Product details
Overview
74ALVC164245DGG-QJ from Nexperia is a 16-bit dual-supply translating transceiver with non-inverting 3-state bus-compatible outputs, designed for bidirectional level translation between 3 V (VCC(A): 1.5–3.6 V) and 5 V (VCC(B): 1.5–5.5 V) buses. It features two independent 8-bit channels (1A/1B and 2A/2B), direction control (1DIR/2DIR), output enable (1OE/2OE), and automotive-grade AEC-Q100 Grade 1 qualification (−40 °C to +125 °C). Used in mixed-voltage automotive infotainment backplanes.
For engineers reviewing the 74ALVC164245DGG-QJ datasheet, 74ALVC164245DGG-QJ pinout, 74ALVC164245DGG-QJ application, or 74ALVC164245DGG-QJ equivalent, this page delivers verified electrical parameters, TSSOP48 package mapping, functional timing behavior, and automotive-grade interface design guidance - all grounded in Nexperia's Rev. 6 (24 April 2024) product data sheet.
Technical Context
This device implements dual-rail CMOS logic with separate VCC(A) and VCC(B) supplies, enabling true bidirectional voltage translation without external biasing. Each channel uses independent DIR and OE controls to manage data flow direction and 3-state output enable, with inputs referenced to their respective supply domains (nAn/nOE/nDIR → VCC(A); nBn → VCC(B)).
The IOFF circuitry ensures partial power-down operation: when either VCC is 0 V, outputs enter high-impedance state and no current flows between rails. Suspend-mode operation requires nAn outputs set to 3-state and A-bus voltage held below 0.7 V, with VCC(B) ≥ VCC(A) under active conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | VCC(A): 1.5 V–3.6 V (3 V port); VCC(B): 1.5 V–5.5 V (5 V port); supports mixed 3 V/5 V system interfacing |
| Propagation Delay | 1.0–7.5 ns (typ. 2.5–4.9 ns), depending on supply pair and direction; enables >100 MHz bus operation at 3.3 V/5 V |
| IOFF Protection | Active when VCC(A) = 0 V or VCC(B) = 0 V; prevents cross-rail current leakage during partial power-down |

| Input Voltage Tolerance | Inputs tolerant to 5.5 V regardless of VCC(A) setting; allows direct TTL-level signal acceptance on 3 V side |
Pinout & Package
TSSOP48 package (SOT362-1), 48-pin plastic thin shrink small outline, 6.1 mm body width, 0.5 mm pitch, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR (Pins 1, 24) | Direction control input | Active-HIGH enables A→B data flow; active-LOW enables B→A; referenced to VCC(A) |
| 1OE, 2OE (Pins 48, 25) | Output enable input | Active-LOW disables both A and B ports into high-impedance state; referenced to VCC(A) |
| 1A0–1A7, 2A0–2A7 (Pins 37–47, 26–36) | A-side I/O terminals | 3 V domain data ports; referenced to VCC(A); tolerate up to 5.5 V inputs |
| 1B0–1B7, 2B0–2B7 (Pins 2–12, 13–23) | B-side I/O terminals | 5 V domain data ports; referenced to VCC(B); support TTL-level compatibility |
| VCC(A) (Pins 31, 42) | 3 V supply rail | Power source for A-side logic, DIR, and OE inputs; range: 1.5–3.6 V |
| VCC(B) (Pins 7, 18) | 5 V supply rail | Power source for B-side logic and outputs; range: 1.5–5.5 V; must be ≥ VCC(A) in active mode |
| GND (Pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Common 0 V return for both supply domains; eight dedicated pins minimize ground bounce |
Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| SN74AVC16T245RJR | TI part; same 16-bit dual-rail architecture but rated only to +85 °C; lacks AEC-Q100 qualification | Not suitable for under-hood or cockpit modules requiring Grade 1 temperature range | Select only for industrial or consumer applications where −40 °C to +85 °C suffices and automotive qualification is unnecessary |
| 74LVC16T245PWJ | Nexperia part; identical pinout and function but rated to +125 °C without AEC-Q100 stress testing | Meets extended temperature but not automotive reliability standards (e.g., HTOL, ESD retest, packaging validation) | Use where automotive qualification is not mandated but high-temp operation is required; lower cost than Q100 variant |
Compared with SN74AVC16T245RJR and 74LVC16T245PWJ, the 74ALVC164245DGG-QJ uniquely combines AEC-Q100 Grade 1 qualification, full −40 °C to +125 °C operation, and IOFF-enabled partial power-down - making it the sole choice for safety-critical automotive subsystems demanding validated long-term reliability.

FAQ
Can 74ALVC164245DGG-QJ operate with VCC(A) = 2.5 V and VCC(B) = 5.0 V?
Yes. The device supports VCC(A) from 1.5 V to 3.6 V and VCC(B) from 1.5 V to 5.5 V, with VCC(B) ≥ VCC(A) required in active mode. At 2.5 V/5.0 V, propagation delay is 1.5–9.5 ns (depending on direction), VIH/VIL thresholds remain valid, and drive strength is maintained at ±18 mA (B-side) and ±12 mA (A-side).
What happens if VCC(A) = 0 V while VCC(B) = 5 V is active?
In suspend mode, IOFF circuitry forces all A-side outputs into high-impedance and blocks current flow from VCC(B) to the A-bus - provided A-side pins are held ≤ 0.7 V. This prevents damage and unintended logic states, enabling safe partial power-down in battery-disconnected scenarios.
Is the pinout compatible with standard 74LVC16245 devices?
No. While functionally similar, the 74ALVC164245DGG-QJ uses a dedicated TSSOP48 (SOT362-1) pinout with dual VCC/GND pairs and split A/B I/O banks. Standard 74LVC16245 uses 48-pin TSSOP but with different pin assignments (e.g., VCC only on one side, merged I/O groups), making it not pin-compatible.
Does this device support hot insertion in live 5 V backplanes?
Yes. Its overvoltage-tolerant A-side inputs (rated to 5.5 V) and IOFF protection allow safe connection to an energized 5 V bus while VCC(A) is ramping. However, A-bus signals must remain ≤ 0.7 V until VCC(A) stabilizes above 1.5 V to prevent latch-up per datasheet Section 1.
