SN74ALS245A-1DB

Overview

The SN74ALS245A-1DB is an octal bus transceiver from Texas Instruments featuring three-state outputs. It 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. The device provides 15mA output high current and 24mA output low current, ensuring sufficient drive capability for standard logic loads. It functions as a non-inverting transceiver with one element handling eight bits per element.

Feature Summary

Octal bus transceiver architecture with three-state outputs
Non-inverting signal transmission functionality
High drive capability suitable for standard logic loads

Applications

Memory mapping control
Clock driving
Bus-oriented communications

Procurement Notes

Verify the specific suffix '1DB' against the official Texas Instruments datasheet to confirm the exact package type and tape-and-reel specifications. Ensure compatibility with the required operating temperature range and voltage levels before integration into the design.

Selection Notes

Select this component when an octal bidirectional data path with three-state isolation is required. The ALS series offers improved speed-power product compared to standard TTL. Confirm that the 20-SOIC package dimensions fit the PCB layout constraints and that the drive current meets the load requirements.

Part Context

This part belongs to the SN54/74ALS245(A) family of octal bus transceivers. It is designed for high-speed digital applications requiring efficient data transfer between buses. The device is manufactured by Texas Instruments and is part of their established logic IC portfolio.

Replacement Considerations

Check for SN74ALS245ANSR or SN74ALS245ADWR as potential pin-compatible alternatives. Verify electrical characteristics and package dimensions match the original design requirements before substitution.
