This document describes the features and characteristics of HCMOS compatible, high CMR, 10 MBd optocouplers. It includes HCMOS/LSTTL/TTL performance compatibility, high speed, and AC/DC performance specified over the industrial temperature range.
The HCPL‑261A and HCPL‑061A families are HCMOS/LSTTL/TTL compatible optocouplers offering 10 MBd typical data rates and excellent common‑mode rejection (CMR). They are available in 8‑pin DIP and SO‑8 packages and meet UL1577, CSA and IEC/EN/DIN EN 60747‑5‑2 safety standards.
Key features include low input current (3 mA), high isolation voltage, and optional options for UL rating, lead‑free construction, and surface‑mount packaging. The datasheet provides ordering information, electrical specifications, and recommended drive circuits for optimal CMR performance. This manual is written in Chinese.
| Typical Data Rate | 10 MBd |
|---|---|
| Minimum Common Mode Rejection (HCPL‑261A) | 1000 V/µs at VCM = 50 V |
| Maximum Common Mode Rejection (HCPL‑261N) | 15 kV/µs at VCM = 1000 V |
| Operating Temperature Range | -40 °C to +85 °C |
| Supply Voltage (VCC) | 4.5 V – 5.5 V |
| Average Input Current | 10 mA |
| Output Collector Current (per channel) | 50 mA |
| Output Power Dissipation (per channel) | 60 mW |
| Isolation Voltage (UL rating) | 5000 V rms for 1 min |
| Recommended Bypass Capacitor | 0.1 µF between pins 5 and 8 |
A 0.1 µF capacitor should be placed between pins 5 and 8.
The devices operate with a supply voltage (VCC) between 4.5 V and 5.5 V.
The typical low‑input current is 3 mA.
