Description

These devices are single channel, hermetically sealed,

voltage/current threshold detection optocouplers. The

products are capable of operation and storage over the

full military temperature range and can be purchased as

either standard product, or with full MIL-PRF-38534 Class

Level H or K testing, or from the DLA Standard Micro-cir-

cuit Drawing

(SMD) 5962-89477. All devices are manu-

factured and tested on a MIL-PRF-38534 certified line

and are included in the DLA Qualified Manufacturers List,

QML-38534 for Hybrid Microcircuits.
