electrical characteris t ics 12 5.6 lat c h-up test results test description: latch-up testing was perform e d at room a m bient using an imcs-4600 system whic h applies a stepped voltage to one pin per device with all other pins open except vdd and vss which were biased to 5 volts and ground respectively. testing was started at 5 .0 v (positive) or 0 v(negative), and the dut was biased for 0.5 seconds. if neither th e put current supply nor the device curren t supply reach ed the predefined lim it (dut= 0 ma , icc=100 ma), then the voltage was increased by 0.1 volts and the pin was tested again. this procedure was recommended by the je dec jc-40.2 cmos logic standardization committee. notes: 1. dut: device under test. 2. put: pin under test. icc measurem ent vcc dut gnd pin under m untested output open circuit untested input tied to v s upply + trigger sourc e + v su pp l y 1 source test ci rcuit : positive input/ output overvoltage /overcu rrent
