Product details
Overview
SN74LVC16245ADGVR from Texas Instruments is a 16-bit dual-octal noninverting bus transceiver with 3-state outputs, designed for asynchronous bidirectional data transfer between 1.65–3.6-V buses. It supports mixed-mode signal operation (5.5-V-tolerant inputs at 3.3-V VCC), delivers ≤4 ns propagation delay at 3.3 V, and enables isolated bus communication in industrial I/O subsystems.
For engineers reviewing the SN74LVC16245ADGVR datasheet, SN74LVC16245ADGVR pinout, SN74LVC16245ADGVR application, or SN74LVC16245ADGVR equivalent, key selection criteria include its 48-pin TVSOP package, Ioff-enabled live insertion capability, ±24-mA output drive at 3.0-V VCC, and guaranteed operation from –40°C to +125°C.
Technical Context
The SN74LVC16245ADGVR implements two independent 8-bit transceiver channels-each with dedicated direction (DIR) and output-enable (OE) controls-allowing simultaneous A→B or B→A data flow per channel. Its CMOS design ensures balanced drive strength and low ground bounce (VOLP < 0.8 V at VCC = 3.3 V).
It features 5.5-V-tolerant inputs across all valid VCC (1.65–3.6 V), enabling seamless level translation in mixed-voltage systems. The Ioff circuitry actively disables outputs when VCC = 0 V, preventing back-drive current and supporting partial-power-down operation.
Key Specifications

| 1B1–1B8, 2B1–2B8 | Port B I/O terminals | First and second 8-bit data bus interface on B side; identical electrical specs to Port A |
| VCC (Pins 7, 18, 31, 42) | Power supply | Four distributed VCC pins reduce IR drop and improve noise immunity across wide bus structures |
| 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 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC16244ADGVR | Noninverting 16-bit buffer (unidirectional); no DIR pins; OE-only control | Suitable only for fixed-direction data paths (e.g., address latching), not bidirectional bus arbitration | Select when direction control is handled externally or unnecessary; lower pin count simplifies routing |
| SN74AVC16245DGVR | Higher speed (2.5 ns max tpd at 1.8 V); supports 1.2–3.6 V VCC; higher Ioff leakage (±20 µA) | Better suited for sub-1.8-V mobile SoC interconnects; less ideal for industrial 125°C environments due to tighter thermal limits | Prefer for battery-powered portable devices needing faster throughput; verify thermal derating above 85°C |
Compared with SN74LVC16245ADGVR, SN74LVC16244ADGVR removes bidirectional capability but reduces complexity for unidirectional use cases, while SN74AVC16245DGVR trades wider temperature margin for higher speed and lower-voltage operation-making each suitable for distinct system-level trade-offs.

FAQ
What is the maximum operating temperature for SN74LVC16245ADGVR?
The SN74LVC16245ADGVR is fully specified from –40°C to +125°C ambient temperature. This extended range is validated per JEDEC JESD78 and supports deployment in harsh environments such as industrial motor drives, telecom base stations, and automotive auxiliary control units where thermal management is constrained.
Does SN74LVC16245ADGVR support 5-V input signals when powered at 3.3 V?
Yes, SN74LVC16245ADGVR accepts input voltages up to 5.5 V regardless of VCC setting (1.65–3.6 V). This 5-V-tolerant input capability is explicitly characterized in the datasheet and enables direct connection to legacy 5-V peripherals without external level-shifting components.
How does the Ioff feature function in SN74LVC16245ADGVR?
The Ioff feature in SN74LVC16245ADGVR disables all outputs when VCC = 0 V, limiting input/output leakage to ±10 µA. This prevents damaging current backflow during live insertion, partial power-down, or board-level hot-swap events-critical for modular industrial and telecom systems.
What is the pin-compatible replacement for SN74LVC16245ADGVR in TSSOP package?
SN74LVC16245ADGGR is the TSSOP (DGG) variant of the same device, sharing identical logic, timing, and electrical specifications. It differs only in package dimensions (12.50 mm × 6.10 mm vs. 9.70 mm × 4.40 mm for TVSOP) and marking ("LVC16245A" vs. "LD245A"), with no functional or layout compatibility.
Can SN74LVC16245ADGVR be used as a single 16-bit transceiver or only as dual 8-bit units?
SN74LVC16245ADGVR can be configured either way: as one 16-bit transceiver (by tying 1DIR = 2DIR and 1OE = 2OE) or as two independent 8-bit transceivers (using separate DIR/OE controls). The datasheet's Function Table and Simplified Schematic confirm both operational modes are fully supported and characterized.
