FUNCTIONAL DESCRIPTION
The PDU17F-series device is a 7-bit digitally programmable delay line.
The delay, TD
A
, from the input pin (IN) to the output pins (OUT, OUT/)
depends on the address code (A6-A0) according to the following formula:
TD
A
= TD
0
+ T

where A is the address code, T
INC
is the incremental delay of the device,
and TD
0
is the inherent delay of the device. The incremental delay is
specified by the dash number of the device and can range from 0.5ns through 10ns, inclusively. The
enable pins (EN/) are held LOW during normal operation. These pins must always be in the same state
and may be tied together externally. When these signals are brought HIGH, OUT and OUT/ are forced
into LOW and HIGH states, respectively. The address is not latched and must remain asserted during
normal operation.
