Product details
Overview
SN74LVCR16245ADGVR 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-V to 3.6-V buses. It supports mixed-mode signaling (5.5-V-tolerant inputs at 3.3-V VCC), delivers 4.8 ns max propagation delay at 3.3 V, and integrates 26-Ω series output resistors to suppress switching noise-used in server backplanes and telecom line cards.
For engineers reviewing the SN74LVCR16245ADGVR datasheet, SN74LVCR16245ADGVR pinout, SN74LVCR16245ADGVR application, or SN74LVCR16245ADGVR equivalent, key selection criteria include Ioff-enabled live insertion support, 5.5-V input tolerance for 3.3-V systems, dual independent DIR/OE control per 8-bit section, and TVSOP-48 package compatibility with high-density PCB layouts.
Technical Context
The SN74LVCR16245ADGVR implements two independent 8-bit transceiver sections, each with dedicated direction (DIR) and output-enable (OE) controls. Its logic-level translation capability stems from overvoltage-tolerant inputs that accept up to 5.5 V regardless of VCC (1.65–3.6 V), enabling seamless interfacing between 3.3-V logic and legacy 5-V peripherals.
Each I/O port features integrated 26-Ω series termination to dampen edge rates and reduce ground bounce (VOLP < 0.8 V) and VOH undershoot (VOHV > 2 V) at 3.3 V. The device supports partial-power-down operation via Ioff, blocking current flow when VCC = 0 V, and includes active bus-hold circuitry on all data inputs to maintain valid logic states during idle conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 3.6 V - Enables operation across low-voltage embedded and industrial supply rails. |

Pinout & Package
SN74LVCR16245ADGVR uses a 48-pin TVSOP (DGV) package measuring 9.70 mm × 4.40 mm, optimized for high-density routing and thermal performance (RθJA = 78.4°C/W). Pin numbering follows standard DGG/DGV/DL top-view layout with dual GND/VCC pairs distributed across the perimeter for low-inductance power delivery.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input | Determines data flow direction per 8-bit section: DIR = L enables B→A; DIR = H enables A→B. |
| 1OE, 2OE | Output enable input | Active-low control: OE = L enables outputs; OE = H places both A/B ports in high-impedance state. |
| 1A1–1A8, 2A1–2A8 | Data input/output (A-side) | 8-bit bidirectional port A; internally connected to transceiver core with bus-hold and 26-Ω series resistance. |
| 1B1–1B8, 2B1–2B8 | Data input/output (B-side) | 8-bit bidirectional port B; electrically identical to A-side with independent DIR/OE control. |
| VCC (Pins 7, 18, 31, 42) | Power supply | Four distributed VCC pins minimize IR drop and improve noise immunity across wide operating voltage range. |
| GND (Pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight GND pins provide low-impedance return paths and reduce ground bounce in high-speed switching. |
Key Features
| Feature | Design Value |
|---|---|
| Mixed-mode signal operation | 5.5-V-tolerant inputs allow direct interfacing between 3.3-V logic domains and 5-V peripherals without external translators. |
| Integrated 26-Ω series termination | Eliminates need for external series resistors on all I/O lines, reducing BOM count and PCB area while controlling edge rates. |
| Ioff partial-power-down support | Enables safe live insertion into powered-backplane systems by blocking current flow when VCC = 0 V. |
| Active bus-hold circuitry | Maintains valid logic levels on unused or undriven A/B port inputs, preventing floating nodes and system instability. |
| Low ground bounce (VOLP) | Typical VOLP < 0.8 V at 3.3 V ensures reliable low-level signaling integrity in noise-sensitive applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC16245A | No Ioff support; 5-V input tolerance only up to VCC + 0.5 V (not 5.5 V absolute). | Lacks live-insertion capability; unsuitable for hot-swap backplanes requiring zero-VCC isolation. | Select SN74LVCR16245ADGVR when Ioff and absolute 5.5-V input tolerance are required. |
| SN74AVC16245 | Lower VCC range (1.2–3.6 V); higher speed (3.2 ns tpd at 2.5 V); no integrated 26-Ω resistors. | Requires external series termination; optimized for ultra-low-voltage mobile SoC interconnects, not industrial backplanes. | Choose SN74LVCR16245ADGVR for robust 5.5-V tolerant operation and built-in noise suppression in fixed-logic systems. |
Compared with SN74LVC16245A and SN74AVC16245, the SN74LVCR16245ADGVR uniquely combines 5.5-V absolute input tolerance, Ioff-enabled live insertion, and integrated 26-Ω termination-making it the only option qualified for hot-swap server backplanes and mixed-voltage industrial control systems without external components.

FAQ
What is the maximum input voltage the SN74LVCR16245ADGVR can tolerate?
The SN74LVCR16245ADGVR accepts input voltages up to 5.5 V across its entire valid VCC range (1.65 V to 3.6 V), enabling direct interfacing with 5-V logic without level-shifting circuitry. This absolute 5.5-V tolerance-distinct from relative VCC+0.5 V limits found in standard LVC devices-is confirmed in Section 7.1 Absolute Maximum Ratings and Section 9.3 Feature Description of the SCES427B datasheet.
Does the SN74LVCR16245ADGVR support hot-swap or live insertion?
Yes, the SN74LVCR16245ADGVR supports live insertion via its Ioff feature, which disables outputs and blocks current flow when VCC = 0 V. This is explicitly documented in Section 3 Features ("Ioff Supports Live Insertion, Partial-Power-Down Mode, and Back-Drive Protection") and Section 9.3 Feature Description, making SN74LVCR16245ADGVR suitable for hot-pluggable server and telecom modules.
What package type is used by the SN74LVCR16245ADGVR?
The SN74LVCR16245ADGVR uses a 48-pin TVSOP (Thin Very Small Outline Package) with body size 9.70 mm × 4.40 mm, designated as DGV in TI's packaging nomenclature. This is confirmed in the Package Option Addendum (page 13) and Mechanical Data (MPDS006C), where DGV is specified as the sole package for SN74LVCR16245ADGVR orderable part numbers.
How does the SN74LVCR16245ADGVR handle unused inputs?
The SN74LVCR16245ADGVR includes active bus-hold circuitry on all A- and B-port data inputs, automatically holding unused or undriven pins at valid logic states. This is stated in Section 3 Features and Section 9.1 Overview, eliminating the need for external pull-up/down resistors and preventing floating-node-induced system instability.
What is the propagation delay specification for the SN74LVCR16245ADGVR at 3.3 V?
The SN74LVCR16245ADGVR has a maximum propagation delay (tpd) of 4.8 ns at VCC = 3.3 V, as specified in Section 3 Features and Table 7-6 Switching Characteristics. This value is measured under standard load conditions (CL = 50 pF, ∆V = ±0.3 V) and applies to both A→B and B→A data paths.
