Description

The SN74AHCT273PWR is an octal D-type flip-flop designed by Texas Instruments, which operates with a supply voltage range of 4.5V to 5.5V. It features eight data inputs (D0-D7) and eight corresponding outputs (Q0-Q7), along with a clock input (CLK) and a clear input (CLR). The flip-flop captures the state of the data inputs on the rising edge of the clock signal and holds that state until the next clock pulse.
This device is part of the AHCT family, meaning it is optimized for high-speed performance and is compatible with both TTL and CMOS logic levels, making it versatile for various digital applications. It is useful in data storage, control applications, and state machines. The SN74AHCT273PWR is housed in a TSSOP-20 package, providing a compact footprint for space-constrained designs. Its robust performance and reliable functionality make it suitable for both consumer electronics and industrial applications.

Features
