74AVC4T774PWJ

Overview

The 74AVC4T774PW is a 4-bit dual supply translating transceiver with 3-state outputs, housed in a TSSOP16 package (SOT403-1). It supports bidirectional level translation between voltage nodes ranging from 0.8 V to 3.6 V on both VCC(A) and VCC(B) rails. The device features four independent direction control inputs (DIRn) and an active LOW output enable input (OE). It complies with JEDEC standards for supply voltages including JESD8-12 through JESD8-B. Maximum data rates vary by translation range, reaching up to 380 Mbit/s for 1.8 V to 3.3 V translations. The component operates within temperature ranges of -40 °C to +85 °C and -40 °C to +125 °C.

Feature Summary

• Bidirectional level translation between multiple low-voltage supply nodes
• Independent per-bit direction control via DIR inputs
• IOFF circuitry enables partial power-down mode without damaging backflow current
• High ESD protection exceeding 8000 V HBM and 1500 V CDM

Applications

• Connecting digital components operating at different supply voltages
• Partial power-down applications requiring bus isolation
• Systems requiring individual bit direction control
• Interfaces between 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V logic domains

Procurement Notes

Verify the specific ordering suffix matches the required temperature range and package variant. Confirm that the pinout corresponds to the SOT403-1 (TSSOP16) outline. Ensure design compatibility with the specified absolute maximum ratings for supply voltages and clamping currents. Check datasheet revisions for any updates to ESD specifications or package dimensions.

Selection Notes

Select this component when independent direction control for each of the four bits is required. It is suitable for interfaces where supply voltages on both sides may differ significantly, such as translating between 0.8 V and 3.3 V. Consider the IOFF feature if the system requires safe operation during partial power-down states. Verify that the required data rate falls within the limits defined by the specific voltage translation pair being used.

Part Context

This device belongs to the Nexperia 74AVC series of translating transceivers. It provides a solution for interfacing logic families with varying supply voltages. The 4-bit configuration allows for parallel data transfer with granular control over transmission direction. The dual-supply architecture ensures robust signal integrity across wide voltage differences.
