FUNCTIONAL DESCRIPTION

input pin (IN) to the output pin (OUT) depends on the address code (A7-A0) according to the following

formula:

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.
