Texas Instruments SN74AHCT273/SN74AHCT273-Q1 Octal D-Type Flip-Flops

Texas Instruments SN74AHCT273/SN74AHCT273-Q1 Octal D-Type Flip-Flops include 8 positive-edge-triggered D-type flip-flops with a direct Clear (CLR) input. These devices are designed to store and synchronize digital data across eight channels. Each flip-flop has a dedicated data input (D) and output (Q), while all flip-flops share a common clock (CLK) and clear (CLR) signal. The outputs change state on the rising edge of the clock signal, provided the clear input is inactive (high). When the clear input is asserted (low), all outputs are asynchronously reset to low, regardless of the clock or data inputs. Typical applications include buffers and storage registers, servers, network switches, memory systems, databases, pattern generators, and shift registers.
