Product details
Overview
74AVC4T245BQ-Q100 from Nexperia is a 4-bit dual-supply translating transceiver enabling bidirectional level translation between independent voltage domains (VCC(A) and VCC(B), each 0.8 V to 3.6 V). It operates as two 2-bit or one 4-bit transceiver, with direction control (nDIR), output enable (nOE), and IOFF circuitry for partial power-down. Used in automotive infotainment domain controllers interfacing 1.2 V SoC cores with 3.3 V sensor buses.
For engineers reviewing the 74AVC4T245BQ-Q100 datasheet, 74AVC4T245BQ-Q100 pinout, 74AVC4T245BQ-Q100 application, or 74AVC4T245BQ-Q100 equivalent, key selection criteria include configurable voltage translation range, AEC-Q100 Grade 1 qualification, suspend-mode isolation, maximum data rate (380 Mbit/s at ≥1.8 V→3.3 V), and DHVQFN16 package thermal performance.
Technical Context
This device implements dual-rail I/O architecture with separate VCC(A) and VCC(B) supplies, where nAn/nDIR/nOE inputs reference VCC(A) and nBn inputs reference VCC(B). Direction control is synchronous: HIGH on nDIR enables A→B transmission; LOW enables B→A transmission.
IOFF circuitry actively disables outputs during power-down (e.g., VCC(A) = GND, VCC(B) = 3.6 V), preventing backflow current and enforcing high-impedance OFF-state on both ports. Suspend mode activates when either supply drops to GND, isolating buses without external control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | VCC(A): 0.8 V–3.6 V; VCC(B): 0.8 V–3.6 V - supports translation across 0.8/1.2/1.5/1.8/2.5/3.3 V nodes |
| Max Data Rate | 380 Mbit/s - achievable only for ≥1.8 V to 3.3 V translation; lower rates apply for sub-1.8 V interfaces |
| Propagation Delay | nAn→nBn: 0.1–9.1 ns (–40 °C to +125 °C); delay varies with supply pair and direction |
| IOFF Leakage | ±5 μA max (–40 °C to +125 °C) - ensures safe bus isolation during partial power-down |
| ESD Protection | HBM >8 kV; CDM >1 kV - meets automotive robustness requirements per AEC-Q100 |
| Operating Temp | –40 °C to +125 °C - qualified for engine bay and ADAS ECU environments |
| Package | DHVQFN16 (SOT763-1), 2.5 × 3.5 × 0.85 mm - side-wettable flanks enable AOI of solder joints |
Pinout & Package
DHVQFN16 package (SOT763-1) with 16 terminals, 2.5 mm × 3.5 mm body, 0.85 mm height, and side-wettable flanks for automated optical inspection. Exposed thermal pad (GND-connected) enhances thermal dissipation in automotive PCB layouts.

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 |
|---|---|---|---|
| SN74AVC4T245QPWRQ1 | TI part; same 4-bit dual-supply function but TSSOP16 (SOT403-1) package; higher max ICC (120 mA vs 100 mA) | Less suitable for space-constrained automotive modules due to larger footprint and no side-wettable flanks | Select when existing PCB uses TSSOP land pattern or requires marginally higher supply current headroom |
| 74LVC4T245PW-Q100 | Nexperia LVC variant; identical pinout but narrower VCC range (1.65 V–3.6 V); no 0.8 V support | Cannot translate below 1.65 V-unsuitable for ultra-low-voltage sensor interfaces or advanced SoCs | Select only for 1.8 V/2.5 V/3.3 V-only systems where cost is prioritized over voltage flexibility |

FAQ
What is the minimum valid supply voltage for reliable operation of 74AVC4T245BQ-Q100?
The device is fully specified from 0.8 V to 3.6 V on both VCC(A) and VCC(B). At 0.8 V, static parameters (VIH/VIL, VOH/VOL) and dynamic performance (tpd ≤ 14.5 ns, 380 Mbit/s not supported) remain guaranteed across –40 °C to +125 °C. Operation below 0.8 V is not characterized.
How does suspend mode behave when only VCC(A) is powered?
When VCC(A) = 3.6 V and VCC(B) = GND, the device enters suspend mode: all nAn and nBn pins go high-impedance, nDIR/nOE inputs are ignored, and IOFF limits leakage to ±5 μA. This isolates the A-bus from the unpowered B-bus without external intervention.
Can 74AVC4T245BQ-Q100 translate between 1.2 V and 3.3 V in both directions simultaneously?
No. The nDIR pin controls direction per 2-bit port: one port can be A→B while the other is B→A, but each port operates unidirectionally at any instant. Simultaneous bidirectional flow requires two separate transceivers or time-multiplexed control.
Is the exposed thermal pad on the DHVQFN16 package required to be soldered to ground?
The exposed pad (terminal 1 index area) has no electrical requirement to be soldered. If soldered, it must remain floating or connect to GND. Most automotive designs connect it to GND for improved thermal performance and EMI suppression, but functionality is preserved without connection.
