14-pin DIP
Delay Characteristics measured at Vcc = 5.0V, 25oC, with 15 pf load per tap @ 1.5V level.
Delay Tolerance +1.5 ns or 5%, whichever is greater.
Rise time measured @ 0.8V to 2.0V levels.
For minimum input pulse width -- contact factory. Designs with pulse widths of less than
15% of delay are available.
For TTL delay
lines qualified
