Frequently Asked Questions
What is the function of the SN74AHCT273PWR-P?
The SN74AHCT273PWR-P is an 8-bit octal D flip-flop that captures 8 bits of input data on the rising edge of the clock signal and holds them at the outputs until the next clock edge or until the active-low asynchronous clear is asserted.
What supply voltage and input levels does the SN74AHCT273PWR-P support?
It operates from a 5V supply and has AHCT-family 5V-tolerant inputs that accept standard TTL logic levels (VIH ≥ 2.0V, VIL ≤ 0.8V), making it directly compatible with both CMOS and TTL-output devices without level-translation circuits.
What package does the SN74AHCT273PWR-P come in?
The SN74AHCT273PWR-P is housed in a 20-pin TSSOP (Thin Shrink Small Outline Package), providing a compact surface-mount footprint with a fine 0.65 mm pitch suitable for dense PCB layouts in space-constrained designs.
What are common applications for the SN74AHCT273PWR-P?
Common applications include bus address latching, output port registers on microcontrollers and FPGAs, pipeline data storage stages, LED segment display drivers, and any digital system requiring synchronous 8-bit data capture with an asynchronous hardware reset.
