74LVC16245ADGVRE4

Overview

The SN74LVC16245A is a 16-bit bus transceiver with 3-state outputs designed for asynchronous communication between data buses. It operates from a supply voltage of 1.65 V to 3.6 V and features inputs that accept voltages up to 5.5 V, supporting mixed-mode signal operation in 5-V input/3.3-V VCC environments. The device provides a maximum propagation delay of 4 ns at 3.3 V and includes Ioff circuitry to support live insertion and partial-power-down modes.

Feature Summary

• Supports mixed-mode signal operation allowing 5-V tolerant inputs with 3.3-V VCC
• Ioff feature prevents damaging current backflow during power-down or live insertion
• Configurable as two 8-bit transceivers or one 16-bit transceiver

Applications

• Wireless and Telecom Infrastructures
• Wearable Health and Fitness Devices

Procurement Notes

Verify the specific package variant (DGV TVSOP-48) against the design requirements. Confirm RoHS compliance and lead finish specifications using the official Package Option Addendum. Ensure ESD handling protocols are followed due to limited built-in protection. Cross-reference the ordering suffix with the manufacturer's documentation to confirm availability status.

Selection Notes

Select this component when interfacing 16-bit buses requiring mixed-voltage translation between 3.3-V and 5-V domains. The wide operating voltage range accommodates low-power applications down to 1.65 V. Verify that the 5.5-V input tolerance meets the source logic levels. Consider the thermal resistance characteristics if operating near the upper temperature limits.
