SN74ABT273PWRE4

Flip Flops Overview

The SN74ABT273PWRE4 is an octal D-type edge-triggered flip-flop from the Texas Instruments ABT logic series. It features eight independent D-type flip-flops with positive-edge triggering and a clear input. The device operates within a supply voltage range of 4.5 V to 5.5 V, utilizing TTL-compatible inputs and outputs. It provides high drive capability with output currents of -32 mA (high) and 64 mA (low). The propagation delay is specified at 6.8 ns. The component is housed in a 20-TSSOP package and supports surface-mount installation.

Flip Flops Feature Summary

• Octal configuration containing eight independent D-type edge-triggered flip-flops for parallel data storage
• Positive-edge triggering mechanism synchronized by the clock signal
• High-drive TTL-compatible outputs providing significant current sourcing and sinking capabilities
• ABT technology ensures fast propagation delays while maintaining compatibility with standard logic levels

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register banks for temporary data storage in digital systems
• Buffering interfaces between different logic families
• State holding elements in sequential logic designs

Flip Flops Procurement Notes

Verify the specific suffix 'E4' indicates RoHS compliance and manufacturing origin details as per Texas Instruments standards. Confirm the TSSOP-20 package dimensions match the target PCB footprint requirements. Ensure the operating temperature range of -40°C to +85°C aligns with the environmental conditions of the intended application. Cross-reference the datasheet revision history to confirm electrical characteristics have not changed in recent updates.

Flip Flops Selection Notes

Select this component when an octal register with high drive strength and moderate speed is required. The ABT series offers a balance between the speed of ALS logic and the low power consumption of LVC logic. Consider the 4.5V to 5.5V supply requirement; if lower voltage operation is needed, alternative LVTH or HC series devices should be evaluated. The TSSOP package is suitable for automated surface-mount assembly processes.

Flip Flops Part Context

This part belongs to the SN74ABT273 family of octal D-type flip-flops. The 'E4' suffix typically denotes a specific manufacturing variant, often related to environmental compliance or regional production lines, without altering the functional specifications compared to the base SN74ABT273PWR model. It is designed for general-purpose digital applications requiring reliable data latching.
