FUNCTIONAL DESCRIPTION

The PDU15F-series device is a 5-bit digitally programmable delay line.

The delay, TDA, from the input pin (IN) to the output pins (OUT, OUT/)

depends on the address code (A4-A0) according to the following formula:

TDA = TD0 + TINC * A

where A is the address code, TINC is the incremental delay of the device,

and TD0 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 20ns, 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.
