onsemi HCPL0601R1

Overview

HCPL0601R1 from Fairchild Semiconductor is a single-channel, high-speed logic gate optocoupler with 10 MBit/s data rate, strobable output, and open-collector configuration. It features AlGaAs LED input coupled to a bipolar-process photodetector logic gate, operates from -40°C to +85°C, and delivers 75 ns max propagation delay (TPLH/TPHL) at 5 V supply for ground loop elimination and digital isolation in industrial interfaces.

For engineers reviewing the HCPL0601R1 datasheet, pinout, applications, or equivalent options, this device is selected for high-noise immunity signal transmission requiring CMR >5000 V/µs at 50 V common-mode step, TTL/CMOS level compatibility, and compact SO8 packaging with strobable enable control.

Technical Context

The HCPL0601R1 integrates an AlGaAs LED emitter optically coupled to a high-speed bipolar logic gate detector with strobable enable input (pin 7). Its output stage uses open-collector bipolar transistors, enabling wired-OR bus configurations and direct interfacing with TTL, LSTTL, and 5 V CMOS loads.

It achieves 10 MBit/s operation via optimized internal noise shielding and fast switching characteristics: 75 ns max TPLH/TPHL, 12 ns tf (fall time), and 50 ns tr (rise time) under RL = 350 Ω, CL = 15 pF conditions. Common-mode transient immunity is rated at 5000 V/µs at |VCM| = 50 V, supporting robust performance in noisy power supply and motor drive environments.

FAQ

What is the maximum data rate supported by HCPL0601R1?

The HCPL0601R1 supports a maximum data rate of 10 MBit/s, verified under standard test conditions (VCC = 5 V, IF = 7.5 mA, RL = 350 Ω, CL = 15 pF). This rating is guaranteed across the full operating temperature range (-40°C to +85°C) and reflects its use as a high-speed logic gate optocoupler in digital isolation applications.

Does HCPL0601R1 require an external pull-up resistor on the output?

Yes, HCPL0601R1 has an open-collector output (pin 6), so an external pull-up resistor to VCC is required to establish a defined HIGH logic level. Recommended values range from 330 Ω to 4 kΩ depending on load capacitance and speed requirements; a 350 Ω resistor is used in standard timing tests.

What is the function of pin 7 (VE) on HCPL0601R1?

Pin 7 (VE) is the strobable enable input for HCPL0601R1. When VE is HIGH (≥2.0 V), the output responds to input signals; when VE is LOW (≤0.8 V), the output enters high-impedance state regardless of input. An internal pull-up eliminates the need for an external resistor.

Is HCPL0601R1 certified for safety standards?

Yes, HCPL0601R1 is UL recognized (File #E90700) and optionally certified to IEC60747-5-2 (VDE approval) when ordered with the 'V' suffix. Its 3750 VRMS isolation voltage and reinforced insulation structure meet requirements for industrial equipment safety compliance.

What bypass capacitor is required for HCPL0601R1?

A 0.1 µF ceramic or solid tantalum capacitor must be placed between pins 8 (VCC) and 5 (GND) of HCPL0601R1, mounted as close as possible to the device. This capacitor stabilizes the detector supply and is mandatory for achieving specified AC performance including propagation delay and noise immunity.
