Overview
The SNJ54AHCT541J is an octal buffer and line driver featuring three-state outputs, manufactured by Texas Instruments. It utilizes AHCT technology to provide TTL-voltage compatible inputs while operating on a CMOS core. The device is housed in a 20-pin ceramic dual in-line package (CDIP). It operates within a supply voltage range of 4.5 V to 5.5 V and supports an extended military-grade temperature range from -55°C to 125°C. The component includes two active-low output enable inputs for bus-oriented control.
Feature Summary
- Features TTL-voltage compatible inputs for direct interfacing with TTL logic systems.
- Provides high electrostatic discharge protection exceeding specified JESD standards.
- Includes dual output enable inputs to facilitate independent control of data flow direction.
Applications
- Driving bus lines in digital communication architectures
- Buffering memory address registers
- Military and defense electronic systems
Procurement Notes
Verify the specific ordering suffix 'J' corresponds to the CDIP package configuration. Confirm that the procurement channel sources parts compliant with MIL-PRF-38535 if full parameter testing is required, as production processing may not include all tests otherwise. Ensure the supplier provides documentation verifying the military grade status and RoHS exemption details.
Selection Notes
Select this component when a wide operating temperature range and robust ESD protection are necessary for military applications. The AHCT input compatibility allows seamless integration with existing TTL-based designs without requiring level shifting. Verify that the 20-pin CDIP footprint matches the target printed circuit board layout constraints.
Part Context
This part belongs to the SN54/74AHCT541 family of octal buffers/drivers. The 'SNJ' prefix indicates a military-grade device produced under quality assurance standards suitable for defense applications. It shares functional characteristics with commercial variants but adheres to stricter environmental and reliability specifications defined for the military sector.
Replacement Considerations
Direct replacements include other SN54AHCT541 variants with different package options such as LCCC or CFP. Commercial equivalents like SN74AHCT541 offer similar functionality but lack the extended temperature range and military certification required for this specific application.
