Procurement Notes
Verify the specific datasheet version provided by Texas Instruments for the SN74ALS38245ADBR to confirm electrical characteristics and pin configurations. Ensure that the ordering suffix matches the required package type and temperature range. Cross-reference the manufacturer's part number with authorized distributors to avoid counterfeit components. Check for any recent product change notifications regarding manufacturing site or material composition updates before finalizing procurement orders.
Selection Notes
Select this component when designing circuits that require bidirectional data transfer between buses with high speed and low power constraints. The ALS series offers a balance between performance and power dissipation compared to standard TTL or other logic families. Consider the 20-SSOP package dimensions for PCB layout compatibility. Evaluate the operating voltage range against the system's power supply stability to ensure reliable logic level interpretation during operation.
Part Context
This part is part of Texas Instruments' extensive portfolio of logic integrated circuits. The ALS family is known for its improved speed and power efficiency over earlier generations. The SN74ALS38245ADBR specifically addresses needs for multi-bit data routing in complex digital systems. Its design aligns with industry standards for compatibility with other logic devices in mixed-signal environments.
Replacement Considerations
Consult official substitution guides from Texas Instruments for compatible alternatives. Verify pin-to-pin compatibility and electrical parameter equivalence before replacing the component. Ensure that any substitute part maintains the same logic family characteristics and package outline to fit existing PCB footprints without modification.
