Flip Flops datasheet and documents for SN74LS74ANS

SN74LS74ANS

Flip Flops Overview

The SN74LS74ANS is a dual D-type flip-flop integrated circuit from the Texas Instruments SN74LS74A series. It features two independent positive-edge-triggered D-type flip-flops with dedicated preset and clear inputs. The device operates within a supply voltage range of 4.75 V to 5.25 V, utilizing TTL logic levels. Key electrical parameters include a propagation delay of 40 ns at 5 V, a high-level output current of -0.4 mA, and a low-level output current of 8 mA. It is housed in a 14-pin PDIP package and supports an operating temperature range of 0°C to +70°C.

Flip Flops Feature Summary

Contains two independent D-type flip-flops triggered by the positive edge of the clock signal.
Features active-low asynchronous preset and clear inputs for direct control of output states.
Provides complementary Q and /Q outputs for each flip-flop stage.

Flip Flops Applications

Data storage and register circuits
Shift registers
Frequency division circuits

Flip Flops Procurement Notes

Verify the specific suffix 'ANS' against the manufacturer's official documentation to confirm the exact package type (PDIP) and commercial grade specifications. Ensure compatibility with existing PCB footprints and thermal requirements before finalizing procurement decisions.

Flip Flops Selection Notes

Select this component when designing systems requiring dual independent data storage elements with asynchronous control capabilities. Consider the 40 ns propagation delay and standard TTL drive strength for timing analysis. Verify that the through-hole PDIP-14 package aligns with the target assembly technology constraints.

Flip Flops Part Context

This part belongs to the widely used 74LS (Low-power Schottky) logic family, known for balanced speed and power consumption. The SN74LS74A variant represents an improved version of the original 74LS74, offering enhanced performance characteristics while maintaining pin-out compatibility with legacy designs.

Flip Flops FAQ

How do the preset and clear inputs function?

The preset and clear inputs are active-low and asynchronous. A low signal on either input immediately sets or resets the output, overriding the clock and data inputs.
