FUNCTIONAL DESCRIPTION

The PDU13F-series device is a 3-bit digitally programmable delay line.

depends on the address code (A2-A0) according to the following formula:

specified by the dash number of the device and can range from 0.5ns

through 50ns, inclusively. The enable pin (EN/) is held LOW during

normal operation. When this signal is 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.
