SN74ABT273DW

Flip Flops Overview

The SN74ABT273DW is an octal D-type flip-flop from the Texas Instruments ABT logic series, housed in a 20-pin SOIC package. It operates within a supply voltage range of 4.5 V to 5.5 V and features non-inverting outputs with TTL input and output compatibility. The device exhibits a maximum propagation delay of 6.8 ns at 5 V with 50 pF load, supporting clock frequencies up to 150 MHz. Output drive capabilities include -32 mA high-level and 64 mA low-level currents. It functions across an industrial temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type edge-triggered storage elements in a single integrated circuit.
• ABT technology ensures high-speed performance with low power consumption and strong output drive characteristics.
• TTL-compatible inputs and outputs facilitate direct interfacing with standard digital logic systems.

Flip Flops Applications

• High-speed data register applications requiring parallel-to-serial or serial-to-parallel conversion.
• Buffering and latching operations in microprocessor-based system architectures.
• General-purpose memory storage elements in digital control circuits.

Flip Flops Procurement Notes

Verify the specific ordering suffix to confirm the exact package variant and tape/reel specifications, as the base part number may correspond to multiple packaging options. Confirm RoHS compliance status and environmental certifications against the latest manufacturer datasheet before finalizing procurement orders. Ensure the selected component matches the required thermal and electrical operating conditions for the target application environment.

Flip Flops Selection Notes

Select this component when an octal D-type flip-flop with ABT speed and 5V operation is required. Compare against SN74ABT273N for through-hole needs or SN74LVTH273 variants if lower voltage operation is necessary. Consider the 20-pin SOIC footprint constraints and verify that the 6.8 ns propagation delay meets the system timing requirements.

Flip Flops Part Context

This component belongs to the SN74ABT273 family of octal D-type flip-flops manufactured by Texas Instruments. The ABT series utilizes advanced bipolar technology to deliver high-speed switching with reduced power dissipation compared to older logic families. The DW suffix specifically denotes the small-outline integrated circuit (SOIC) surface-mount package format.
