Product Summary

The HCPL0452 is a high speed transistor optocoupler. It consists of an AlGaAs LED optically coupled to a high speed photodetector transistor housed in a compact 8-pin small outline package. A separate connection for the bias of the photodiode improves, the speed by several orders of magnitude over conventional phototransistor optocouplers by reducing the base-collector capacitance of the input transistor. The HCPL0452 do not have the base bonded out to a lead for additional noise mar-gin. The HCPL0452 have two channels per package for optimum mounting density. Applications are (1)Line receivers; (2)Pulse transformer replacement; (3)Output interface to CMOS-LSTTL-TTL; (4)Wide bandwidth analog coupling.

Parametrics

HCPL0452 absolute maximum ratings: (1)storage temperature: -40 to 125℃; (2)operating temperature: -40 to 85℃; (3)average forward input current: 25mA; (4)peak forward input current: 50mA; (5)peak transient input current: 1A; (6)reverse input voltage: 5V.

Features

HCPL0452 features: (1)High speed:1 MBit/s ; (2)15kV/μs minimum common mode transient immunity at VCM = 1500V (HCPL0453/0534); (3)Open collector output ; (4)Guaranteed performance over temperature: 0°C to 70°C ; (5)U.L. recognized (File # E90700) ; (6)VDE0884 recognized:– approval pending for HCPL0530/0531/0453, ordering option V, e.g., HCPL0500V; (7)BSI recognized (file# 8661, 8662) – HCPL0452/0500/0501 only.
