Product details
Overview
74ALVC16245PAG8 from Renesas Electronics (formerly IDT) is a 3.3V CMOS 16-bit bus transceiver with 3-state outputs, designed for asynchronous bidirectional data transfer between A and B buses in industrial-grade systems. It features ±24mA drive strength, 3.3V ±0.3V supply operation, <500ps output skew, and TSSOP-48 package. Used in 3.3V high-speed computing interconnects where bus isolation and heavy-load driving are required.
For engineers reviewing the 74ALVC16245PAG8 datasheet, 74ALVC16245PAG8 pinout, 74ALVC16245PAG8 application, or 74ALVC16245PAG8 equivalent, key selection criteria include direction-control logic behavior, 3-state enable timing (tPZH/tPHZ), industrial temperature range (–40°C to +85°C), and compatibility with mixed-voltage 2.5V/3.3V system interfaces.
Technical Context
The 74ALVC16245PAG8 implements dual 8-bit transceiver sections with independent DIR and OE controls per section, enabling flexible data flow routing-A→B or B→A-based on DIR logic level. Each section supports true 3-state output disable via active-low OE, isolating both buses when asserted.
It uses advanced 0.5µm CMOS technology with rail-to-rail output swing, delivering robust noise margin and low static power (0.4µW typ). Output skew is specified at ≤500ps across same-direction switching outputs, critical for timing-critical parallel bus synchronization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.7V to 3.6V - supports extended 3.3V system tolerance and backward compatibility with 2.5V logic |
| Output Drive | ±24mA - enables direct driving of moderate-to-heavy capacitive loads without external buffers |
| tPLH / tPHL | 1ns to 3ns @ VCC = 3.3V - ensures sub-3.5ns propagation delay for high-throughput data paths |
| tPZH / tPHZ | 1ns to 4.4ns @ VCC = 3.3V - guarantees fast bus enable/disable transitions for dynamic bus sharing |
| tSK(o) | ≤500ps - minimizes timing skew across 16-bit data words, preserving setup/hold integrity |
| Operating Temp | –40°C to +85°C - qualified for industrial environments without derating |
| Input Capacitance | 5–7pF - reduces loading on upstream drivers and improves signal integrity at high frequencies |
Pinout & Package
74ALVC16245PAG8 is housed in a 48-pin Thin Shrink Small Outline Package (TSSOP), lead-free and RoHS-compliant, with 0.5mm pitch and exposed thermal pad (per Renesas green packaging standard).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction Control Input (Active HIGH) | Determines data flow direction per 8-bit section: HIGH = A→B, LOW = B→A |
| 1OE, 2OE | Output Enable Input (Active LOW) | Disables all outputs in associated section to high-impedance state when HIGH |
| 1A1–1A8, 2A1–2A8 | Side-A I/O Port | Bi-directional pins for first/second 8-bit bus segment; function as inputs or 3-state outputs |
| 1B1–1B8, 2B1–2B8 | Side-B I/O Port | Bi-directional pins for complementary 8-bit bus segment; mirror behavior of Side-A under DIR control |
| VCC (Pins 4, 20, 36, 48) | Power Supply | Four dedicated VCC pins reduce IR drop and improve noise immunity across wide TSSOP body |
| GND (Pins 3, 19, 35, 47) | Ground Reference | Four GND pins provide low-inductance return paths and stabilize switching noise |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Maximizes noise margin in 3.3V systems by driving full VCC–GND voltage range |
| ±24mA output drive | Eliminates need for external line drivers when interfacing with 50Ω traces or >30pF loads |
| Low output skew (≤500ps) | Preserves parallel data validity across all 16 bits during high-speed burst transfers |
| CMOS static power (0.4µW typ) | Enables use in always-on subsystems without thermal or battery-life penalty |
| ESD protection (>2kV HBM) | Reduces risk of field failure during board handling and system integration |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ALVC16245PAG | Same pinout, identical electrical specs, TI-manufactured variant; slightly higher ICCZ (750µA vs 40µA max) | Valid for TI-based BOMs; requires validation of TI's thermal derating curve above 70°C | Select if sourcing from TI distribution channels or aligning with TI reference designs |
| 74LVC16245APAG | Lower drive (±24mA same), but narrower VCC range (1.65V–3.6V); lacks 2.5V-specific characterization | Suitable for ultra-low-voltage portable systems; not recommended for industrial 2.5V-only rails due to missing 2.5V timing data | Prefer only when operating below 2.7V or integrating with 1.8V logic families |
Compared with SN74ALVC16245PAG and 74LVC16245APAG, the 74ALVC16245PAG8 offers tighter ICCZ control (≤40µA), full 2.5V/3.3V timing validation, and Renesas' industrial reliability qualification-making it optimal for mission-critical embedded infrastructure where supply stability and long-term availability matter.

FAQ
What is the maximum operating frequency supported by the 74ALVC16245PAG8?
The 74ALVC16245PAG8 does not specify a maximum clock frequency, as it is an asynchronous transceiver. Its usable data rate depends on system-level timing constraints-including propagation delay (tPLH/tPHL ≤3ns), output skew (≤500ps), and PCB trace length. In practice, it reliably supports sustained 50MHz parallel bus operation with proper layout and termination. The 74ALVC16245PAG8 is commonly deployed in 33–66MHz industrial backplanes where timing margins are verified using worst-case skew and delay values from the datasheet.
Does the 74ALVC16245PAG8 support mixed-voltage operation between 2.5V and 3.3V buses?
Yes-the 74ALVC16245PAG8 operates across VCC = 2.7V to 3.6V and is characterized at both 2.5V ±0.2V and 3.3V ±0.3V. Its input thresholds (VIH/VIL) scale with VCC, allowing safe interfacing between 2.5V drivers and 3.3V receivers-or vice versa-when powered at 3.3V. The 74ALVC16245PAG8 must be powered from the higher-voltage rail (e.g., 3.3V) when bridging domains; its outputs swing rail-to-rail, ensuring compatible logic levels on both sides.
How many independent transceiver sections does the 74ALVC16245PAG8 contain?
The 74ALVC16245PAG8 contains two independent 8-bit transceiver sections (Section 1: pins 1A1–1A8/1B1–1B8; Section 2: pins 2A1–2A8/2B1–2B8), each with dedicated DIR and OE controls. This allows simultaneous or staggered bidirectional data transfer-for example, A→B on Section 1 while B→A on Section 2-without internal contention. The 74ALVC16245PAG8 thus provides flexibility beyond a single 16-bit pipe, supporting segmented bus architectures.
What is the meaning of "PAG8" in the part number 74ALVC16245PAG8?
"PAG8" denotes the package and environmental specification: "PA" = Thin Shrink Small Outline Package (TSSOP), "G" = Green (lead-free, RoHS-compliant), and "8" = tape-and-reel packaging format per JEDEC standard J-STD-020. The 74ALVC16245PAG8 is supplied in 1000-unit reels, optimized for automated SMT assembly. This suffix distinguishes it from tray-packaged (PAG) or non-RoHS variants.
Can the 74ALVC16245PAG8 be used in place of the older 74ALVC16244?
No-the 74ALVC16245PAG8 is a transceiver (bidirectional), whereas the 74ALVC16244 is a unidirectional buffer. They differ in pinout, functionality (DIR input presence), and truth table behavior. Replacing 74ALVC16244 with 74ALVC16245PAG8 would require redesigning control logic and verifying signal flow directionality. The 74ALVC16245PAG8 is not a drop-in substitute; it serves distinct system roles requiring bidirectional bus arbitration.
