Product details
Overview
74ALVC162245PAG8 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 dual 8-bit sections, ±12mA drive on A port, ±24mA drive on B port, and operates across –40°C to +85°C.
For engineers reviewing the 74ALVC162245PAG8 datasheet, 74ALVC162245PAG8 pinout, 74ALVC162245PAG8 application, or 74ALVC162245PAG8 equivalent, key selection factors include direction-controlled bidirectional flow, rail-to-rail output swing, low output skew (<500ps), and TSSOP-48 packaging for high-density PCB layouts.
Technical Context
The 74ALVC162245PAG8 implements two independent 8-bit transceiver sections, each with separate DIR and OE controls, enabling flexible 8-bit or unified 16-bit operation. Its dual-drive architecture provides asymmetric output strength: A-port drivers are series-resistor-limited to ±12mA, while B-port drivers deliver ±24mA without internal limiting.
It supports three VCC operating ranges: 2.5V ±0.2V, 2.7V–3.6V, and nominal 3.3V ±0.3V. Input thresholds are hysteresis-enhanced (100mV typical), and output enable/disable timing is optimized for low propagation delay (tPLH/tPHL ≤ 4.2ns at 3.3V) and tight skew control (tSK(o) ≤ 500ps).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.5V ±0.2V, 2.7V–3.6V, or 3.3V ±0.3V - ensures compatibility with mixed-voltage 3.3V/2.5V system domains |
| Drive Strength | A port: ±12mA; B port: ±24mA - enables direct interface to varied load types without external buffers |
| Propagation Delay | tPLH/tPHL ≤ 4.2ns (B port, VCC = 3.3V) - supports >200MHz bus toggle rates in synchronous designs |
| Output Skew | tSK(o) ≤ 500ps - maintains signal integrity across all 16 outputs during parallel data transfers |
| Input Hysteresis | 100mV typical - improves noise immunity on control lines in electrically noisy industrial environments |
| ESD Rating | >2000V HBM, >200V MM - meets MIL-STD-883 requirements for robust handling and board-level reliability |
| Operating Temp | –40°C to +85°C - certified for industrial temperature range operation without derating |
Pinout & Package
TSSOP-48 package (4.4mm × 9.7mm body, 0.5mm pitch), lead-free and RoHS-compliant, optimized for automated assembly and thermal performance in space-constrained industrial PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction Control Inputs (Active HIGH) | Determines data flow direction per 8-bit section: HIGH = A→B, LOW = B→A |
| 1OE, 2OE | Output Enable Inputs (Active LOW) | Disables both A and B ports to high-impedance state when HIGH, isolating buses |
| 1A1–1A8, 2A1–2A8 | Side-A I/O Terminals | 8-bit bidirectional port with ±12mA drive and integrated series resistance for EMI reduction |
| 1B1–1B8, 2B1–2B8 | Side-B I/O Terminals | 8-bit bidirectional port with ±24mA drive for higher fan-out or longer trace loads |
| VCC, GND (×4) | Power and Ground | Multiple distributed VCC/GND pairs minimize switching noise and improve PSRR |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | VOH ≥ VCC – 0.2V, VOL ≤ 0.2V - maximizes noise margin in 3.3V logic systems |
| Asymmetric drive capability | Separate ±12mA (A) and ±24mA (B) outputs - allows optimal driver matching to source/sink load asymmetry |
| Low static power | ICCL ≤ 40µA typical - reduces quiescent current in always-on industrial control modules |
| Input hysteresis | 100mV typical - suppresses chatter on slow-rising control signals in noisy factory environments |
| Output skew control | tSK(o) ≤ 500ps - guarantees deterministic timing alignment across all 16 outputs for parallel bus integrity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ALVC162245DGGR | TI variant in TSSOP-48; identical electrical specs but different VIL/VIH thresholds at 2.5V VCC | Same industrial temp range and pinout; minor DC threshold variance affects margin in 2.5V-only systems | Select when sourcing from TI distribution channels or requiring TI-specific qualification documentation |
| 74LVC162245APAG | Renesas LVC variant; lower drive (±24mA only on both ports), no A-port series resistors, 1.65V–3.6V VCC range | Better for ultra-low-voltage operation but lacks A-port EMI suppression; not drop-in due to differing drive behavior | Choose for cost-sensitive 1.8V/3.3V mixed-signal systems where A-port noise control is noncritical |
Compared with SN74ALVC162245DGGR and 74LVC162245APAG, the 74ALVC162245PAG8 uniquely combines asymmetric drive (±12mA/±24mA), integrated A-port series termination, and guaranteed industrial temperature performance - making it optimal for noise-sensitive, high-reliability backplane and instrumentation interfaces.

FAQ
What is the maximum operating frequency supported by the 74ALVC162245PAG8?
The 74ALVC162245PAG8 does not specify a maximum clock frequency, as it is an asynchronous transceiver. Its usable data rate depends on propagation delay and system timing margins: with tPLH/tPHL ≤ 4.2ns (B port, 3.3V), it reliably supports bus toggle rates exceeding 200MHz in well-terminated, low-skew layouts. Actual throughput is determined by external control signal timing and PCB interconnect design.
Does the 74ALVC162245PAG8 support level translation between 2.5V and 3.3V buses?
Yes, the 74ALVC162245PAG8 supports mixed-voltage operation: its VCC range includes 2.5V ±0.2V and 3.3V ±0.3V, and input thresholds scale with VCC. When powered at 3.3V, it accepts 2.5V logic inputs (VIH min = 2.0V); when powered at 2.5V, outputs swing rail-to-rail (VOH ≥ 2.3V), compatible with 2.5V receivers. No external level shifters are needed for 2.5V↔3.3V interfacing.
How does the A-port series resistance in the 74ALVC162245PAG8 improve system performance?
The 74ALVC162245PAG8 integrates series resistors on all A-port outputs to dampen signal edge ringing and reduce EMI radiation - especially beneficial when driving light loads (e.g., short PCB traces or high-impedance inputs). This built-in termination eliminates the need for discrete 10–33Ω resistors per line, saving board space and improving signal integrity without compromising ±12mA drive capability or timing specifications.
Can the 74ALVC162245PAG8 be used in a single 8-bit configuration?
Yes, the 74ALVC162245PAG8 contains two fully independent 8-bit transceiver sections (1A/1B and 2A/2B), each with dedicated DIR and OE controls. Either section can be used standalone while the other is disabled (OE HIGH), enabling flexible partitioning for 8-bit data paths, isolated control buses, or redundant signal routing - all within one TSSOP-48 package.
What is the meaning of "PAG8" in the part number 74ALVC162245PAG8?
"PAG8" denotes the package and environmental specification: "PAG" indicates a 48-pin Thin Shrink Small Outline Package (TSSOP) with green (lead-free/RoHS-compliant) finish; "8" signifies tape-and-reel packaging per JEDEC standard J-STD-020, with 1000 units per reel - standard for automated SMT assembly. This matches the official Renesas ordering code structure shown in the datasheet's Ordering Information table.
