JM38510/65755B2A

Overview

The JM38510/65755B2A is a military-grade octal buffer and line driver manufactured by Texas Instruments. It implements the 54HCT244 logic family, featuring eight non-inverting channels with single-ended inputs and three-state outputs. The device operates on a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a maximum propagation delay of 45 ns at 4.5 V and 40 ns at 5.5 V under specified load conditions. It utilizes CMOS processing technology and is housed in a 20-pin ceramic dual in-line package (CDIP) designed for through-hole mounting.

Feature Summary

• Provides eight independent buffering channels with three-state output control for bus-oriented applications
• Features TTL-compatible CMOS inputs ensuring reliable interfacing with standard logic families
• Engineered for high-temperature stability and radiation hardness suitable for demanding military environments

Applications

• Military communication systems requiring robust signal buffering
• High-reliability computing architectures utilizing bus structures
• Avionics data handling units operating in extreme temperature ranges

Procurement Notes

Verify the specific suffix B2A against official Texas Instruments documentation to confirm pinout and electrical specifications match your design requirements. Ensure that the CDIP package dimensions align with your PCB footprint constraints. Confirm that the military screening grade meets your project's reliability standards before finalizing procurement orders.

Selection Notes
