T2L compatible input and outputs @ Pulse widths stable and precise @ Pulse width voltage trimmable @ High output duty cycles @ 14-pin DIP package (.240 high) @ Available in pulse widths from 10 to 500ns @10 T2L fanout capacity design notes The DIP series Variable Pulse Generator Modules developed by Engineered Components Company have been designed to provide trimmable output pulse widths when triggered by variable width inputs. All required driving and output circuitry, as well as timing components, are contained in a 14-pin DIP package. These trimmable Pulse Generator 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 50C ground fixed environment, is inexcess of 3 million hours, These modules are compatible with Schottky T4L, Advanced CMOS and Fast circuits, 4 Phone: Z engineered components company 3580 Sacramento Drive, P. O, Box 8121, San Luis Obispo, CA 93403-8121 (805) 544-3800 low profile NCED CMOS TL COMPATIBLE VOLTAGE VARIABLE FAST RECOVERY PULSE GENERATOR The VERPG-ACT is available in 33 pulse widths from 10 to 500ns. These modules provide a stable yet trimmable output pulse for each positive input step. Pulse width adjustment is attained by adjusting the voltage at pin V, between 3 and 5V DC, with minimum pulse width occurring at 5V DC. The generated pulse is inverted internally to provide a negative pulse as an addi- tional output, It is necessary only that the input be held low for at least 10ns, then high for at least 10ns to obtain the desired output pulse, The duration of the positive input pulse, after this time, has no effect on output pulse width. No output pulse will occur on the negative input pulse transition. Pulse width tolerance is maintained as shown in the accompanying Part Number Table, when tested under the Test Conditions" shown, Pulse width is measured at the +1.5V level on both leading and trailing edge. Aise and fall times are less than 4ns, when measured from .75V to2.4V. These modules are capable of driving 10 Schottky T2L loads. Ternperature coefficient of pulse width for the majority of this product line is approximately + 500ppm/C over the operating temperature range of 40 to +85C. 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 provide positive standoff from the printed circuit board to permit solder-fillet formation and flush cleaning of solder-flux residues for improved reliability.DESIGN NOTES (continued) Marking consists of manufacturer's name, logo {EC2), 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 identification required by MIL-STD-202, Methad 215.

All modules can be operated up to the maximum pulse rate specified in the Part Number Table with pulse widths as low as 10ns and pulse spacing as low as 10ns. Since pulse width accuracies may be somewhat degraded at high pulse rates, itis suggested that the module be evaluated under the specific operating conditions. Special modules can be readily manufac- tured to improve accuracies and/or provide customer specified random pulse widths for specific applications, Catalog No. C/011590
