SN74HC374ADBRG4

Flip Flops Overview

The SN74HC374ADBRG4 is an octal D-type flip-flop manufactured by Texas Instruments, belonging to the HC logic family. It features eight positive-edge-triggered D-type flip-flops with three-state outputs in a 20-pin SSOP package. The device operates within a supply voltage range of 2V to 6V and supports a maximum clock frequency of up to 35MHz at 5V. Key electrical parameters include a propagation delay of 23ns at 5V with 50pF load, output drive currents of ±5.2mA, and a static current of less than 1µA. It functions reliably across an operating temperature range of -40°C to +85°C.
