity - making TLP2166A(TP,F) optimal for compact, high-speed, 3.3-V–native industrial interfaces.

FAQ
What is the recommended bypass capacitor for TLP2166A(TP,F) and why is it required?
A 0.1 μF ceramic capacitor must be placed between pin 8 (VCC) and pin 5 (GND) for TLP2166A(TP,F), with total lead length ≤1 cm. This capacitor stabilizes the internal high-gain photodetector amplifier, preventing oscillation and ensuring consistent 75 ns propagation delay and clean logic transitions. Omission causes increased jitter, output instability, or failure to meet 15 MBd NRZ performance - verified in Toshiba's Test Circuit 3 and Application Note AN-102.
Does TLP2166A(TP,F) support 5 V logic inputs or is it strictly 3.3 V only?
TLP2166A(TP,F) is strictly a 3.3 V–optimized device: its recommended operating VCC is 3.0–3.6 V, and operation below 3.0 V risks elevated ICCH and output instability per Toshiba's Recommended Operating Conditions table. While absolute maximum VCC is 6 V, applying 5 V may exceed internal detector bias limits and invalidate the 75 ns timing spec. For 5 V systems, Toshiba recommends TLP2366(TP,F) instead.
How does the TLP2166A(TP,F) achieve ±15 kV/μs common-mode transient immunity?
TLP2166A(TP,F) achieves ±15 kV/μs CMTI through internal shielded die construction, optimized spacing between input and output bond wires, and differential sensing within the photodetector IC. The SO8 package includes internal conductive shielding layers between pins 1–4 (input side) and pins 5–8 (output side), validated per Test Circuit 6 in the datasheet. This architecture rejects fast dV/dt noise without requiring external filtering components.
Can TLP2166A(TP,F) be used in automotive applications?
TLP2166A(TP,F) is not qualified for automotive applications: it lacks AEC-Q100 certification, has no specified PPAP support, and its –40°C to +100°C operating range excludes extended automotive temperature grades (–40°C to +125°C or +150°C). Toshiba explicitly restricts use in transportation systems per its "Restrictions on Product Use" notice. For automotive isolation, consider AEC-Q100–qualified alternatives like Si86xx or ISO77xx series.
What is the meaning of the "(TP,F)" suffix in TLP2166A(TP,F)?
The "(TP,F)" suffix in TLP2166A(TP,F) indicates embossed tape packaging (TP) in a plastic carrier tape with cover tape (F), containing 2500 units per reel. "TP" denotes the tape type per Toshiba's packing specification; "F" specifies the cover tape material (static-dissipative plastic). This differs from tube (T) or bulk (B) packaging and is required for automated SMT placement - confirmed in Toshiba's Packing Specification Document Section 2 and Table 1.
