SN65HVD11QPG4

Drivers, Receivers, Transceivers Overview

The SN65HVD11QPG4 is a 3.3V half-duplex RS-485 transceiver manufactured by Texas Instruments, belonging to the SN65HVD11 series. It integrates one driver and one receiver in an 8-pin TSSOP package. The device supports data rates up to 10 Mb/s with a supply voltage range of 3.0 V to 3.6 V. It features a shutdown mode that reduces operating supply current to less than 1 µA. The component provides 16 kV IEC human-body model ESD protection and operates within a temperature range of -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• High-speed differential communication capability for RS-485 networks
• Integrated thermal shutdown and receiver fail-safe mechanisms
• Low-power operation with dedicated shutdown control pin
• Robust electrostatic discharge protection for industrial environments

Drivers, Receivers, Transceivers Applications

• Industrial automation and control systems
• Building automation and security networks
• Data acquisition and measurement equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix PG4 indicates lead-free composition and RoHS compliance as per manufacturer standards. Confirm the package type matches the design requirements, as QP denotes a TSSOP form factor. Check current lifecycle status, as availability may vary based on production schedules and obsolescence notices from Texas Instruments.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a 3.3V supply is required for RS-485 interfaces with high noise immunity needs. Ensure the application demands half-duplex communication at speeds up to 10 Mb/s. Verify that the TSSOP-8 package fits the PCB layout constraints and that the extended temperature range meets environmental specifications.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SN65HVD11 family of low-power RS-485 transceivers. It shares functional similarities with other members like the SN65HVD11DG4 but differs in package style. The QP suffix specifically identifies the Thin-Shrink Small-Outline Package (TSSOP), offering a smaller footprint compared to standard SOIC variants within the same electrical specification set.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include SN65HVD11DRG4 and SN65HVD11DGRG4, which share identical electrical characteristics but utilize SOIC packages. Cross-package replacements require careful review of pin compatibility and thermal performance differences between TSSOP and SOIC footprints.
