Product details
Overview
74LVTN16245BBX,518 from Nexperia is a 3.3 V, 16-bit non-inverting bus transceiver with dual 3-state outputs, BiCMOS architecture, ±32 mA/±64 mA drive capability, and TTL-compatible I/O for mixed-voltage interfacing (3.3 V core ↔ 5 V bus). It enables bidirectional data flow between two 16-bit buses in industrial control backplanes and memory expansion subsystems.
For engineers reviewing the 74LVTN16245BBX,518 datasheet, 74LVTN16245BBX,518 pinout, 74LVTN16245BBX,518 application, or 74LVTN16245BBX,518 equivalent, key selection criteria include direction-controlled 3-state timing, 5 V-tolerant inputs, power-up 3-state safety, live insertion support, and TSSOP48 thermal performance at -40 °C to +85 °C.
Technical Context
This device implements two independent 8-bit transceiver sections (A↔B), each controlled by dedicated nDIR (direction) and nOE (output enable) inputs. Its BiCMOS process delivers fast propagation delays (1.0–3.3 ns typical) while maintaining TTL-level input thresholds and 5 V-tolerant I/O pins.
The functional table confirms deterministic behavior: when nOE = LOW, data flows bidirectionally per nDIR state (A→B or B→A); when nOE = HIGH, both sides enter high-impedance OFF-state regardless of nDIR. Power-up 3-state ensures bus isolation during power ramp-up.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 2.7 V to 3.6 V - Ensures stable operation across 3.3 V ±10 % rail tolerances in modern logic systems. |
| IOH / IOL | -32 mA / +64 mA - Supports driving heavy capacitive loads and legacy 5 V TTL buses without level shifters. |
| tPLH / tPHL | 1.0–3.3 ns - Enables >200 MHz bus clocking in high-speed parallel interfaces with tight timing margins. |
| VIH / VIL | ≥2.0 V / ≤0.8 V - Guarantees reliable recognition of 5 V TTL logic levels on inputs despite 3.3 V supply. |
| Operating Temp | -40 °C to +85 °C - Validated for industrial-grade embedded systems including PLCs and motor drives. |
| ESD Rating | HBM >2000 V, CDM >1000 V - Meets IEC 61000-4-2 system-level robustness requirements for field-deployed equipment. |
Pinout & Package
TSSOP48 package (SOT362-1), 6.1 mm body width, 0.5 mm lead pitch, 12.6 mm × 6.2 mm footprint, 1.2 mm max height - optimized for high-density PCB layouts with thermal vias under exposed pad (GND).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input | Active-HIGH logic selects A→B (DIR=HIGH) or B→A (DIR=LOW) per section; asynchronous to OE. |
| 1OE, 2OE | Output enable input | Active-LOW enables/disables entire 8-bit section; powers down output stage to reduce bus leakage. |
| 1A0–1A7, 2A0–2A7 | Data port A terminals | Side-A I/O pins; tolerate 0–5.5 V input voltage and drive 3.3 V logic or 5 V TTL loads. |
| 1B0–1B7, 2B0–2B7 | Data port B terminals | Side-B I/O pins; electrically identical to A-side; supports hot-swap via live insertion rating. |
| VCC (pins 7,18,31,42) | Supply voltage | Four distributed VCC pins minimize IR drop and improve noise immunity across wide bus widths. |
| GND (pins 4,10,15,21,28,34,39,45) | Ground reference | Eight GND pins provide low-inductance return paths for high-speed switching currents. |
Key Features
| Feature | Design Value |
|---|---|
| 5 V-tolerant I/O | Inputs accept 0–5.5 V; outputs drive 5 V TTL loads directly - eliminates external level translators in mixed-voltage systems. |
| Power-up 3-state | Outputs remain in high-impedance until VCC ≥ 1.2 V - prevents bus contention during power sequencing in multi-rail systems. |
| Live insertion support | Rated for hot-plug operation without latch-up or damage - enables modular backplane designs with field-replaceable cards. |
| Latch-up immunity | JESD78B Class II (>500 mA) - withstands transient overcurrent events common in industrial ESD environments. |
Applications
| Industrial Backplane Interface | Memory Expansion Subsystem |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC16245ADGGR | Lower drive (±24 mA), 1.65–3.6 V VCC range, no 5 V-tolerant inputs | Requires external level shifting for 5 V bus interfacing; unsuitable for live insertion | Select only for pure 3.3 V systems where cost is prioritized over mixed-voltage flexibility. |
| 74ALVC16245PW,118 | Same 5 V-tolerance and drive, but LVTTL-compatible (not TTL) input thresholds; higher ICC (0.2 mA typical) | Marginally less noise-immune on 5 V inputs; increased quiescent power in always-on monitoring nodes | Prefer when strict LVTTL signaling is required; avoid in noisy industrial environments with marginal VIH. |
Compared with SN74LVC16245ADGGR and 74ALVC16245PW,118, the 74LVTN16245BBX,518 uniquely combines 5 V-tolerant TTL inputs, ±64 mA sink strength, and live-insertion qualification - making it the only choice for ruggedized 3.3 V/5 V bridging in field-deployable equipment.

FAQ
What is the maximum bus capacitance this transceiver can reliably drive?
The 74LVTN16245BBX,518 supports up to 50 pF load capacitance per pin as verified in the test circuit (Fig. 5) with 500 Ω termination and 50 pF CL. At 64 mA sink current and 3.3 V VCC, it maintains VOL ≤ 0.55 V under these conditions, ensuring signal integrity on moderately loaded backplanes.
Does this device require external pull-up or pull-down resistors on control pins?
No external biasing is required: nOE and nDIR inputs have CMOS-compatible thresholds and negligible leakage (<±1 μA at VCC = 3.6 V). Internal design ensures defined logic states with open-circuit or microcontroller-driven control lines - simplifying PCB layout and reducing BOM count.
Can this transceiver be used in automotive applications?
No - the 74LVTN16245BBX,518 is not AEC-Q100 qualified and lacks automotive-grade screening, temperature validation beyond +85 °C, or enhanced ESD robustness required for vehicle ECUs. Nexperia explicitly states non-automotive qualification in its legal disclaimers.
How does the power-up 3-state feature behave during brown-out conditions?
During VCC ramp-up below 1.2 V, outputs remain in high-impedance regardless of nOE/nDIR states. Between 1.2 V and 3.3 V ±0.3 V, transition time must be ≤100 μs to guarantee safe 3-state behavior; slower ramps risk temporary contention - use proper power sequencing or supervisor ICs in critical systems.
