SN74AC74DR Description

Short technical summary and product information.

The SN74AC74DR is a dual positive-edge-triggered D-type flip-flop from Texas Instruments, part of the AC logic family. It offers a high clock frequency of 160 MHz and operates over a wide voltage range of 2V to 6V.

 

This device features two independent flip-flops, each with set (preset) and reset functions. The output type is complementary push-pull, with a maximum propagation delay of 6ns at 5V and 50pF. Input capacitance is rated at 3 pF.

 

Designed for surface mounting, the SN74AC74DR comes in a standard 14-SOIC package. Its operating temperature range is -40°C to 85°C (TA), making it suitable for various industrial applications. The device consumes a low supply current of 20 µA.

 

Key electrical characteristics include a maximum output current (IOL) of 24 mA and (IOH) of -24 mA. The input type is standard CMOS, and it features balanced outputs and positive input clamp diodes for enhanced performance.
