FUNCTIONAL DESCRIPTION
PIN DESCRIPTIONS
The PPG36F-series device is a 6-bit digitally programmable pulse
generator. The width, PWA, depends on the address code (A5-A0)
according to the following formula:
TRIG Trigger Input
OUT Non-inverted Output
OUT/ Inverted Output
A0-A5 Address Bits
RES Reset
PWA = PW0 + TINC * A
VCC +5 Volts
GND Ground
where A is the address code, TINC is the incremental pulse width of the
device, and PW0 is the inherent pulse width of the device. The incremental
width is specified by the dash number of the device and can range from 0.5ns through 10ns, inclusively.
RESET is held LOW during normal operation. When it is brought HIGH, OUT and OUT/ are forced into
LOW and HIGH states, respectively, and the unit is ready for the next trigger input. The address is not
latched and must remain asserted while the output pulse is active.

APPLICATION NOTES
DEVICE TIMING
POWER SUPPLY BYPASSING
The timing definitions and restrictions for the
PPG36F are shown in Figure 1. The unit is
activated by a rising edge on the TRIG input.
After a time, TTO (called the inherent delay), the
rising edge of the pulse appears at OUT. The
duration of the pulse is given by the above
equation. For the duration of the pulse, the
device ignores subsequent triggers. Once the
falling edge of the pulse has appeared at OUT,
an additional time, TOTR, is required before the
device can respond to the next trigger.
The PPG36F relies on a stable power supply to
produce repeatable pulses within the stated
tolerances. A 0.1uf capacitor from VCC to GND,
located as close as possible to each VCC pin, is
recommended. A wide VCC trace should
connect all VCC pins externally, and a clean
ground plane should be used.
INCREMENT TOLERANCES
Please note that the increment tolerances listed
represent a design goal. Although most
increments will fall within tolerance, they are not
guaranteed throughout the address range of the
unit. Monotonicity is, however, guaranteed over
all addresses.
At power-up, the state of the PPG36F is
unknown. Consequently, after power is applied,
the unit may not respond to input triggers for a
time equal to the maximum pulse width, PWT.
After this time, the unit will function properly. If
your application requires that the device function
immediately, issue a quick reset at power-up.
