CUMULATIVE TOLERANCES: "Error" Tolerance is for Programmed Delays referenced to Initial Delay, Setting "000."
For example, the setting "111" delay of PLDM4-10 is 70.0 ± 3.0ns ref. to "000," and 74.0 ± 4.0ns referenced to the input.
_
ENABLE input (Pin 7) is active low. Output will be disabled ( low) when " E " is high.
INPUT FAN-IN: Input, pin 4, is loaded by the internal passive
network and 8 gate inputs (74F type). The source driving Pin 4
should be FAST/TTL (74S/74F) type or equivalent, and should not
be used to drive any load other than the delay line input.
