TLP2108 TOSHIBA PHOTOCOUPLER GaAℓAs Ired & PHOTO-IC TLP2108 Isolated Bus Drivers Unit: mm The Toshiba TLP2108 consists of GaAℓAs light emitting diodes and integrated high-gain, high-speed photodetectors. The TLP2108 is housed in the SO8 package. The photodetector has a totem-pole output stage that can source and sink current. The photodetector has an internal Faraday shield that provides a guaranteed common-mode transient immunity of ±10 kV/μs. The TLP2108 provides an inverting logic output. A noninverting logic version, the TLP2105, is also available. 8 7 6 5 1 2 3 4 3.95 ± 0.25 Microprocessor System Interfaces 5.1 ± 0.2 1.27 ± 0.15 0.38 z Inverting logic output (totem-pole output) z Guaranteed performance over -40 to 100°C z Power supply voltage: 4.5 to 20 V z Input threshold current: IFHL = 1.6 mA (max) z Switching time (tpLH / tpHL): 250 ns (max) z Common-mode transient immunity: ±10 kV/μs z Isolation voltage: 2500 Vrms 0.305 min 11-5K1 JEDEC ― JEITA ― TOSHIBA 11−5K1 Weight: 0.21 g (typ.)

Because rapid temperature changes can cause condensation to occur on stored devices, resulting in lead oxidation or corrosion, as a result, the solderability of the leads will be degraded. 6) When repacking devices, use anti-static containers. 7) Do not apply any external force or load directly to devices while they are in storage. 8) If devices have been stored for more than two years, even though the above conditions have been followed, it is recommended that solderability of them should be tested before they are used. 10 2008-11-26 TLP2108 RESTRICTIONS ON PRODUCT USE • Toshiba Corporation, and its subsidiaries and affiliates (collectively “TOSHIBA”), reserve the right to make changes to the information in this document, and related hardware, software and systems (collectively “Product”) without notice. • This document and any information herein may not be reproduced without prior written permission from TOSHIBA.
