FUNCTIONAL DESCRIPTION

PIN DESCRIPTIONS

The PPG33F-series device is a 3-bit digitally programmable pulse

TRIG Trigger Input

generator. The width, PWA, depends on the address code (A2-A0)

OUT Non-inverted Output

according to the following formula:

OUT/ Inverted Output

A0-A2 Address Bits

PWA = PW0 + TINC * A

RES Reset

VCC +5 Volts

where A is the address code, TINC is the incremental pulse width of the

GND Ground

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 50ns,

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.

SERIES SPECIFICATIONS

• Programmed pulse width tolerance: 5% or 1ns,

whichever is greater

• Inherent width (PW0): 9ns typical

• Inherent delay (TTO): 3.5ns ± 2ns

• Operating temperature: 0° to 70° C

• Supply voltage VCC: 5VDC ± 5%

• Supply current: ICC = 41ma typical
