Product details
Overview
VOH263A-X016 from Vishay Semiconductors is a dual-channel, 10 MBd high-speed optocoupler with open-drain outputs, 3.3 V/5 V dual supply support, LVTTL/LVCMOS compatibility, and guaranteed 15 kV/μs common-mode transient immunity (CMTI). It isolates digital signals in microprocessor interfaces and industrial bus systems while operating across –40 °C to +110 °C.
For engineers reviewing the VOH263A-X016 datasheet, VOH263A-X016 pinout, VOH263A-X016 application, or VOH263A-X016 equivalent, key selection criteria include propagation delay skew ≤40 ns, low-level output voltage ≤0.24 V at 3.3 V, input threshold current of 2–5 mA, and SMD-8 package compatibility with JEDEC J-STD-020C reflow profiles.
Technical Context
The VOH263A-X016 integrates two independent GaAs LED–photodetector channels with internal shielding to achieve ≥15 kV/μs CMTI. Each channel features an open-drain output stage compatible with 3.3 V or 5 V logic families and supports fanout of up to 5 TTL loads when RL = 1 kΩ.
Its switching performance is characterized under two supply ranges: 2.7–3.6 V and 4.5–5.5 V. Propagation delays (tPLH/tPHL) range from 20–90 ns depending on VCC and temperature, with pulse width distortion bounded to ≤10 ns and output rise/fall times as low as 2.3 ns (tr) and 2.3 ns (tf) respectively at optimal conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data rate | 10 MBd - supports high-speed serial communication links such as isolated UART or SPI clock domains. |
| CMTI | ≥15 kV/μs - ensures robust noise rejection in motor drives and power supply feedback loops with fast dv/dt transients. |
| Supply voltage | 2.7–3.6 V or 4.5–5.5 V - enables direct interface with both 3.3 V microcontrollers and legacy 5 V logic without level shifters. |
| Propagation delay skew | ≤40 ns - guarantees tight timing alignment between dual channels for synchronized signal isolation. |
| Low-level output voltage | ≤0.24 V at VCC = 3.3 V, IOL = 13 mA - ensures reliable logic-low recognition by downstream CMOS inputs. |
| Input threshold current | 2–5 mA - defines minimum LED drive needed to guarantee output transition, enabling efficient current-limited driving. |
| Isolation voltage | 5000 VRMS (1 min) - meets UL1577 and DIN EN 60747-5-5 safety requirements for reinforced insulation in industrial equipment. |
Pinout & Package
SMD-8 surface-mount package (JEDEC MS-012AC), 9.68 mm × 6.5 mm footprint, 2.54 mm lead pitch, 0.35 mm nominal lead thickness, and 7 mm creepage/clearance distance per safety standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed optocoupler applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si87xxAC-B-IS | Capacitive isolation; 15 MBd max; 3.3 V only; lower CMTI (10 kV/μs); different pinout. | Requires redesign for supply voltage and layout; not drop-in for 5 V systems or SMD-8 footprint. | Select when higher speed or lower power consumption outweighs need for optical isolation heritage and 5 V compatibility. |
| HCPL-063L | Optical isolation; 10 MBd; 5 V only; DIP-8 package; CMTI = 15 kV/μs; slightly higher tPLH/tPHL (max 100 ns). | Requires through-hole assembly; unsuitable for automated SMT production or space-constrained PCBs. | Select when legacy DIP-8 compatibility or availability from alternate distributors is prioritized over SMT manufacturability. |
Compared with Si87xxAC-B-IS and HCPL-063L, the VOH263A-X016 uniquely combines SMD-8 packaging, dual 3.3 V/5 V supply support, and guaranteed 15 kV/μs CMTI in a single 10 MBd optocoupler-making it optimal for new industrial designs requiring mixed-voltage interoperability and automated assembly.

FAQ
What is the maximum data rate supported by the VOH263A-X016?
The VOH263A-X016 supports a maximum data rate of 10 MBd, verified across its full operating temperature range (–40 °C to +110 °C) and both 3.3 V and 5 V supply configurations. This rating is confirmed by propagation delay specifications (tPLH/tPHL ≤90 ns) and pulse width distortion limits (≤10 ns), ensuring reliable high-speed serial communication in isolated interfaces.
Does the VOH263A-X016 require external pull-up resistors on its outputs?
Yes, the VOH263A-X016 features open-drain outputs (VO1 and VO2), so external pull-up resistors are required to establish valid high-level logic states. Recommended values range from 330 Ω to 4 kΩ depending on speed and load requirements; 1 kΩ is typical for TTL fanout of five loads. No internal pull-ups are integrated.
What safety certifications does the VOH263A-X016 hold?
The VOH263A-X016 carries UL1577 (5000 VRMS, 1 min) and cUL recognition, and is available with optional DIN EN 60747-5-5 (VDE 0884-5) certification for reinforced insulation. The VOH263A-X016 variant itself is UL/cUL certified and rated for 630 Vpeak repetitive peak isolation voltage per VDE standards.
Can the VOH263A-X016 operate with both 3.3 V and 5 V logic families simultaneously?
No-the VOH263A-X016 uses a single VCC pin (Pin 7) that must be set to either 2.7–3.6 V or 4.5–5.5 V; it does not support mixed-supply operation on the output side. However, its LVTTL/LVCMOS compatibility means the same VOH263A-X016 device can be deployed in either 3.3 V or 5 V systems without redesign, simplifying inventory management.
What is the creepage and clearance distance of the VOH263A-X016 package?
The VOH263A-X016 in SMD-8 package provides ≥7 mm creepage and ≥7 mm clearance distances, compliant with pollution degree 2 and comparative tracking index (CTI) ≥175 per IEC 60664-1. These dimensions satisfy reinforced insulation requirements for 300 V working voltage in industrial applications.
