SN added the grades for the SC70 package in the table heads for the respective voltage option. SN made some minor edits and addeda new para. SN composed with all the edits. SN all text edits done. waiting for art load. changed only the package name. Need to find out from Khy about T/R qty. SN just added the new row for output hysteresis on the table and a new footnote. Will recompose after changing the package diagram. SN minor edits from KhyV. SN latest file from Tim. Edited the sgml file from 8/29/97. fixed some avo attributes since the file was older SOT-23 TO-92 SC V 2.500V 3.000V 4.096V 5.000V 8.192V V (-2.5) (A 25 ) 0.1 ( ) (10Hz 10kHz) 35 V rms ( ) 60 A 15mA ppm/ ( ) SOT-23 TO-92SC70 SC70 * 2 Top View See NS Package Number MF03A (JEDEC Registration TO-236AB) Bottom View See NS Package Number Z03A * 1 Top View See NS Package Number MAA05A National Semiconductor Corporation DS JP 1
