(ex: hsh1205d can be used as a 10 vdc output.) i nhibit f unction when an open collector ttl logic low is applied to the inhibit termi- nal, pin 7, the converter shuts down and lowers the output voltage to near zero and input current to as low 5 ma. leaving the terminal open or applying an open collector ttl logic high will enable the converter. mil-std-461 use interpoint?s fmsa-461 emi filter to pass the ce03 requirements of mil-std-461c. c onvenient p ackaging the hsh series converters are packaged in hermetically sealed metal cases which provide emi/rfi shielding and protection from the environment. size (max.): 0.980 x 0.805 x 0.270 inches (24.89 x 20.45 x 6.86 mm) weight: 12 grams max. screening: hsh standard or hsh es
