FUNCTIONAL DESCRIPTION
The PDU13F-series device is a 3-bit digitally programmable delay line.
The delay, TD
depends on the address code (A2-A0) according to the following formula:
where A is the address code, T
and TD
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.

... PDU13F ADDRESS UPDATE The PDU13F is a memory device. As such, special precautions must be taken when changing the delay address in order to prevent spurious output signals. The timing restrictions are shown in Figure 1. After the last signal edge to be delayed has appeared on the OUT pin, a minimum time required before the address lines can change ...
