Product details
Overview
SN74LVC828ADBR from Texas Instruments is a 10-bit inverting buffer/driver with dual 3-state enable (OE1/OE2) and 24-pin TSSOP package, operating from 1.65 V to 3.6 V, supporting 5-V-tolerant inputs and mixed-mode 3.3-V/5-V system interfacing in high-density data buses.
For engineers reviewing the SN74LVC828ADBR datasheet, SN74LVC828ADBR pinout, SN74LVC828ADBR application, or SN74LVC828ADBR equivalent, key selection criteria include its 3.3-V-compatible 10-bit bus driving capability, dual active-low 3-state control, Ioff partial-power-down support, and 6.7 ns max propagation delay at 3.3 V.
Technical Context
The SN74LVC828ADBR implements a dual-gated 3-state output architecture where either OE1 or OE2 high forces all ten Y outputs into high-impedance, enabling precise bus arbitration. Its input structure accepts voltages up to 5.5 V independent of VCC, allowing direct connection to legacy 5-V logic without level shifters.
It features Ioff circuitry that disables outputs during power-down to prevent backflow current, and meets JESD 17 latch-up immunity (>250 mA) and JESD 22 ESD ratings (2000-V HBM, 200-V MM, 1000-V CDM), making it suitable for hot-swap and mixed-voltage board designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 3.6 V - Enables operation across low-voltage portable and industrial 3.3-V systems. |
| Input Voltage Tolerance | Up to 5.5 V - Allows direct interfacing with 5-V CMOS/TTL sources without external level translation. |
| Max Propagation Delay | 6.7 ns at VCC = 3.3 V - Supports high-speed data path timing in wide parallel buses. |
| Output Drive Strength | ±24 mA at VCC = 3 V - Sustains robust signal integrity across loaded PCB traces and multiple fanouts. |
| Ioff Current | ±10 µA at VI/VO = 5.5 V - Ensures safe isolation during partial power-down or hot-insertion scenarios. |
| Logic Function | Inverting buffer - Outputs Y1–Y10 are logical complements of A1–A10, enabling polarity correction in bus paths. |
| ESD Protection | 2000-V HBM, 200-V MM, 1000-V CDM - Meets industrial-grade reliability requirements per JESD 22. |
Pinout & Package
TSSOP-24 (PW) package: 4.4 mm × 5.0 mm body, 0.65 mm pitch, 1.2 mm max height, lead-free NiPdAu finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 | A1–A10 Inputs | Non-inverting data inputs; accept 0–5.5 V regardless of VCC level. |
| 11, 12 | OE1, OE2 | Active-low 2-input AND gate enables - either high disables all outputs to high-Z. |
| 13 | GND | Ground reference for all internal circuitry and output drivers. |
| 14 | VCC | Core supply (1.65–3.6 V); powers logic and output stages. |
| 15–24 | Y1–Y10 Outputs | Inverting buffered outputs; each provides 3-state control and ±24 mA drive. |
Key Features
| Feature | Design Value |
|---|---|
| Mixed-mode voltage translation | 5-V-tolerant inputs with 3.3-V VCC enable seamless bridging between legacy and modern logic families. |
| Dual 3-state enable logic | Independent OE1/OE2 pins implement OR-ed disable control - simplifies bus arbitration in multi-driver systems. |
| Ioff partial-power-down protection | Prevents damaging current flow when VCC = 0 V but inputs/outputs remain biased, critical for hot-plug applications. |
| Low ground bounce / undershoot | Typical VOLP < 0.8 V and VOHV > 2 V at 3.3 V - maintains signal integrity during fast switching on shared power rails. |
| High noise immunity | VIH/VIL thresholds scale with VCC (e.g., VIH = 0.65×VCC min at 1.65 V) - ensures reliable operation across full supply range. |
Applications
| PCI Express Add-in Card Interface | Industrial PLC Backplane Buffering |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 10-bit inverting buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC827ADBR | Non-inverting output logic; identical pinout, VCC range, and drive strength. | Used where signal polarity must be preserved (e.g., clock distribution, non-inverted data latching). | Select SN74LVC827ADBR only if inversion is undesirable; otherwise SN74LVC828ADBR is optimal for polarity correction. |
| SN74ALVC16834DGGR | 16-bit, non-inverting, higher drive (±24 mA), same VCC range but 48-pin TSSOP package. | Targets wider buses requiring single-package 16-bit buffering; not pin-compatible. | Choose SN74ALVC16834DGGR only when 16-bit width is required; SN74LVC828ADBR remains preferred for 10-bit space-constrained layouts. |
Compared with SN74LVC827ADBR, SN74LVC828ADBR provides essential signal inversion for bus polarity alignment; compared with SN74ALVC16834DGGR, it delivers identical per-bit performance in half the footprint and pin count, optimizing PCB area and routing complexity for 10-bit interfaces.

FAQ
What is the function of OE1 and OE2 on the SN74LVC828ADBR?
OE1 and OE2 are active-low 3-state enable inputs configured as a 2-input AND gate: if either is high, all ten Y outputs enter high-impedance state. This allows flexible bus arbitration-e.g., OE1 can be tied to system reset while OE2 connects to a local controller, ensuring deterministic bus release timing. The SN74LVC828ADBR uses this dual-enable scheme to avoid bus conflicts during power-up or mode transitions.
Can the SN74LVC828ADBR safely interface a 5-V microcontroller to a 3.3-V FPGA?
Yes-the SN74LVC828ADBR accepts input voltages up to 5.5 V while operating at VCC = 3.3 V, enabling direct connection without external level shifters. Its 5-V-tolerant inputs and 3.3-V output swing meet both microcontroller input thresholds and FPGA I/O standards. The SN74LVC828ADBR also provides Ioff protection, preventing current backflow if the FPGA is powered down while the MCU remains active.
Does the SN74LVC828ADBR support hot-swap applications?
Yes-its Ioff specification (±10 µA at VI/VO = 5.5 V) actively disables outputs during power-down, eliminating damaging current flow when VCC is off but input/output nodes remain biased. Combined with 2000-V HBM ESD rating and latch-up immunity exceeding 250 mA, the SN74LVC828ADBR is qualified for hot-plug use in modular backplanes and field-replaceable units.
What is the maximum output drive capability of the SN74LVC828ADBR at 3.3 V?
At VCC = 3.3 V, the SN74LVC828ADBR delivers ±24 mA per output (IOL = 24 mA, IOH = –24 mA), verified per Electrical Characteristics table. This drive strength supports fanout to ≥10 LVC loads or driving 50-Ω transmission lines with minimal overshoot-critical for maintaining signal integrity in dense PCB layouts. The SN74LVC828ADBR maintains this rating across –40°C to 85°C.
Is the SN74LVC828ADBR pin-compatible with other 10-bit LVC buffers?
The SN74LVC828ADBR shares identical 24-pin TSSOP (PW) pinout with SN74LVC827ADBR (non-inverting version), enabling drop-in replacement where signal polarity is not constrained. However, it is not compatible with 16-bit or different-package variants (e.g., SOIC DW or TVSOP DGV). Always verify top-side marking (LC828A) and package drawing PW0024A when substituting the SN74LVC828ADBR.
