JM38510/32402B2A

Overview

The JM38510/32402B2A is an octal buffer and line driver manufactured by Texas Instruments. It features 3-state outputs and operates within a voltage range of 4.5 V to 5.5 V. The device utilizes the LS logic series and provides inverted output functionality. It is housed in a 20-LCCC package with a ceramic metal-sealed cofired body. The component supports bidirectional data transmission and is rated for operation between -55 °C and 125 °C.

Feature Summary

• Octal buffering and line driving capabilities with three-state output control
• Bidirectional data flow support for system interconnects
• Military-grade reliability with extended temperature range operation

Applications

• High-reliability military communication systems
• Avionics data bus interfaces
• Spacecraft telemetry and command subsystems

Procurement Notes

Verify the specific suffix B2A corresponds to the 20-LCCC ceramic package configuration. Confirm that the component meets all applicable MIL-PRF-38534 quality level requirements. Ensure that radiation hardness specifications align with mission constraints, as standard LS series devices may not be hardened against ionizing radiation effects without explicit documentation.

Selection Notes

Select this component when designing systems requiring octal buffering with high noise immunity and strict environmental tolerance. The 3-state outputs allow multiple drivers to share a common bus without contention. Verify that the input logic levels are compatible with the driving source within the specified 4.5 V to 5.5 V supply range.

Part Context

This part belongs to the SN54LS241 family of octal buffers. It serves as a military-grade alternative to commercial variants, offering enhanced durability and performance stability under extreme conditions. The LS series ensures compatibility with standard TTL logic families while providing improved power consumption characteristics compared to earlier S-series components.
