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.

16-Pin SMD Pkg. Unused leads are NOT removed.

To Specify SMD Package, Add "G" Suffix to P/N

Examples: PLDM4-1.25G, PLDM4-2G

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.
