Data SheetHMC674LC3C/HMC674LP3ETIMING DESCRIPTIONSTable 6. ParameterSymbolDescription Input to Output High Delay tPDH The propagation delay measured from the time the input signal crosses the reference (± the input offset voltage) to the 50% point of an output low to high transition. Input to Output Low Delay tPDL The propagation delay measured from the time the input signal crosses the reference (± the input offset voltage) to the 50% point of an output high to low transition. Latch Enable (LE/LE) to Output High Delay tPLOH The propagation delay measured from the 50% point of the latch enable (LE/LE) signal high to low transition to the 50% point of an output low to high transition. Latch Enable (LE/LE) to Output Low Delay tPLOL The propagation delay measured from the 50% point of the latch enable (LE/LE) signal high to low transition to the 50% point of an output high to low transition. Minimum Hold Time tH The minimum time after the positive transition of the latch enable (LE/LE) signal that the input signal must remain unchanged to be acquired and held at the outputs. Minimum Latch Enable (LE/LE) Pulse Width tPL The minimum time that the latch enable (LE/LE) signal must be low to acquire an input signal change. Minimum Setup Time tS The minimum time before the positive transition of the latch enable (LE/LE) signal that an input signal change must be present to be acquired and held at the outputs. Output Rise Time tR The amount of time required to transition from a low to a high output as measured at the 20% and 80% points. Output Fall Time tF The amount of time required to transition from a high to a low output as measured at the 20% and 80% points. Input Overdrive Voltage VOD The difference between the input voltages (VINP and VINN).
