JM38510/32803B2A

Overview

The Texas Instruments JM38510/32803B2A is a military-grade octal bus transceiver utilizing Schottky transistor logic. It features 20 pins in an LCCC package and supports bidirectional data transmission between A and B buses controlled by the DIR input. The device provides three-state outputs with active-low enable (OE) for bus isolation. It operates within a supply voltage range of 4.5 V to 5.5 V and withstands temperatures from -55 °C to 125 °C.

Feature Summary

Bidirectional data transfer capability between two eight-bit buses
Three-state outputs allowing direct bus line driving and high-impedance isolation
Built-in hysteresis on bus inputs to enhance noise margins
PNP input structure designed to reduce DC loading on bus lines

Applications

Building automation systems
Electronic point of sale terminals
Factory automation and control networks
Test and measurement equipment

Procurement Notes

Verify that the component conforms to MIL-PRF-38535 specifications, as parameters are fully tested under this standard. Confirm the specific ordering suffix matches the required package type and material finish. Ensure compliance with environmental directives such as RoHS if applicable to the specific manufacturing lot.

Selection Notes

Select this component when a ruggedized, wide-temperature octal transceiver is required for military or aerospace applications. Compare drive strength requirements against the SN54LS245 specifications. Consider the LCCC package constraints for PCB layout and thermal management during system design.

Part Context

This part belongs to the SNx4LS245 family of octal bus transceivers manufactured by Texas Instruments. It serves as the military-grade equivalent to commercial variants, offering extended temperature ranges and reliability standards suitable for harsh environments while maintaining functional compatibility with standard '245 logic functions.
