SN54LS74AJ Description

Short technical summary and product information.

The SN54LS74AJ from Texas Instruments is a dual D-type positive-edge-triggered flip-flop designed for high-speed applications. Each flip-flop features independent preset and clear inputs that allow the outputs to be set or reset regardless of other inputs. When preset and clear are inactive, data at the D input is transferred to the outputs on the positive-going edge of the clock pulse.

 

This device operates within a military temperature range of -55°C to 125°C. Key electrical specifications include a maximum clock frequency of 25 MHz, an IOL of 8 mA, and an IOH of -0.4 mA. The supply current is a maximum of 8000 µA. Propagation delays range from 10 ns to 50 ns.

 

The SN54LS74AJ is available in various package options, including CDIP (J), CFP (W), LCCC (FK), as well as plastic and ceramic DIPs. These devices are suitable for applications requiring reliable digital logic functions within demanding environmental conditions.
