Product details
Overview
74AVC2T45DP-Q100 from Nexperia is a dual-bit, dual-supply voltage level translator/transceiver enabling bidirectional logic-level translation between 0.8 V and 3.6 V domains. It features two I/O ports (1A/2A referenced to VCC(A), 1B/2B to VCC(B)), DIR-controlled direction, IOFF partial power-down, and AEC-Q100 Grade 1 qualification for automotive use in infotainment and ADAS domain controllers.
For engineers reviewing the 74AVC2T45DP-Q100 datasheet, 74AVC2T45DP-Q100 pinout, 74AVC2T45DP-Q100 application, or 74AVC2T45DP-Q100 equivalent, key selection criteria include bidirectional translation latency (as low as 2.8 ns at 3.3 V), IOFF leakage (<±1 μA at 0 V supply), wide dual-rail voltage support (0.8–3.6 V per rail), and TSSOP8 package compatibility with automotive PCB layout constraints.
Technical Context
The device implements a dual-rail CMOS transceiver architecture with independent VCC(A) and VCC(B) supplies, where DIR input (referenced to VCC(A)) controls signal flow direction: HIGH enables A→B, LOW enables B→A. Both ports operate in 3-state mode during direction transitions or suspend conditions.
Suspend mode activates when either VCC(A) or VCC(B) = GND, forcing both ports into high-impedance OFF-state. IOFF circuitry ensures sub-1 μA backflow current suppression during partial power-down, meeting JEDEC JESD78 Class II latch-up immunity (>100 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V per rail - supports translation across all common low-voltage nodes (0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V) |
| Max Data Rate | 500 Mbit/s - achievable only for 1.8 V–3.3 V translation; lower rates apply for sub-1.8 V rails (e.g., 240 Mbit/s to 1.2 V) |
| Propagation Delay | 2.4 ns (min) to 9.2 ns (max) - direction- and voltage-dependent; lowest at 3.3 V → 3.3 V (2.4 ns A→B) |
| IOFF Leakage | <±1 μA at 0 V supply - prevents damaging backflow current during system power sequencing |
| ESD Protection | HBM >8 kV, CDM >1 kV - exceeds automotive robustness requirements per AEC-Q100 Grade 1 |
| Operating Temp | −40 °C to +125 °C - qualified for under-hood and cockpit electronics without derating |
| Power Dissipation | 250 mW max (TSSOP8) - linearly derated above 96 °C at 4.6 mW/K |
Pinout & Package
TSSOP8 package (SOT505-2): plastic thin shrink small outline, 8 leads, 3 mm body width, 0.5 mm lead length, pin 1 indicator below marking code 'B45' in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC(A) | Supply for A-side I/O and DIR input - sets voltage reference and logic thresholds for pins 1A, 2A, DIR |
| 2 | 1A | Data I/O port A channel 1 - bidirectional, referenced to VCC(A); driven by or drives A-side logic |
| 3 | 2A | Data I/O port A channel 2 - identical function to 1A, electrically isolated |
| 4 | GND | Common ground reference - mandatory for noise control and ESD path integrity |
| 5 | DIR | Direction control input - HIGH enables 1A↔1B/2A↔2B data flow A→B; LOW enables B→A |
| 6 | 2B | Data I/O port B channel 2 - bidirectional, referenced to VCC(B); interfaces with B-side logic domain |
| 7 | 1B | Data I/O port B channel 1 - identical function to 2B, electrically isolated |
| 8 | VCC(B) | Supply for B-side I/O - sets voltage reference and logic thresholds for pins 1B, 2B |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive operation from −40 °C to +125 °C with full reliability testing |
| Dual-rail independent supply | VCC(A) and VCC(B) can be set to different voltages simultaneously (e.g., 1.8 V ↔ 3.3 V) |
| IOFF partial power-down | Disables outputs and blocks backflow current when either VCC rail is at 0 V |
| Suspend mode | Automatic high-Z state on both ports if VCC(A) = GND or VCC(B) = GND - eliminates bus contention risk |
| JEDEC compliance | Fully compliant with JESD8-12 through JESD8-B standards across all supported voltage ranges |
Applications
| Infotainment SoC Interface | ADAS Camera Sensor Link |
|---|---|
Use Scenario: Connecting a 1.2 V MIPI D-PHY transmitter in an infotainment SoC to a 1.8 V display timing controller. IC Role / Device Role / Timing Role: Bidirectional level translator enabling clock/data co-translation with sub-3 ns propagation delay and simultaneous voltage domain isolation. Use Value: Eliminates need for separate unidirectional translators and reduces PCB area by 40% versus discrete solutions while maintaining MIPI signal integrity. | Use Scenario: Interfacing a 3.3 V automotive camera sensor output to a 1.5 V image signal processor (ISP) input in a surround-view system. IC Role / Device Role / Timing Role: Unidirectional level shifter (DIR = LOW) translating parallel pixel data with <5 ns skew between channels. Use Value: Enables direct sensor-to-ISP connection without external pull-ups or level-shifting FETs, reducing BOM count and EMI susceptibility. |
| Body Control Module Bus Bridge | Telematics Gateway UART Isolation |
Use Scenario: Bridging LIN-compatible 12 V microcontroller GPIO (via level-shifted 5 V buffer) to a 3.3 V CAN transceiver interface MCU. IC Role / Device Role / Timing Role: Dual-channel translator supporting asynchronous GPIO handshaking with IOFF protection during module sleep states. Use Value: Prevents backfeed current during LIN bus sleep mode, extending battery life and eliminating need for external blocking diodes. | Use Scenario: Isolating UART signals between a 1.8 V cellular modem and a 2.5 V telematics host MCU in a V2X gateway. IC Role / Device Role / Timing Role: Bidirectional translator operating in auto-direction-sensing configuration with pull-up resistors on both sides. Use Value: Maintains UART frame timing integrity (no added jitter) while enabling mixed-voltage debug access and firmware updates over same physical lines. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply voltage translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AVC2T45RSWR | Same dual-rail architecture but rated only to +85 °C; no AEC-Q100 qualification; VSSOP8 package (SOT765-1) | Not suitable for under-hood or safety-critical modules requiring Grade 1 temperature range | Select only for non-automotive industrial or consumer applications with ambient ≤85 °C |
| TXS0202DCUR | Auto-direction sensing (no DIR pin); lower max data rate (100 Mbit/s); higher propagation delay (≥10 ns); supports 1.2 V–3.6 V rails only | Lacks deterministic direction control - unsuitable for synchronous protocols like SPI or parallel buses requiring precise timing | Prefer for simple UART/I²C links where direction changes infrequently and latency is non-critical |
Compared with SN74AVC2T45RSWR and TXS0202DCUR, the 74AVC2T45DP-Q100 uniquely delivers AEC-Q100 Grade 1 compliance, sub-3 ns propagation at 3.3 V, and explicit DIR control-making it the only choice for time-critical automotive serial buses and safety-relevant domain controllers.

FAQ
What is the minimum valid voltage difference between VCC(A) and VCC(B)?
No minimum voltage difference is required: VCC(A) and VCC(B) may be equal (e.g., both 1.8 V) or differ by any amount within 0.8 V–3.6 V range. The device functions correctly with identical or maximally disparate rails, validated across all JEDEC-compliant combinations including 0.8 V ↔ 3.3 V.
Can DIR be driven from a different voltage domain than VCC(A)?
No - DIR is strictly referenced to VCC(A) and must be driven within 0 V to VCC(A). Driving DIR from VCC(B) or another rail violates absolute maximum ratings and risks latch-up or undefined behavior. External level shifting of DIR is not supported or recommended.
How does suspend mode behave when only VCC(A) is powered?
When VCC(A) = 3.3 V and VCC(B) = GND, both A and B ports enter high-impedance OFF-state immediately. No current flows through I/O pins, and inputs are ignored - this prevents bus contention and protects downstream 3.3 V logic from being back-driven by floating B-side traces.
Is the 74AVC2T45DP-Q100 compatible with 5 V tolerant inputs?
No - inputs accept voltages up to 3.6 V only. Applying 5 V to any pin (including 1A, 2A, 1B, 2B, or DIR) exceeds absolute maximum rating (VI = −0.5 V to +4.6 V) and risks permanent damage. External clamping or series resistance is required for legacy 5 V system interfacing.
