The maximum clock frequency of the SN74HCT273PWR is 30 MHz.
To ensure that the outputs of the SN74HCT273PWR are in a known state during power-up, you can use the asynchronous reset (CLR) input. Asserting the CLR input low during power-up will reset the outputs to a known state.
Yes, the SN74HCT273PWR is compatible with 5V systems. It is a CMOS device with a wide operating voltage range of 4.5V to 5.5V.
To reduce power consumption in the SN74HCT273PWR, you can use the following techniques: reduce the clock frequency, minimize the number of transitions on the inputs, and use the power-down mode (if available).
The SN74HCT273PWR is rated for operation over a temperature range of -40°C to 125°C. However, the device's performance and reliability may degrade at higher temperatures. Consult the datasheet for more information on temperature-related specifications.
