SNJ54LVCH245AJ

Overview

The SNJ54LVCH245AJ is an octal bus transceiver manufactured by Texas Instruments, belonging to the LVCH logic series. It features bidirectional data transmission with three-state outputs and a single direction control pin. The device operates within a supply voltage range of 2 V to 3.6 V and supports TTL/CMOS input levels with LVTTL output levels. It is housed in a 20-CDIP package and is rated for operation across an extended temperature range from -55 °C to +125 °C.

Feature Summary

• Bidirectional octal bus transceiver architecture
• Single-direction control functionality
• Three-state output capability

Applications

• Memory mapping controllers
• Clock drivers
• Bus-oriented communications

Procurement Notes

Verify the specific suffix 'AJ' against the manufacturer's current datasheet to confirm the package type and material composition. Ensure the component meets the required environmental specifications for the intended operating temperature range. Cross-reference the ordering information with official Texas Instruments documentation to validate availability and compliance status before procurement.

Selection Notes

Select this component when designing systems requiring low-voltage operation between 2 V and 3.6 V. It is suitable for applications needing bidirectional data flow controlled by a single signal line. Consider the 20-CDIP package constraints for through-hole mounting requirements. Verify that the LVTTL output levels are compatible with the receiving logic family in the target circuit design.

Part Context

This part belongs to the SN54LVCH245A series of octal bus transceivers. It shares functional similarities with other devices in the LVCH family but is distinguished by its ceramic DIP packaging and military-grade temperature rating. The device provides a robust solution for high-density digital systems requiring reliable bidirectional data transfer over extended industrial or military temperature ranges.
