SWITCHING CHARACTERISTICS**
Characteristic
Output Rise and Fall Time
t TLH , t THL = (1.5 ns/pF) C L + 25 ns
t TLH , t THL = (0.75 ns/pF) C L + 12.5 ns
t TLH , t THL = (0.55 ns/pF) C L + 9.5 ns
Turn–Off, Turn–On Delay Time — A or B to Q or Q
t PLH , t PHL = (1.7 ns/pF) C L + 240 ns
t PLH , t PHL = (0.66 ns/pF) C L + 87 ns
t PLH , t PHL = (0.5 ns/pF) C L + 65 ns
Turn–Off, Turn–On Delay Time — A or B to Q or Q
t PLH , t PHL = (1.7 ns/pF) C L + 620 ns
t PLH , t PHL = (0.66 ns/pF) C L + 257 ns
t PLH , t PHL = (0.5 ns/pF) C L + 185 ns
Input Pulse Width — A or B
Output Pulse Width — Q or Q
(For C X < 0.01 µF use graph for
appropriate V DD level.)
Output Pulse Width — Q or Q
(For C X > 0.01 µF use formula:
t W = 0.2 R X C X Ln [V DD – V SS ])†
Pulse Width Match between Circuits in the same
package
Reset Propagation Delay — Reset to Q or Q
Retrigger Time
External Timing Resistance
External Timing Capacitance
† R X is in Ohms, C X is in farads, V DD and V SS in volts, PW out in seconds.
* If C X > 15 µF, Use Discharge Protection Diode D X , per Fig. 9.
** The formulas given are for the typical characteristics only at 25 _ C.
#Data labelled "Typ" is not to be used for design purposes but is intended as an indication of the IC's potential performance.
