OLH449 Datasheet Transistor Output Optocoupler

Manufacturer: Skyworks Solutions

Overview: DATA SHEET OLS449, OLC449, OLF449, OLH449: Radiation-Tolerant, Transistor Output Optocoupler with Base Connection Applications • Aerospace • Defense • Industrial •.

General Description

The OLx449 is designed for low input current applications that require optical isolation with a high CTR and low saturation VCE.

Each optocoupler Figure 1.

Block Diagram consists of an LED and NPN silicon phototransistor that is electrically isolated, but optically coupled inside a hermetic (LCC, FP, TO-5) or non-hermetic (Glob Top) package.

Key Features

  • High voltage electrical isolation.
  • High CTR assured over.
  • 55° to +125 °C.
  • Low input current: 1 mA.
  • Comparable to OLx249 family, but featuring higher CTR.
  • CMOS to LSTTL or TTL compatibility.
  • Various packages available to fit.
