Closest I can find is a Quad Telecom relay driver DS3628 (not ideal, 4x=20 BC557 is more use!) No-one any idea of octal PNP transistor array with at least -30V rating? (Telcom rated parts fine). --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
