TTL Gated Oscillators

These gated oscillators permit synchronization of the output square wave with the high-tolow transition of the enable input. When the enable is high, the output is held high. The output will start with a high-to-low transition one half-cycle after the input trigger. The output frequency tolerance is ± 3%.

TTL Pulse Width Generator Modules

Triggered by the inputs 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 dutycycle less than 50%.

TTL Pulse Width Discriminators

Input pulse widths greater than the Nominal value (XX in ns from P/N TTLPD-XX) of the module, will propagate with delay of (XX + 5ns) ± 5% or 2 ns, whichever is greater. Output pulse width will follow the input width ± 7% or 4 ns, whichever is greater. Input pulse widths less than the Nominal value will be suppressed.
