Product specification

74HC/HCT5555

Notes

1. One stage selected.

2. It is possible to retrigger directly after the trigger pulse, however the pulse will only be extended, if the time period

exceeds the clock input cycle time divided by 2.

3. One stage selected. The termination of the output pulse remains synchronized with respect to the falling edge of the

RS clock input.

4. One stage selected. The termination of the output pulse is no longer synchronized with respect to the falling edge of

the RS clock input.
