SN74LVCH16245ADGGR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCH16245ADGGR is a 16-bit (dual-octal) noninverting bus transceiver 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/output environments with 3.3-V VCC. The device provides a maximum propagation delay of 4 ns at 3.3 V and includes active bus-hold circuitry on data inputs to maintain valid logic states without external resistors. It supports partial-power-down mode via Ioff circuitry and offers ESD protection exceeding 2000 V per the human-body model.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode signal operation by accepting 5-V input voltages while operating at lower supply voltages down to 1.65 V.
• Features active bus-hold circuitry on all data inputs to eliminate the need for external pullup or pulldown resistors.
• Includes Ioff support to prevent damaging current backflow through the device during partial-power-down or live insertion scenarios.
• Provides high electrostatic discharge protection capabilities exceeding standard industry thresholds for both human-body and machine models.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant required, as the DGGR suffix denotes the TSSOP-48 package. Confirm RoHS compliance status and lead finish specifications against the latest orderable addendum. Ensure the design accounts for the recommended operating temperature range of -40°C to +125°C. Check for any recent product life cycle changes or alternative package options if availability is constrained.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing buses with different voltage levels, specifically translating between 5-V and 3.3-V domains. The wide operating voltage range allows flexibility in power supply design. Consider the 4-ns propagation delay for timing-critical applications. The dual-octal architecture permits configuration as either two 8-bit or one 16-bit transceiver based on system requirements.
