Product details
Overview
74ALVC164245PVG from Renesas Electronics (formerly IDT) is a 16-bit bidirectional 3.3V-to-5V level-shifting transceiver with 3-state outputs, dual-supply operation (VCCA = 2.7–3.6V, VCCB = 4.5–5.5V), ±24mA drive strength, and industrial temperature range (–40°C to +85°C). It enables asynchronous data bus communication between mixed-voltage systems such as 3.3V logic and 5V PCI interfaces.
For engineers reviewing the 74ALVC164245PVG datasheet, 74ALVC164245PVG pinout, 74ALVC164245PVG application, or 74ALVC164245PVG equivalent, key selection criteria include verified bidirectional level translation capability, output skew < 250ps, rail-to-rail swing for noise margin, ESD robustness (>2000V HBM), and SSOP-48 package compatibility with legacy 5V/3.3V system interconnects.
Technical Context
The 74ALVC164245PVG implements two independent 8-bit bidirectional data paths, each controlled by dedicated DIR and OE signals referenced to VCCA. Its dual-rail architecture isolates A-port (3.3V domain) and B-port (5V domain) logic levels while maintaining signal integrity across voltage domains.
It uses advanced 0.5µm CMOS technology with high-drive output buffers capable of sourcing/sinking ±24mA per pin on both ports, supporting heavy capacitive loads without compromising propagation delay (tPLH/tPHL ≤ 5.9ns at VCCA = 3.3V, VCCB = 5V). Output disable timing (tPZL/tPHZ ≤ 10.2ns) ensures clean bus contention avoidance in shared-data applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCCA Range | 2.7V to 3.6V - powers A-port I/O and control inputs (DIR, OE), enabling direct interface with 3.3V logic families. |
| VCCB Range | 4.5V to 5.5V - powers B-port I/O, ensuring compatibility with standard 5V TTL/CMOS buses including PCI. |
| Drive Strength | ±24mA per output - supports driving 50Ω transmission lines or multiple LVTTL loads without external buffering. |
| Propagation Delay | ≤5.9ns (A→B), ≤6.7ns (B→A) - enables high-speed bidirectional data transfer up to ~100MHz system clock rates. |
| Output Skew | <250ps - minimizes timing mismatch across 16-bit data words, critical for parallel bus integrity. |
| ESD Rating | >2000V HBM, >200V MM - provides robust handling during board assembly and field operation in industrial environments. |
| Operating Temp | –40°C to +85°C - qualified for use in industrial control, telecom infrastructure, and embedded computing systems. |
Pinout & Package
74ALVC164245PVG is housed in a 48-pin Shrink Small Outline Package (SSOP), package code PVG48, with 0.5mm lead pitch and exposed pad not present. Pin spacing and thermal profile comply with JEDEC MO-153 standards for surface-mount reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction Control Input (Active HIGH) | Configures data flow direction per 8-bit bank: HIGH = A→B, LOW = B→A; referenced to VCCA. |
| 1OE, 2OE | Output Enable Input (Active LOW) | Places corresponding 8-bit port outputs into high-impedance state when HIGH; referenced to VCCA. |
| 1A1–1A8, 2A1–2A8 | A-Port I/O Pins | 3.3V-domain bidirectional data terminals; tolerate input voltages up to 6V per absolute max rating. |
| 1B1–1B8, 2B1–2B8 | B-Port I/O Pins | 5V-domain bidirectional data terminals; support 5V-tolerant inputs and rail-to-rail output swing. |
| VCCA, GND (A-side) | A-Port Power/Ground | Dedicated supply and return for A-port logic and control circuitry; decoupling required near pins 23/24 and 39/40. |
| VCCB, GND (B-side) | B-Port Power/Ground | Dedicated supply and return for B-port drivers; separate decoupling recommended near pins 4/5 and 20/21. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Level Translation | Simultaneous 3.3V↔5V translation per 8-bit channel with independent DIR/OE control-enables flexible bus arbitration in mixed-voltage backplanes. |
| Rail-to-Rail Output Swing | VOH ≥ VCC–0.2V and VOL ≤ 0.55V across full load range-maximizes noise margin in electrically noisy industrial environments. |
| Low Static Power | ICCL ≤ 40µA typical-reduces quiescent current in always-on subsystems like power management supervisors or configuration bridges. |
| High-Speed Timing | tPZH/tPHZ ≤ 10.2ns-supports fast enable/disable cycles for time-multiplexed bus sharing without glitches. |
| Robust I/O Protection | VTERM(3) = –0.5V to +6V-allows safe interfacing with hot-pluggable modules or legacy 5V peripherals without level-shifter front-end protection. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar level-shifting transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AVCH16T245DGGR | Single-supply (1.2–3.6V), auto-sensing direction, lower drive (±12mA), smaller TSSOP-48 package. | Better suited for ultra-low-voltage portable systems; lacks native 5V I/O tolerance-requires external clamping for 5V bus interfacing. | Select when migrating to single-supply designs or when space-constrained layouts favor TSSOP over SSOP. |
| TXS0108EPWR | Auto-bidirectional, open-drain compatible, lower speed (tPD ≤ 22ns), 1.65–5.5V dual-rail, 20-pin TSSOP. | Designed for I²C/SMBus translation; unsuitable for high-speed parallel bus applications due to slower timing and no 3-state control. | Choose only for low-speed, low-pin-count, open-drain protocol translation-not for 16-bit parallel data paths. |
Compared with SN74AVCH16T245DGGR and TXS0108EPWR, the 74ALVC164245PVG uniquely delivers native 5V-tolerant B-port I/O, ±24mA drive, and sub-6ns propagation delay in an industrial-grade SSOP package-making it irreplaceable for high-speed, mixed-voltage parallel bus bridging where timing and drive strength are non-negotiable.

FAQ
What voltage rails does the 74ALVC164245PVG support, and how are they assigned?
The 74ALVC164245PVG supports two independent voltage rails: VCCA (2.7V to 3.6V) powers the A-port I/O and all control inputs (DIR, OE), while VCCB (4.5V to 5.5V) powers the B-port I/O drivers. This separation enables true bidirectional 3.3V-to-5V level shifting without level-shifter biasing components. Both supplies must be present and stable for correct 74ALVC164245PVG operation.
Can the 74ALVC164245PVG operate with VCCA = 2.7V and VCCB = 4.5V simultaneously?
Yes, the 74ALVC164245PVG is fully specified to operate across its entire rated voltage ranges: VCCA = 2.7V to 3.6V and VCCB = 4.5V to 5.5V. At VCCA = 2.7V and VCCB = 4.5V, DC parameters including VIH/VIL thresholds and output drive remain compliant per the datasheet's industrial-range specifications. The 74ALVC164245PVG maintains timing performance (e.g., tPLH ≤ 5.9ns) even at these minimum supply extremes.
Does the 74ALVC164245PVG support hot-swap or live-insertion into a powered 5V bus?
The 74ALVC164245PVG features VTERM(3) = –0.5V to +6V on all I/O pins (except VCC), allowing safe connection to a live 5V bus prior to VCCA/VCCB ramp-up. However, proper power sequencing-applying VCCA before enabling OE-is recommended to avoid undefined states. The 74ALVC164245PVG's 2000V HBM ESD rating further enhances robustness during field maintenance operations.
How many independent data paths does the 74ALVC164245PVG provide, and how are they controlled?
The 74ALVC164245PVG provides two independent 8-bit bidirectional data paths (Bank 1: A1–A8 ↔ B1–B8; Bank 2: A9–A16 ↔ B9–B16), each with dedicated DIR and OE pins (1DIR/1OE and 2DIR/2OE). Control signals are referenced to VCCA, enabling synchronous or asynchronous operation of each bank. This architecture allows simultaneous or staggered data transfers-critical for 74ALVC164245PVG use in segmented bus architectures.
Is the 74ALVC164245PVG pin-compatible with other ALVC164245 variants like the PAG version?
Yes, the 74ALVC164245PVG (SSOP-48) shares identical pinout and electrical functionality with the TSSOP-48 variant 74ALVC164245PAG. Both use the same 48-pin footprint, matching pin assignments for all signals, power, and ground terminals. Mechanical differences (body size, lead pitch, thermal pad presence) do not affect schematic design or logic-level behavior-making the 74ALVC164245PVG a drop-in replacement where SSOP packaging is preferred for legacy board compatibility.
