These noise filter modules are of hybrid construction utilizing the

proven technologies of active integrated circuitry and of passive

networks utilizing capacitive, inductive and resistive elements. The

MTBF on these modules, when calculated per MIL-HDBK-217 for a

50⁰C ground fixed environment, is in excess of 3.5 million hours.

design notes

These “DIP Series” modules are packaged in a 14-pin DIP

housing, molded of flame-proof Diallyl Phthalate per MIL-M-14,

Type SDG-F, and are fully encapsulated in epoxy resin. Leads meet

the solderability requirements of MIL-STD-202, Method 208. Corner

standoffs on the housing of the thru-hole lead version and lead

design of the surface mount versions provide positive standoff from

the printed circuit board to permit solder-fillet formation and flush

cleaning of solder-flux residues for improved reliability.

The "DIP Series" Logic Noise Filter Modules developed by

Engineered Components Company has been designed for use in

T L systems employing data pulses of either a fixed width or a

minimum width. The filter module will produce a “1” at the output,

without significant change in width, only when a “1” appears at the

input for greater than the specified pulse width; all shorter pulses

will be suppressed. This operation will effectively eliminate sources

of stray noise pulses and should prove particularly effective in

eliminating transients created by crosstalk from leading edges of

fast rise time pulses.

Marking consists of the manufacturer's name, logo (EC ), part

number, terminal identification and date code of manufacture. All

marking is applied by silk screen process using white epoxy paint in

accordance with MIL-STD-130, to meet the permanency of identifi-

cation required by MIL-STD-202, Method 215.

The FNFM-TTL is offered in 20 pulse widths from 5ns to 200ns

for optimum noise pulse rejection in varous systems. Tolerance on

The output of the module will remain at state “0” for any

transient input pulses shorter than suppress times and will

change to state “1” for pulses longer than pass times. Input

pulse width is measure at the +1.5 level.

TEST CONDITIONS

1. All measurements are made at 25^oC.

2. Vcc supply voltage is maintained at 5.0V DC.

3. All units are tested using a FAST toggle-type positive input

pulse and one FAST T²L load at the output.

4. All units are tested to verify suppress and pass pulse widths,

as tabulated in the part number table.

Special modules can be readily manufactured to provide customer

specified times for specific applications.
