SN75138NS

Drivers, Receivers, Transceivers Overview

The SN75138NS is a quad bus transceiver manufactured by Texas Instruments, designed for high-speed data transmission across parallel buses. It integrates four non-inverting drivers and four receivers within a single package, facilitating bidirectional communication between two buses. The device operates with a supply voltage range of 4.75 V to 5.25 V and supports TTL input levels. Key electrical parameters include a propagation delay of 24 ns, a low-level output current capability of 100 mA, and a high-level output current of -400 uA. It functions reliably within an operating temperature range of 0°C to +70°C and utilizes a 16-pin Small Outline (SO) surface-mount package.

Drivers, Receivers, Transceivers Feature Summary

• Integrates four independent non-inverting bus transceivers for simultaneous bidirectional data transfer.
• Features open-collector outputs capable of driving significant loads with high low-level sink current.
• Supports direct interface with TTL logic inputs without requiring external level shifting components.

Drivers, Receivers, Transceivers Applications

• High-speed parallel bus systems requiring reliable data direction control.
• Industrial control networks utilizing standard TTL-compatible signaling protocols.
• Memory buffer interfaces in computing architectures needing fast signal propagation.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'NS' against the manufacturer's official datasheet to confirm the exact package variant and temperature grade. Ensure compatibility with existing PCB footprints for the 16-SO form factor. Cross-reference ordering information directly with Texas Instruments or authorized distributors to validate current production status and availability constraints.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require multiple independent bidirectional data paths on a single chip. Consider the 100 mA low-level output drive strength for applications interfacing with heavy capacitive loads. Verify that the 0°C to +70°C commercial temperature range meets the environmental requirements of the target deployment scenario.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SN75138 family of quad bus transceivers from Texas Instruments. It shares functional similarities with other devices in the series but differs in packaging and specific electrical characteristics. The 'N' suffix typically denotes a plastic DIP package in some contexts, while 'S' indicates SOIC; however, the combined 'NS' designation specifically identifies the surface-mount SOIC variant as documented in distributor specifications.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes may include other quad bus transceivers from the same family, such as the SN75138DR or SN75138PW, provided they match the required package type and electrical specifications. Always verify pinout compatibility and thermal performance before implementing any alternative component in an existing design.
