Product details
Overview
74ALVC16245DGG,512 from Nexperia is a 16-bit dual-directional bus transceiver with independent 3-state control per 8-bit bank, operating from 1.2 V to 3.6 V supply, featuring IOFF partial power-down protection and Schmitt-trigger inputs for noise immunity. It supports bidirectional data flow between two 8-bit buses or one 16-bit bus in industrial control backplanes and memory-mapped peripheral interfaces.
For engineers reviewing the 74ALVC16245DGG,512 datasheet, 74ALVC16245DGG,512 pinout, 74ALVC16245DGG,512 application, or 74ALVC16245DGG,512 equivalent, key selection criteria include voltage range compatibility (1.2–3.6 V), IOFF-enabled system-level power sequencing, dual OE/DIR control granularity, and TSSOP48 thermal and routing constraints.
Technical Context
This device implements two independent 8-bit transceiver banks, each with dedicated direction (1DIR/2DIR) and output enable (1OE/2OE) inputs. Its CMOS architecture delivers ±24 mA drive strength at 3.0 V while maintaining low ICC (≤40 μA) under static conditions and supporting 50 Ω transmission line termination at 85 °C.
The IOFF circuit disables outputs during power-down to prevent backflow current, and Schmitt-trigger inputs tolerate slow signal edges-critical for mixed-voltage board interconnects. Unlike the ALVCH variant, this ALVC version lacks bus-hold but supports 5.5 V overvoltage-tolerant inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.2 V to 3.6 V - enables direct interface with 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters |
| Propagation Delay | 1.0–3.0 ns at VCC = 3.0–3.6 V - supports >300 MHz bus toggle rates in high-speed parallel interfaces |
| Output Drive | ±24 mA at 3.0 V - sufficient to drive 50 Ω PCB traces or fan-out to ≥10 LVTTL loads |
| IOFF Protection | Active during VCC = 0 V - blocks destructive current flow when one side of bus is powered down |
| Input Voltage Range | −0.5 V to +4.6 V - allows safe interfacing with 5 V legacy peripherals without external clamping |
| Operating Temperature | −40 °C to +85 °C - qualified for industrial-grade embedded systems and base station control modules |
| ESD Rating | HBM >2000 V, CDM >1000 V - reduces risk of handling damage during manual assembly or field rework |
Pinout & Package
TSSOP48 (SOT362-1) package: plastic thin shrink small outline, 48 leads, 6.1 mm body width, 0.5 mm lead pitch, designed for fine-pitch PCB routing and thermal dissipation in dense logic arrays.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR (Pins 1, 24) | Direction control input | Active-HIGH signal selects data flow direction per 8-bit bank (A→B or B→A) |
| 1OE, 2OE (Pins 48, 25) | Output enable input | Active-LOW control independently places each 8-bit output bank into high-impedance state |
| 1A0–1A7 (Pins 47, 46, 44, 43, 41, 40, 38, 37) | Data port A I/O | First 8-bit bidirectional bus interface; connects to microcontroller or FPGA data bus |
| 1B0–1B7 (Pins 2, 3, 5, 6, 8, 9, 11, 12) | Data port B I/O | Second 8-bit bidirectional bus interface; typically links to memory or peripheral ASIC |
| 2A0–2A7 (Pins 36, 35, 33, 32, 30, 29, 27, 26) | Data port A I/O (Bank 2) | Upper 8-bit segment of second transceiver bank; shares same functional role as 1A0–1A7 |
| 2B0–2B7 (Pins 13, 14, 16, 17, 19, 20, 22, 23) | Data port B I/O (Bank 2) | Upper 8-bit segment of second transceiver bank; routed separately for parallel bus expansion |
| VCC (Pins 7, 18, 31, 42) | Power supply | Four distributed VCC pins minimize IR drop and supply noise across high-speed switching banks |
| GND (Pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight GND pins ensure low-inductance return paths, critical for signal integrity at >100 MHz edge rates |
Key Features
| Feature | Design Value |
|---|---|
| MULTIBYTE™ flow-through pinout | Minimizes trace crossovers on 2-layer PCBs by aligning A/B port pins in sequential physical order |
| IOFF partial power-down | Prevents back-current when VCC = 0 V, enabling hot-swap capability in modular backplane systems |
| Schmitt-trigger inputs | Provides 0.3–0.5 V hysteresis to reject noise on slow-rising control lines (e.g., reset or enable signals) |
| Overvoltage-tolerant inputs | Accepts up to +4.6 V on data/control pins while powered from 1.2–3.6 V - eliminates external clamps for 5 V-tolerant design |
| Low ground bounce | Dual VCC/GND pin pairs per bank reduce simultaneous switching noise during full-bus toggling |
Applications
| Industrial PLC Backplane Interface | Memory-Mapped Peripheral Bridge |
|---|---|
Use Scenario: Bidirectional data exchange between ARM-based controller and isolated I/O modules via 16-bit parallel bus. IC Role / Device Role / Timing Role: Level-shifting transceiver managing direction and tristate control for time-critical register reads/writes. Use Value: IOFF prevents latch-up during module hot-insertion; Schmitt inputs suppress EMI-induced glitches on long backplane traces. |
Use Scenario: Connecting an FPGA's 16-bit data bus to legacy SRAM or EPROM with asymmetric timing requirements. IC Role / Device Role / Timing Role: Synchronizing read/write strobes and data flow direction across voltage-domain boundaries. Use Value: 1.2–3.6 V operation matches FPGA core voltage; 3.0 ns max propagation delay meets 100 MHz SRAM access timing. |
| FPGA-to-ASIC Communication Link | Multi-Processor Shared Bus Arbitration |
Use Scenario: High-speed data transfer between Xilinx Artix FPGA and custom ASIC using shared 16-bit address/data multiplexed bus. IC Role / Device Role / Timing Role: Isolating bus segments during arbitration and enabling clean direction reversal on command.

IC Role / Device Role / Timing Role: Acting as a controllable bus barrier that isolates inactive masters during active cycles. Use Value: 8 GND pins and low-output impedance (≤10 Ω) maintain signal fidelity across multiple drivers and stubs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74ALVCH16245DGG | Includes bus-hold on all data inputs; no 5.5 V overvoltage tolerance | Eliminates need for external pull-ups on floating data lines; less suitable for 5 V legacy interfacing | Select when unused bus lines must be held without external resistors, and 5 V tolerance is unnecessary |
| SN74LVC16245ADGGR | Texas Instruments part; identical pinout and function; rated for −40 °C to +125 °C | Extended temperature range supports automotive under-hood use cases not covered by Nexperia's −40 °C to +85 °C spec | Select for extended-temp environments where TI qualification and sourcing stability are prioritized |
Compared with 74ALVC16245DGG,512, the ALVCH variant adds bus-hold at the cost of 5 V tolerance, while the TI SN74LVC16245ADGGR offers wider temperature coverage but requires validation of timing equivalence in high-speed layouts.

FAQ
Can 74ALVC16245DGG,512 operate at 1.8 V with guaranteed timing?
Yes. The device is fully specified from 1.2 V to 3.6 V, and its propagation delay is characterized at 1.8 V (within the 1.2–2.7 V range). At VCC = 1.8 V, typical tpd is 2.0 ns with CL = 30 pF, meeting timing for 100 MHz synchronous bus protocols.
Does 74ALVC16245DGG,512 support hot-swap insertion?
Yes, due to its IOFF circuitry. When VCC = 0 V, the outputs enter a high-impedance state and block current flow from live bus lines, preventing damage during live insertion into powered backplanes or carrier boards.
What is the maximum capacitive load this transceiver can drive reliably?
The device is characterized for CL = 30 pF (at 2.3–2.7 V) and CL = 50 pF (at 3.0–3.6 V). With 50 Ω transmission line drive capability at 85 °C, it reliably drives ≤50 pF loads including PCB trace capacitance, connector parasitics, and input capacitance of downstream devices.
How does the Schmitt-trigger input improve noise immunity?
Schmitt-trigger inputs provide 0.3–0.5 V hysteresis, meaning the rising and falling thresholds differ significantly. This prevents multiple output transitions caused by slow-rising or noisy control signals (e.g., long traces near motors or switching regulators), ensuring deterministic direction and enable behavior.
