Flip Flops datasheet and documents for SN74ALS273DB

SN74ALS273DB

Flip Flops Overview

The SN74ALS273DB is an octal D-type flip-flop from the Texas Instruments ALS logic family, housed in a SOIC-20 surface-mount package. It features positive-edge triggering and includes a master reset (clear) function. The device operates within a supply voltage range of 4.5V to 5.5V. Key electrical parameters include a propagation delay of 15 ns, a low-level output current of 24 mA, and a high-level output current of -2.6 mA. It supports TTL input and output types.

Flip Flops Feature Summary

Octal configuration with individual data inputs for each flip-flop stage
Positive-edge triggering mechanism synchronized by clock signal
Master reset functionality to clear all outputs simultaneously

Flip Flops Applications

Buffer and storage registers
Shift registers
Pattern generators

Flip Flops Procurement Notes

Verify that the specific part number suffix 'DB' corresponds to the SOIC-20 surface-mount package variant rather than other packaging options like DIP or TSSOP. Confirm RoHS compliance status and ensure the operating temperature range meets system requirements. Cross-reference manufacturer documentation to validate pinout compatibility with existing PCB layouts before procurement.

Flip Flops Selection Notes

Select this component when designing systems requiring octal data storage with fast switching speeds provided by the ALS series. Ensure the design accommodates the specified 4.5V to 5.5V power supply constraints. Consider the thermal performance of the SOIC-20 package if high ambient temperatures are expected. Verify that the 24 mA sink capability aligns with downstream load requirements.

Flip Flops Part Context

This device belongs to the SN74ALS273 family of octal D-type flip-flops. It is part of the Advanced Low-power Schottky (ALS) logic series, which offers improved speed and power consumption compared to standard TTL. The DB suffix indicates a specific plastic small-outline integrated circuit package suitable for automated surface-mount assembly processes.
