SN74LS73AN

Flip Flops Overview

The SN74LS73AN is a dual J-K flip-flop integrated circuit manufactured by Texas Instruments within the 74LS logic family. It features two independent edge-triggered circuits with active-low clear inputs, packaged in a 14-pin PDIP. The device operates on a supply voltage ranging from 4.75V to 5.25V and supports clock frequencies up to 45 MHz. Key electrical parameters include a maximum propagation delay of 20ns at 5V with 45pF load, high-level output current of 400µA, low-level output current of 8mA, and static current consumption of 6mA. It functions within an ambient temperature range of 0°C to 70°C.
