Specifications subject to change without notice. EXPLANATION OF TEST LEVELS Test Level I – 100% Production Tested. II – 100% production tested at +25 °C, and sample tested at specified temperatures. AC testing done on sample basis. III – Sample Tested Only. IV – Parameter is guaranteed by design and characterization testing. V – Parameter is a typical value only. VI – All devices are 100% production tested at +25 °C. 100% production tested at temperature extremes for military temperature devices; guaranteed by design and character- ization testing for industrial devices.

Functional operability is not necessarily implied. Exposure to absolute maximum rating conditions for an extended period of time may affect device reliability. 2Typical thermal impedances (parts soldered to board): N Package (Plastic DIP): θ JA = 42°C/W; θJC = 10°C/W. R Package (SOIC): θ JA = 47°C/W; θJC = 10°C/W.
