Product details

Overview

74AVC2T245GU-Q100 from Nexperia is a 2-bit dual-supply translating transceiver enabling bidirectional level translation between independent voltage domains (0.8 V to 3.6 V). It supports two 1-bit or one 2-bit configuration, features DIRn and OE controls, IOFF partial power-down, and AEC-Q100 Grade 1 qualification for automotive infotainment and ADAS domain controllers.

For engineers reviewing the 74AVC2T245GU-Q100 datasheet, 74AVC2T245GU-Q100 pinout, 74AVC2T245GU-Q100 application, or 74AVC2T245GU-Q100 equivalent, key selection criteria include dual-rail voltage flexibility (VCC(A)/VCC(B) = 0.8–3.6 V), 380 Mbit/s max data rate (≥1.8 V → 3.3 V), suspend-mode isolation, and XQFN10 package thermal performance in space-constrained automotive modules.

Technical Context

This transceiver implements true bidirectional voltage translation via separate input-referenced supply rails: An, DIRn, and OE are referenced to VCC(A); Bn pins are referenced to VCC(B). Direction control is asynchronous-DIRn HIGH enables An→Bn, LOW enables Bn→An-and OE (active LOW) forces both ports into high-impedance state.

The IOFF circuit ensures robust partial power-down: when either VCC(A) or VCC(B) = GND, all I/Os enter high-Z OFF-state, blocking damaging backflow current. Suspend mode compliance meets automotive functional safety requirements for mixed-voltage subsystems during sleep/wake transitions.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Range (VCC(A)/VCC(B))	0.8 V to 3.6 V each - enables translation across 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V logic nodes without external level shifters
Max Data Rate	380 Mbit/s (≥1.8 V ↔ 3.3 V) - supports high-speed interconnects like MIPI D-PHY auxiliary channels or camera sensor interfaces
Propagation Delay (An→Bn)	0.8 ns min / 8.4 ns max (−40 °C to +125 °C, 3.0–3.6 V) - ensures timing margin for sub-1 ns clock-domain crossing in real-time control loops
IOFF Leakage Current	±5 μA max (VCC = 0 V, other rail at 3.6 V) - guarantees <10 μA total off-state current for ultra-low-power wake-on-event designs
ESD Protection	HBM >8 kV, CDM >1 kV - exceeds AEC-Q100 stress requirements for assembly and field reliability in harsh automotive environments
Operating Temperature	−40 °C to +125 °C - qualified for under-hood and cockpit applications per AEC-Q100 Grade 1
Package	XQFN10 (SOT1160-1), 1.4 × 1.8 × 0.5 mm - provides low thermal resistance (θ_JA ≈ 140 °C/W) and PCB area savings in compact ECUs

Pinout & Package

XQFN10 (SOT1160-1) plastic extremely thin quad flat package with no leads, 10 terminals, body size 1.40 × 1.80 × 0.50 mm, exposed thermal pad on underside for enhanced heat dissipation in automotive modules.

Pin/Terminal	Circuit Role	Design Meaning
1	DIR1	Direction control for first bit: HIGH = A1→B1, LOW = B1→A1; referenced to VCC(A)
2	OE	Active-LOW output enable: drives both ports to high-Z when asserted; referenced to VCC(A)
3	GND	Common ground reference for all internal circuitry and ESD protection networks
4	B2	Data I/O port B, bit 2; referenced to VCC(B); bidirectional path controlled by DIR2
5	B1	Data I/O port B, bit 1; referenced to VCC(B); bidirectional path controlled by DIR1
6	VCC(B)	Supply rail for B-side I/Os (B1, B2); sets logic thresholds and drive strength for Bn outputs
7	VCC(A)	Supply rail for A-side I/Os (A1, A2), DIRn, and OE; defines input thresholds and control logic levels
8	A1	Data I/O port A, bit 1; referenced to VCC(A); bidirectional path controlled by DIR1
9	A2	Data I/O port A, bit 2; referenced to VCC(A); bidirectional path controlled by DIR2
10	DIR2	Direction control for second bit: HIGH = A2→B2, LOW = B2→A2; referenced to VCC(A)

Key Features

Feature	Design Value
Configurable bidirectional translation	Two independent DIR inputs allow per-bit direction control-enables asymmetric protocols like I²C pull-up domain bridging without external logic
IOFF partial power-down	Automatic high-Z isolation when either VCC rail drops to GND-eliminates need for external isolation switches in battery-backed subsystems
AEC-Q100 Grade 1 qualification	Validated for −40 °C to +125 °C operation with latch-up immunity >100 mA-meets functional safety requirements for ASIL-B systems
JEDEC-compliant voltage standards	Meets JESD8-12 through JESD8-B across full 0.8–3.6 V range-ensures interoperability with legacy and next-gen low-voltage SoCs
Suspend mode behavior	Both An and Bn enter guaranteed high-impedance OFF-state if VCC(A) = GND or VCC(B) = GND-prevents bus contention during MCU reset sequences

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-supply translating transceiver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74AVC2T245RSWR	Same 2-bit dual-rail architecture but rated only to +85 °C; non-automotive grade; no AEC-Q100 qualification	Lacks suspend-mode validation and extended temperature characterization required for under-hood use	Select for cost-sensitive consumer or industrial applications where −40 °C to +125 °C operation is not required
74LVC2T45DP,125	Lower max data rate (200 Mbit/s), narrower VCC range (1.65–5.5 V), no IOFF circuit-requires external power sequencing	Cannot support 0.8 V domains or automatic isolation during partial power-down	Use only in fixed-rail 3.3 V/5 V systems with simple direction control and no automotive qualification needs

FAQ

What is the minimum valid supply voltage for VCC(A) and VCC(B) simultaneously?

The device operates with both VCC(A) and VCC(B) as low as 0.8 V concurrently. Static and dynamic specifications-including VIH/VIL thresholds, propagation delay, and drive strength-are fully characterized down to this voltage. Operation below 0.8 V is outside specification and may result in undefined logic states or increased leakage.

How does the IOFF feature behave when only VCC(A) is powered and VCC(B) is at 0 V?

When VCC(B) = 0 V and VCC(A) is active, the B-side I/Os (B1, B2) enter high-impedance OFF-state per IOFF circuitry, while A-side pins remain functional. This prevents back-current flow from A-side signals into the unpowered B domain-critical for safe hot-plug operation in modular automotive architectures.

Can DIR1 and DIR2 be tied together for synchronized 2-bit translation?

Yes-DIR1 and DIR2 may be connected to a common control line to configure both bits identically (An↔Bn simultaneously). The datasheet confirms identical electrical characteristics and timing for both DIR inputs, and no skew or contention is introduced. This simplifies PCB routing in applications requiring uniform direction control.

Is the XQFN10 package compatible with standard reflow profiles for lead-free assembly?

Yes-the SOT1160-1 (XQFN10) package is qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 1 and supports peak reflow temperatures up to 260 °C. Its 0.5 mm profile and exposed thermal pad require standard solder paste volume and stencil aperture design per Nexperia's recommended footprint guidelines.
