74AVC1T45GS-Q100H

Overview

The Nexperia 74AVC1T45GS-Q100H is a single-bit, dual-supply voltage level translator and transceiver with three-state outputs. It facilitates bidirectional translation between logic nodes operating at voltages ranging from 0.8 V to 3.6 V. The device includes two 1-bit input-output ports (A and B), a direction control input (DIR), and dual supply pins (VCC(A) and VCC(B)). Both supply pins support any voltage within the 0.8 V to 3.6 V range, enabling compatibility with low-voltage standards including 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V. Pins A and DIR are referenced to VCC(A), while pin B is referenced to VCC(B).

Feature Summary

• Automotive product qualification in accordance with AEC-Q100 Grade 1 standard.
• IOFF circuitry enables partial power-down mode operation by disabling outputs to prevent damaging backflow current.
• Suspend mode activates when either supply voltage is at GND level, placing both ports in a high-impedance OFF-state.
• ESD protection exceeds 8000 V for Human Body Model (HBM) class 3B and 1000 V for Charged Device Model (CDM) class C3.

Applications

• Partial power-down applications requiring isolation during power-off states.
• Bidirectional logic level-shifting between different voltage domains.
• Unidirectional logic level-shifting applications controlled via the DIR pin.
• Automotive electronic systems requiring AEC-Q100 Grade 1 qualified components.

Procurement Notes

Verify that the specific suffix 'GS' corresponds to the SOT1202 package variant as documented in the ordering information table. Confirm the temperature range requirement matches the -40 °C to +125 °C specification listed for this type number. Ensure the application design accounts for the lack of an output enable pin to avoid bus contention during direction changes in bidirectional setups.

Selection Notes

Select this component when a single-channel bidirectional translator with explicit direction control is required. The device supports wide supply voltage ranges on both ports, making it suitable for translating between various low-voltage nodes. Consider the SOT1202 package dimensions if space constraints dictate the use of an extremely thin small outline package without leads.

Part Context

This part belongs to the 74AVC1T45-Q100 family of dual-supply voltage level translators. Other variants in the family include the 74AVC1T45GW-Q100 in a TSSOP6 package and the 74AVC1T45GM-Q100 in an XSON6 package. All variants share identical electrical characteristics and functionality, differing only in the physical package outline and terminal configuration.
