概述

Description

HCPL-2601 is a high-speed, optically isolated digital isolator (one-channel) from Avago/Broadcom. It transfers a logic signal across a galvanic isolation barrier using an infrared LED input and a photodetector with a fast output buffer, giving a TTL/CMOS-compatible output that is isolated from the input circuitry.
Key points:
- Isolation: several kilovolts RMS between input and output.
- Interface: input LED driven by a few mA; output side powered from Vcc (commonly 3.3–5 V) with a CMOS/TTL-compatible logic output.
- Performance: fast propagation delay (tens of nanoseconds range) with crisp rise/fall times and good common-mode transient immunity.
- Package: available in DIP-8 or SO-8.
Typical uses: isolating digital signals in microcontroller interfaces, motor drives, power supplies, and data acquisition systems. For exact pinout and electrical specs, consult the datasheet.

Features

Here are the key features of the HCPL-2601:
- Single-channel high-speed optocoupler with TTL/CMOS-compatible totem-pole output
- Optical isolation between input and output rated up to about 5 kV RMS
- Fast data transfer suitable for Mbps-range digital signaling
- Industrial temperature range: typically -40°C to +125°C
- Input: infrared LED (IF ~ a few mA to tens of mA); CTR guaranteed over temperature
- Packages: 8-pin DIP and surface-mount options available
- Built-in output transistor for direct compatible interfacing (no external pull-up required in many cases)
- Applications: microcontroller/digital I/O isolation, data communication, and isolating interfaces to high-voltage circuits
Note: For exact electrical parameters (IF range, CTR guarantees, propagation delay, and package variants) consult the specific HCPL-2601 datasheet.

Package

HCPL-2601 comes in an 8-pin DIP package; a surface-mount SO-8 version is also available.

Pinout

- Pin count: 8 pins (DIP-8).
- Function: A single-channel optocoupler that uses an LED input and a high-speed transistor output to provide galvanic isolation between input and output; TTL/CMOS-compatible digital output for isolating logic signals.

Manufacturer

Manufacturer: Broadcom Inc. (originally Avago Technologies; HCPL2601 is part of Avago’s HCPL optocoupler line).
