TTLPWG 9901

TTLPWG Series FAST / TTL Pulse Width Generator Modules

14-Pin Package Commercial

and Mil-Grade Versions

FAST/TTL Logic Buffered

Precise Pulse Width Output

triggered by Rising Edge of Input

Operating Temperature Ranges

General: Triggered by the input's rising edge (input

pulse width 10 ns, min.), a pulse of specified width

will be generated at the output with a propagation

delay of 5 ± 2 ns (7 ± 2 ns, for inverted output). High-

to-low transitions will not trigger the unit. Designed

for output duty-cycle less than 50%.
