SN74LS273DWR

Flip Flops Overview

The SN74LS273DWR is an octal D-type flip-flop manufactured by Texas Instruments, belonging to the standard 74LS logic family. It features eight independent positive-edge-triggered D flip-flops with a master reset input. The device operates within a supply voltage range of 4.75V to 5.25V and supports a maximum clock frequency of 30 MHz. Propagation delay is specified at 27 ns, with output drive capabilities of 8 mA low-level current and -400 µA high-level current. It is housed in a 20-pin SOIC package.

Flip Flops Feature Summary

• Contains eight independent positive-edge-triggered D-type flip-flops for parallel data storage
• Includes a dedicated master reset input to clear all outputs simultaneously
• Provides non-inverting true outputs compatible with standard TTL logic levels

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• General-purpose register applications in digital systems
• Data buffering and latching interfaces for microprocessors

Flip Flops Procurement Notes

Verify that the specific ordering suffix matches the required package type and tape-and-reel specifications. Confirm RoHS compliance status and ensure the component meets the intended operating temperature range requirements before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when designing systems requiring octal storage with a single control line. Ensure the design accommodates the 74LS family power consumption characteristics and verify that the 5V logic level compatibility aligns with the rest of the system architecture.

Flip Flops Part Context

This part belongs to the widely used 74LS series of logic integrated circuits, known for their balanced performance and cost-effectiveness in general-purpose digital logic applications. The SN74LS273 variant specifically provides octal storage functionality within this established technology family.

Flip Flops Replacement Considerations

Compatible substitutes include the SN74LS273N (PDIP package) and SN74LS273NSR (SOIC tape-and-reel). Verify pinout compatibility and electrical parameter equivalence before implementing any cross-package replacements.
