SN74ALS245ADBR

Overview

The SN74ALS245ADBR is an octal bus transceiver manufactured by Texas Instruments, belonging to the 74ALS logic series. It features a single element with eight bits per element and provides three-state outputs. The device operates within a supply voltage range of 4.5V to 5.5V and supports surface mount installation in a 20-SOIC package with a width of 5.30mm. It functions as a non-inverting transceiver and maintains an operating temperature range from 0°C to 70°C.

Feature Summary

• Provides bidirectional data transmission via an octal bus architecture
• Features three-state outputs for effective bus line management
• Operates as a non-inverting transceiver within the 74ALS logic family

Applications

• Memory mapping control circuits
• Clock drivers
• Bus-oriented transmissions

Procurement Notes

Verify the specific suffix 'DBR' against the manufacturer's official documentation to confirm the tape and reel packaging configuration and ensure compliance with RoHS3 standards. Confirm that the 20-SOIC package dimensions match the design requirements before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring high-speed octal data transfer using the 74ALS logic standard. Ensure the application environment stays within the specified 0°C to 70°C temperature range and utilizes a 5V power supply compatible with the 4.5V to 5.5V operational limits.

Part Context

This part belongs to the Texas Instruments 74ALS series, which offers faster switching speeds compared to standard LS logic while maintaining similar power consumption characteristics. The SN74ALS245 variant specifically serves as an octal transceiver, distinguishing it from buffer or driver variants like the SN74ALS244.
