FUNCTIONAL DESCRIPTION
The PDU10256H-series device is an 8-bit digitally programmable delay line. The delay, TD
input pin (IN) to the output pin (OUT) depends on the address code (A7-A0) according to the following
formula:
where A is the address code, T
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 pin (ENB) is held LOW during normal operation. When this
signal is brought HIGH, OUT is forced into a LOW state. The address is not latched and must remain
asserted during normal operation.

... PDU10256H ADDRESS UPDATE The PDU10256H 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, ...
