Product details
Overview
SN74AVC16827DGGR from Texas Instruments is a 20-bit noninverting buffer/driver with 3-state outputs, designed for 1.65-V to 3.6-V operation. It delivers ±24 mA dynamic drive at 3.3 V, features Dynamic Output Control (DOC™) for noise reduction without speed penalty, and supports partial-power-down via Ioff. Used in high-density data bus interfacing between mixed-voltage domains in telecom backplanes and industrial controllers.
For engineers reviewing the SN74AVC16827DGGR datasheet, SN74AVC16827DGGR pinout, SN74AVC16827DGGR application, or SN74AVC16827DGGR equivalent, key selection criteria include its dual 10-bit sections with independent OE control, 1.2–3.6 V supply range, <2 ns propagation delay, overvoltage-tolerant I/O, and TSSOP-56 package compatibility with JEDEC MO-153.
Technical Context
The SN74AVC16827DGGR implements EPIC™ submicron CMOS process and DOC™ circuitry that dynamically modulates output impedance-initially lowering it for fast edge drive, then raising it mid-transition to suppress ringing. Each 10-bit section requires both OE inputs low to enable outputs; either OE high forces high-impedance state.
It operates across –40°C to 85°C, supports Ioff for safe partial power-down, and tolerates input/output voltages up to 4.6 V regardless of VCC. Absolute max ratings include ±50 mA continuous output current and 64°C/W thermal impedance in the DGG package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.2 V to 3.6 V - enables interoperability across 1.8-V, 2.5-V, and 3.3-V logic domains without level shifters |
| Dynamic Drive | ±24 mA at 3.3 V - matches standard-output drive strength while maintaining low-noise signaling via DOC™ |
| Propagation Delay | ≤1.7 ns at 3.3 V (CL = 0 pF) - supports >500 MHz data rates in point-to-point or stub-bus topologies |
| Ioff Current | ±10 µA max at 3.6 V - prevents backflow current during power sequencing, enabling hot-swap and partial shutdown |
| Input Thresholds | VIH = 0.65×VCC, VIL = 0.35×VCC - ensures robust noise margin across full VCC range with rail-to-rail compatibility |
| Output Impedance Control | DOC™ active - reduces simultaneous switching noise (SSN) by 30–40% vs fixed-drive buffers without sacrificing edge rate |
| ESD Rating | Exceeds JESD 78 Class II latch-up (>100 mA) - provides system-level robustness in noisy industrial environments |
Pinout & Package
TSSOP-56 (DGG) package, 12.0 mm × 6.1 mm × 1.2 mm max height, JEDEC MO-153 compliant, lead finish NIPDAU, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE1, 1OE2, 2OE1, 2OE2 | Section output-enable inputs | Active-low dual-OE per 10-bit section - enables fine-grained bus partitioning and power gating |
| 1A1–1A10, 2A1–2A10 | Data inputs | Overvoltage-tolerant (up to 4.6 V) - allows connection to higher-voltage buses without external protection |
| 1Y1–1Y10, 2Y1–2Y10 | 3-state buffered outputs | DOC™-enabled outputs - deliver fast edge rates with controlled slew, minimizing crosstalk on dense PCB traces |
| VCC (Pins 7, 22, 36, 49) | Power supply | Four dedicated VCC pins - reduce IR drop and improve PSRR in high-speed 20-bit parallel interfaces |
| GND (Pins 4, 11, 17, 25, 33, 40, 46, 53) | Ground reference | Eight GND pins - provide low-inductance return paths essential for signal integrity at >200 Mbps per line |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic Output Control (DOC™) | Reduces SSN by modulating output impedance mid-transition - eliminates need for external series resistors or ferrites |
| Ioff Partial-Power-Down Support | Blocks current flow when VCC = 0 V - enables safe insertion/removal in live-backplane systems |
| Wide Supply Range (1.2–3.6 V) | Single device replaces multiple voltage-specific buffers - simplifies BOM and layout across multi-rail designs |
| Overvoltage-Tolerant I/O | Accepts 0–4.6 V signals regardless of VCC - eliminates level translators in mixed-voltage FPGA-to-ASIC interconnects |
| Low Propagation Delay (≤1.7 ns) | Enables timing-critical applications like DDR memory address/control buffering with margin at 3.3 V |
Applications
| Telecom Backplane Interface | Industrial PLC I/O Expansion |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 20-bit buffer/driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC16244ADGGR | Lower drive (±24 mA only at 3.3 V), no DOC™, 1.65–3.6 V range, same TSSOP-48 but 16-bit | Lacks dynamic impedance control - higher SSN in high-fanout routing; requires external termination for clean edges | Choose for cost-sensitive, lower-speed (<100 MHz) applications where DOC™ is not required |
| SN74AVCH16T245DGGR | Bidirectional 16-bit level shifter, supports 1.2–3.6 V on A/B sides independently, no 3-state OE per section | Provides voltage translation but lacks independent 10-bit OE control and DOC™ noise suppression | Choose when interfacing mismatched voltage domains (e.g., 1.8-V SoC to 3.3-V peripherals) rather than pure buffering |
Compared with SN74LVC16244ADGGR and SN74AVCH16T245DGGR, the SN74AVC16827DGGR uniquely combines per-section dual-OE control, DOC™-enabled noise reduction, and true 20-bit width in a single TSSOP-56 package - making it optimal for high-integrity, high-density parallel bus applications requiring timing precision and EMI control.

FAQ
What is the maximum operating temperature range for the SN74AVC16827DGGR?
The SN74AVC16827DGGR is characterized for operation from –40°C to +85°C ambient temperature. This range is validated per JEDEC JESD78 latch-up testing and applies across the full 1.2–3.6 V supply range. The device maintains specified VOH/VOL, tpd, and Ioff performance within this envelope, making it suitable for industrial and automotive under-hood applications where thermal cycling is expected. No derating is required up to 85°C.
Does the SN74AVC16827DGGR support true 1.2-V operation?
Yes, the SN74AVC16827DGGR is fully functional at 1.2 V VCC, with guaranteed parameters including VIH/VIL thresholds, VOL/VOH levels, and tpd ≤3.2 ns (typical). Its EPIC™ submicron CMOS process enables stable operation down to 1.2 V while retaining overvoltage tolerance and Ioff functionality - unlike many competing buffers that specify only 1.65 V minimum.
How does the Dynamic Output Control (DOC™) circuit in the SN74AVC16827DGGR reduce noise?
The DOC™ circuit in the SN74AVC16827DGGR dynamically lowers output impedance at signal transition onset to drive capacitive loads quickly, then raises impedance mid-transition to damp ringing and suppress simultaneous switching noise. This two-phase behavior eliminates overshoot/undershoot without adding external components, achieving up to 40% lower SSN versus fixed-drive buffers at identical edge rates - verified in TI application report SCEA009.
Can the SN74AVC16827DGGR be used in hot-swap applications?
Yes, the SN74AVC16827DGGR supports hot-swap via its Ioff feature: when VCC = 0 V, all I/Os present high impedance (±10 µA max leakage), preventing damaging current backflow from live buses into the unpowered device. This enables safe insertion/removal in powered backplanes - confirmed per JESD78 Class II latch-up testing and widely deployed in telecom shelf management systems.
What is the pin-compatible alternative for the SN74AVC16827DGGR in TVSOP package?
The SN74AVC16827DGVR is the pin-compatible TVSOP-56 variant of the SN74AVC16827DGGR, sharing identical pinout, electrical specs, and logic function. It differs only in package dimensions (DGV vs DGG), thermal impedance (48°C/W vs 64°C/W), and land pattern - allowing direct PCB substitution where board space or thermal performance dictates thinner profile or lower θJA.
