Broadcom HCPL-2212 1-Channel Optocoupler 5Mbaud 8-Pin DIP

Broadcom HCPL-2212 1-Channel Optocoupler is a single-channel 8-pin DIP optocoupler rated at 5Mbaud, designed for signal isolation in electronic systems.

Overview

The HCPL-2212 integrates an AlGaAs LED optically coupled to a detector with a totem pole output stage. An integrated Schmitt trigger on the optical receiver input provides clean, logic-compatible waveforms directly, removing the need for external wave-shaping circuitry. Built-in hysteresis is included for noise immunity, and the totem pole output means no external pull-up resistor is required.

Key Features

• Common mode transient immunity of 10kV/µs at a common mode voltage of 1000V
• Operating temperature range from -40°C to 85°C
• Supply voltage (VCC) range of 4.5V to 20V
• Typical propagation delay of 150ns, with a maximum of 300ns over the full temperature range
• Low input current requirement
• Compatible with TTL, LSTTL, and CMOS logic families

Applications

The optocoupler is suited to isolating high-speed digital signals and breaking ground loops in a range of systems. Typical uses include isolation of high-speed logic systems and microprocessor interfaces, elimination of ground loops to prevent noise and signal corruption, replacement of pulse transformers in switching applications, and operation as a high-speed line receiver.

Physical Details

The device has a width of 3.3, a depth of 1.5, and a height of 4.3 (units not specified in the source data), with a weight of 1.497 g. Choose the Broadcom HCPL-2212 1-Channel Optocoupler when you need an 8-pin DIP optocoupler for high-speed signal isolation.
