TTL Pulse Width

Generator Modules

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%.

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 sup-

pressed.

TTL Gated

Oscillators

These gated oscillators permit synchroniza-

tion of the output square wave with the high-to-

low 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%.
