SN74F74NSR TI Flip-Flop IC | 14-SO | Dual D-Type, Positive Edge

Product Overview

The SN74F74NSR is a dual D-type positive-edge-triggered flip-flop from Texas Instruments, featuring individual data (D), clock (CP), set (SD), and reset (RD) inputs. It is designed for high-speed digital systems, offering typical clock frequency up to 100 MHz. The device is housed in a 14-pin SOP package (NSR suffix) and operates over a wide supply voltage range of 4.5V to 5.5V. With its balanced propagation delays and high noise immunity, the SN74F74NSR is ideal for register, counter, and data storage applications in industrial and consumer electronics.
