Product details
Overview
74ALVC164245DGG:11 from Nexperia is a 16-bit dual-supply translating transceiver in TSSOP48 package, enabling bidirectional level translation between 3 V (VCC(A) = 1.5–3.6 V) and 5 V (VCC(B) = 1.5–5.5 V) buses with non-inverting 3-state outputs. It supports two independent 8-bit channels (1A/1B and 2A/2B), features IOFF partial power-down, and operates across –40 °C to +125 °C for mixed-voltage industrial bus interfacing.
For engineers reviewing the 74ALVC164245DGG:11 datasheet, 74ALVC164245DGG:11 pinout, 74ALVC164245DGG:11 application, or 74ALVC164245DGG:11 equivalent, this device is selected for high-speed bidirectional voltage translation in legacy 5 V ↔ modern 3.3 V system interconnects where bus isolation, low static current (<80 μA), and suspend-mode safety are required.
Technical Context
This transceiver implements dual independent octal channels, each with separate direction (nDIR) and output enable (nOE) controls referenced to their respective supply domains (VCC(A) for A-side, VCC(B) for B-side). Data flow is strictly controlled by active-HIGH nDIR: HIGH enables A→B, LOW enables B→A.
The IOFF circuit ensures high-impedance outputs when either VCC(A) or VCC(B) = 0 V, preventing back-drive current during power sequencing. Input clamping tolerates up to 5.5 V on all pins regardless of supply, enabling safe interfacing with 5 V TTL signals even when VCC(A) is at 1.8 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | VCC(A): 1.5 V to 3.6 V (3 V bus); VCC(B): 1.5 V to 5.5 V (5 V bus) - enables direct interface between 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains |
| Propagation Delay | 1.0 ns (min) to 7.5 ns (max) - supports >100 MHz data rates in high-speed bus bridging applications |
| Output Drive Strength | ±24 mA (sink/source) at VCC = 3.0–5.5 V - sufficient to drive 50 pF loads with clean edges in dense PCB layouts |
| IOFF Current | < ±0.1 μA when VCC = 0 V - prevents leakage-induced bus contention during hot-swap or partial power-down |
| ESD Protection | HBM >2000 V, CDM >1000 V - meets industrial IEC 61000-4-2 immunity requirements without external protection |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive modules and industrial control cabinets |
| Power Dissipation | 500 mW max (TSSOP48, derated above 109 °C) - supports continuous operation in thermally constrained enclosures |
Pinout & Package
TSSOP48 (SOT362-1) package: plastic thin shrink small outline, 48 leads, body width 6.1 mm, 0.5 mm pitch, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input | Active-HIGH signal selecting A→B (HIGH) or B→A (LOW); referenced to VCC(A) |
| 1OE, 2OE | Output enable input | Active-LOW control disabling both A and B ports into high-impedance state; referenced to VCC(A) |
| 1A0–1A7, 2A0–2A7 | A-side data I/O | 8-bit parallel interface for 3 V domain; voltage range 0–VCC(A); overvoltage tolerant to 5.5 V |
| 1B0–1B7, 2B0–2B7 | B-side data I/O | 8-bit parallel interface for 5 V domain; voltage range 0–VCC(B); overvoltage tolerant to 5.5 V |
| VCC(A), VCC(B) | Supply inputs | VCC(A) powers A-side logic and I/O; VCC(B) powers B-side logic and I/O; VCC(B) ≥ VCC(A) except in suspend mode |
| GND (Pins 4,10,15,21,28,34,39,45) | Ground reference | Eight dedicated ground pins minimize ground bounce and improve noise immunity in high-speed switching |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 8-bit channels | Enables concurrent translation of two separate 8-bit buses (e.g., address + data) without cross-talk or shared control timing constraints |
| IOFF partial power-down | Guarantees high-impedance outputs when either VCC is unpowered, eliminating risk of current backflow in asymmetric power-up sequences |
| Overvoltage-tolerant inputs | All pins withstand 5.5 V regardless of VCC(A) setting - allows safe connection to 5 V TTL while operating A-side at 1.8 V |
| Wide temperature range | Specified from –40 °C to +125 °C - supports deployment in engine control units, motor drives, and outdoor telecom infrastructure |
| JEDEC-compliant voltage standards | Fully compliant with JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.7 V), and JESD8C (2.7–3.6 V) - ensures interoperability across multiple logic families |

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 |
|---|---|---|---|
| SN74AVC164245DGGR | TI part with identical pinout and function but higher ICC (120 μA vs 80 μA) and narrower VCC(A) range (1.65–3.6 V) | Not suitable for 1.5 V A-side operation; requires tighter supply regulation | Select if TI ecosystem alignment or existing footprint reuse is prioritized over ultra-low-power operation |
| 74LVC164245ADGG | Nexperia LVC variant lacks IOFF and has lower VCC(B) max (3.6 V); no suspend-mode protection | Cannot safely interface 5 V peripherals when A-side is unpowered; limited to 3.3 V↔3.3 V or 3.3 V↔2.5 V use | Choose only for cost-sensitive 3 V-only systems where 5 V tolerance and power sequencing safety are unnecessary |
Compared with SN74AVC164245DGGR and 74LVC164245ADGG, the 74ALVC164245DGG:11 uniquely supports 1.5 V A-side operation and robust IOFF protection-critical for battery-backed subsystems and hot-plug-capable industrial backplanes where supply sequencing is uncontrolled.

FAQ
Can 74ALVC164245DGG:11 operate with VCC(A) = 1.8 V and VCC(B) = 5.0 V simultaneously?
Yes. The device is explicitly rated for VCC(A) = 1.5 V to 3.6 V and VCC(B) = 1.5 V to 5.5 V, with VCC(B) ≥ VCC(A) enforced. At 1.8 V/5.0 V, it delivers 1.0 ns minimum propagation delay and maintains VIH/VIL compatibility with both 1.8 V CMOS and 5 V TTL inputs, validated per Table 5 and Table 6 of the datasheet.
What happens to the outputs during power sequencing when VCC(A) ramps before VCC(B)?
When VCC(A) is powered but VCC(B) = 0 V, the IOFF circuit forces all B-side outputs into high-impedance state with leakage < ±0.1 μA. A-side outputs remain functional if 1OE/2OE are asserted, preventing back-current flow from the 5 V domain into the unpowered B-side supply rail.
Is the 74ALVC164245DGG:11 pin-compatible with older 74LVC164245 variants?
No. While both use TSSOP48 (SOT362-1), the 74ALVC164245DGG:11 has different pin assignments for VCC(A)/VCC(B) and GND locations per Figure 1 pinning diagram. Specifically, VCC(A) appears on pins 31 and 42, whereas 74LVC164245 uses pins 2 and 47 - requiring PCB layout revision for replacement.
Does this transceiver support hot-swap insertion in live backplanes?
Yes. The combination of IOFF protection, overvoltage-tolerant inputs (5.5 V), and guaranteed high-impedance behavior during VCC mismatch enables safe hot-insertion. When inserted into a live 5 V backplane, the unpowered A-side remains isolated until VCC(A) stabilizes, preventing glitch generation or supply rail disturbance.
