SN74LVTH652PW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH652PW is an octal bus transceiver and register designed for low-voltage 3.3-V VCC operation with TTL interface capability to 5-V systems. It features independent output enable controls (OEAB, OEBA) and select-control inputs (SAB, SBA) for multiplexed data transmission between real-time buses and internal D-type flip-flops. The device supports hot insertion via Ioff and power-up 3-state circuitry, ensuring high-impedance states during power transitions. Active bus-hold circuitry maintains valid logic levels on floating inputs without external resistors. It operates within a supply voltage range of 2.7 V to 3.6 V and an ambient temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode signal operation by providing a TTL interface to 5-V system environments while operating at 3.3 V.
• Enables multiplexed transmission of data directly from the data bus or from internal storage registers using dedicated select-control inputs.
• Features active bus-hold circuitry that eliminates the need for external pullup or pulldown resistors on data inputs.
• Provides Ioff and power-up 3-state support to facilitate safe hot-insertion applications.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant against the ordering information table, as the SN74LVTH652 series includes multiple packages such as SOIC, SSOP, and TVSOP. Confirm that the PW suffix corresponds to the TSSOP package type required for your design. Ensure compatibility with the specified operating temperature range and voltage parameters before finalizing procurement decisions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring octal bidirectional data transfer with integrated storage capabilities. It is suitable for applications needing independent control over data flow direction and storage selection. Consider its mixed-mode voltage tolerance if interfacing with legacy 5-V components. Verify that the TSSOP-24 package dimensions fit the available PCB space and thermal requirements.
