SN74LVT16952DLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVT16952DLR is a 3.3-V ABT 16-bit registered transceiver with 3-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 3.6 V and supports mixed-mode signal operation, allowing 5-V input and output voltages alongside 3.3-V VCC. The device features active bus-hold data inputs and distributed VCC/GND pins to minimize high-speed switching noise. It is characterized for operation from -40°C to +85°C and utilizes Advanced BiCMOS technology for low-static power dissipation.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode signal operation with 5-V I/O capability while operating at 3.3 V
• Active bus-hold circuitry eliminates the need for external pullup resistors on unused or floating data inputs
• Distributed VCC and GND pin configuration minimizes high-speed switching noise
• Flow-through architecture optimizes PCB layout

Buffers, Drivers, Receivers, Transceivers Applications

• Low-voltage (3.3-V) system environments requiring TTL interface compatibility
• Mixed-mode signal applications involving 5-V and 3.3-V systems
• Unregulated battery operation down to 2.7 V
• Live insertion support in bus architectures

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the SN74LVT16952DLR package matches the SSOP-56 specification required for your design. Confirm that the component meets the recommended operating temperature range of -40°C to +85°C for your specific application environment. Ensure that the supply voltage remains within the 2.7 V to 3.6 V limits during operation. Check for any specific handling requirements related to the Advanced BiCMOS technology used in this device.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select the SN74LVT16952DLR when a 16-bit registered transceiver is needed for 3.3-V systems with 5-V tolerance. Consider its flow-through architecture for optimized PCB layout and its ability to support live insertion. Evaluate its low-static power dissipation and ESD protection capabilities against other available options in the Widebus family.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the SN74LVT16952 series, part of Texas Instruments' Widebus family. It is designed using state-of-the-art Advanced BiCMOS (ABT) technology. The device functions as two 8-bit transceivers or one 16-bit transceiver, providing registered data storage on clock transitions. It is distinct from non-registered variants due to its internal latching capability.
