74AVC16T245BQ,518

Buffers, Drivers, Receivers, Transceivers Overview

The 74AVC16T245BQ,518 is a 16-bit dual supply translating transceiver with configurable voltage translation and 3-state outputs. It supports two 8-bit input-output ports (nAn and nBn) each with its own output enable (nOE) and send/receive (nDIR) input for direction control. VCC(A) and VCC(B) can be independently supplied at any voltage between 0.8 V and 3.6 V. The device complies with JEDEC standards including JESD8-12, JESD8-11, JESD8-7, JESD8-5, and JESD8-B. ESD protection exceeds 8000 V (HBM), 200 V (MM), and 1000 V (CDM). Maximum data rates reach 380 Mbit/s for translations from ≥ 1.8 V to 3.3 V. Latch-up performance exceeds 100 mA per JESD 78 Class II. Inputs accept voltages up to 3.6 V. IOFF circuitry provides partial power-down mode operation. Specified from −40 °C to +125 °C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package variant, as the base part number covers multiple packages. Confirm the temperature range specification aligns with the intended operational environment. Ensure the selected component meets the necessary JEDEC compliance standards for the target application voltage nodes. Cross-reference the datasheet revision to confirm all electrical characteristics match the design requirements.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring translation between widely varying low-voltage domains without external level shifters. Consider the HXQFN60U package constraints regarding thermal dissipation and board space. Evaluate the propagation delay characteristics against the maximum clock speeds of the connected devices. Verify that the input voltage tolerance of 3.6 V accommodates the highest voltage present on the bus lines.

Buffers, Drivers, Receivers, Transceivers Part Context
