9.2.1.4 Timing Considerations

The SN74HCS596-Q1 is a clocked device. As such, it requires special timing considerations to ensure normal operation.

Primary timing factors to consider:

• Maximum clock frequency: the maximum operating clock frequency defined in Timing Characteristics is the maximum frequency at which the device is guaranteed to function. This value refers specifically to the triggering waveform, measuring from one trigger level to the next.
• Pulse duration: ensure that the triggering event duration is larger than the minimum pulse duration, as defined in the Timing Characteristics.
• Setup time: ensure that the data has changed at least one setup time prior to the triggering event, as defined in the Timing Characteristics.
• Hold time: ensure that the data remains in the desired state at least one hold time after the triggering event, as defined in the Timing Characteristics.
