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.
