SN74ABT273DBRG4

Flip Flops Overview

The SN74ABT273DBRG4 is an octal D-type flip-flop manufactured by Texas Instruments, belonging to the 74ABT logic series. It features a positive-edge trigger mechanism and non-inverting outputs within a 20-SSOP package. The device operates on a supply voltage range of 4.5V to 5.5V with a maximum clock frequency of 150 MHz. Key electrical parameters include a propagation delay of 6.8ns at 5V with 50pF load, output currents of 32mA high and 64mA low, and a static current of 400µA. It supports a main reset function and functions within a temperature range of -40°C to 85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type storage elements in a single integrated circuit.
• Positive-edge triggering ensures data capture occurs specifically on the rising edge of the clock signal.
• Non-inverting output polarity maintains logical consistency between input data states and output signals.
• Integrated main reset functionality allows for synchronous clearing of all stored data states.

Flip Flops Applications

• High-speed parallel data buffering in digital communication systems
• Register stages in microprocessor-based control architectures
• State storage within complex sequential logic circuits

Flip Flops Procurement Notes

Verify the complete part number including the G4 suffix to confirm RoHS compliance status. Ensure the SSOP package width matches the target PCB footprint dimensions. Confirm the specific revision level against the manufacturer's latest datasheet to guarantee pinout compatibility. Validate that the operating voltage requirements align with the system's 5V power rail specifications before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when high-speed performance is required alongside standard 5V logic levels. The ABT series offers superior speed compared to HC or HCT variants while maintaining compatible interface characteristics. Consider the 20-SSOP package for space-constrained surface-mount designs. Evaluate the 6.8ns propagation delay against system timing constraints to ensure adequate setup and hold times are met during operation.

Flip Flops Part Context

This device is part of the broader 74ABT family, which utilizes BiCMOS technology to achieve faster switching speeds than standard CMOS logic families. The SN74ABT273 serves as the non-inverting counterpart to the SN74ABT274, which provides inverted outputs. Both share identical internal architecture and electrical characteristics except for output polarity. The G4 suffix indicates environmental compliance with specific regulatory standards defined by the manufacturer.

Flip Flops Replacement Considerations

SN74ABT273DR is a direct functional equivalent with identical electrical specifications and pinout configuration. SN74ABT273DWRG4 offers the same core functionality but utilizes a TSSOP package variant instead of SSOP. Verify package dimensions carefully when substituting between SSOP and TSSOP formats to ensure mechanical fit.
