Toshiba Semiconductor and Storage TLP2110(TP,F)

Overview

TLP2110(TP,F) from Toshiba Electronic Devices & Storage Corporation is a dual-channel 5-Mbps low-power photocoupler in SO8 package, integrating infrared LED input stages and photo IC output stages with totem-pole outputs. It delivers ±25 kV/µs common-mode transient immunity, operates from 2.7 V to 5.5 V, consumes ≤0.6 mA supply current over −40 °C to 125 °C, and supports direct microcontroller drive with ≤1.0 mA threshold input current - used for isolated signal transmission in industrial inverters and battery management systems.

For engineers reviewing the TLP2110(TP,F) datasheet, TLP2110(TP,F) pinout, TLP2110(TP,F) application, or TLP2110(TP,F) equivalent, key selection criteria include guaranteed CMTI performance, dual-channel integration in SO8, low-threshold LED drive capability, isolation voltage rating (2500 Vrms), and compliance with UL 1577, cUL, and EN 60747-5-5 (with V4 option).

Technical Context

The TLP2110(TP,F) implements two independent optically isolated channels in a single SO8 package, each combining a GaAs infrared LED emitter and a photodiode-coupled high-speed IC detector with internal Faraday shield. Its totem-pole output stage provides both sourcing and sinking capability without external pull-ups.

It achieves 5 Mbps NRZ data transfer via precise timing control: max propagation delay of 250 ns (L/H and H/L), pulse width distortion ≤30 ns, and propagation skew ≤65 ns between channels - all specified across −40 °C to 125 °C at supply voltages from 2.7 V to 5.5 V.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-speed photocoupler applications.

Compared with TLP2110(TP,F), the TLP2310(TP,F) trades higher speed for increased power consumption, while the ACPL-K30T-000E sacrifices CMTI and output drive strength for marginal speed gain - making TLP2110(TP,F) the optimal balance for cost-sensitive, thermally constrained industrial isolation where 5 Mbps suffices.

FAQ

What is the maximum recommended operating temperature for the TLP2110(TP,F)?

The TLP2110(TP,F) is rated for continuous operation from −40 °C to +125 °C ambient temperature. This specification is validated across all electrical parameters including propagation delay, supply current, and CMTI. Operation beyond 125 °C risks parametric shift and accelerated aging; thermal derating is required above this limit. The TLP2110(TP,F) datasheet Rev.6.0 confirms this range in Section 3 (General) and Section 7 (Absolute Maximum Ratings).

Does the TLP2110(TP,F) require an external bypass capacitor?

Yes - a 0.1 µF ceramic capacitor must be placed between pin 5 (GND) and pin 8 (VDD) of the TLP2110(TP,F), located within 1 cm of the pins. This is explicitly mandated in Section 5 (Internal Circuit Note) and Section 8 (Recommended Operating Conditions) to stabilize the photo IC detector and prevent improper switching behavior. Omission causes erratic output transitions, especially at high data rates.

Is the TLP2110(TP,F) pin-compatible with the TLP2310(TP,F)?

No - although both use the SO8 package (11-5K1S), the TLP2110(TP,F) and TLP2310(TP,F) have identical pin assignments per Toshiba documentation (Section 4: Packaging and Pin Assignment). However, the TLP2310(TP,F) draws higher supply current and has different timing characteristics; it is not a drop-in replacement without verifying system-level power and timing margins. The TLP2110(TP,F) remains the preferred choice for sub-1 mA power budgets.

What safety certifications does the TLP2110(TP,F) hold?

The TLP2110(TP,F) is UL-recognized (UL 1577, File No. E67349), cUL-recognized (CSA Component Acceptance Service No. 5A, File No. E67349), and VDE-approved to EN 60747-5-5 when ordered with Option V4 (e.g., TLP2110(V4-TP,F)). The base TLP2110(TP,F) meets UL/cUL but not VDE unless V4 is specified. Certification details appear in Section 3 (Features) and Section 16 of the datasheet.

Can the TLP2110(TP,F) drive standard CMOS logic directly?

Yes - the TLP2110(TP,F) features totem-pole outputs (pins 6 and 7) capable of sourcing and sinking ≥3.2 mA, enabling direct interface with 3.3 V or 5 V CMOS inputs without external pull-up resistors. VOH is guaranteed ≥VDD − 0.1 V at IO = −20 µA, and VOL ≤ 0.1 V at IO = 20 µA (Section 9: Electrical Characteristics). This simplifies PCB layout and reduces BOM count compared to open-collector alternatives.
