5.5 ESD Test Results
Test Description : ESD Testing was performed on a Zapmaster system using the HumanBody -Model (HBM) and Machine-Model (MM), according to MIL_STD 883 and EIAJ IC_121 respectively. Human-Body-Model stress devices by sudden application of a high voltage supplied by a 100 PF capacitor through 1.5 Kohm resistance. Machine-Model stresses devices by sudden application of a high voltage supplied by a 200 PF capacitor through very low (0 ohm) resistance Test circuit & condition Zap Interval : 1 second Number of Zaps : 3 positive and 3 negative at room temperature Critera : I-V Curve Tracing Model HBM MM Model Vdd, Vss, I/C Vdd, Vss, I/C S/S 15 15 TARGET 4000V 200V Results Pass Pass

5.6 Latch-Up Test Results
Test Description: Latch-Up testing was performed at room ambient using an IMCS-4600 system which 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 the PUT current supply nor the device current supply reached the predefined limit (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 JEDEC JC-40.2 CMOS Logic standardization committee. Notes: 1. DUT: Device Under Test. 2. PUT: Pin Under Test.
