SN74AHCT74DR Description

Short technical summary and product information.

The SN74AHCT74DR is a dual positive-edge-triggered D-Type flip-flop manufactured by Texas Instruments. This component is designed for digital logic applications, offering two independent flip-flop elements within a single package.

 

Key electrical specifications include a maximum clock frequency of 140 MHz and a maximum propagation delay of 8.8ns at 5V with a 50pF load. It operates within a voltage range of 4.5V to 5.5V and consumes a low supply current of 2 µA. The inputs are TTL-compatible, and the output type is complementary.

 

This flip-flop features Set (Preset) and Reset functions, allowing for direct control of the output states regardless of the clock input. The device is housed in a 14-SOIC surface-mount package, measuring 0.154 inches (3.90mm) in width. The operating temperature range is from -40°C to 125°C (TA).

 

Ideal for various digital circuit designs requiring data storage or synchronization, the SN74AHCT74DR provides reliable performance in a standard package suitable for automated assembly processes.
