Product details
Overview
74ALVT16827DGG,112 from NXP Semiconductors (formerly Philips) is a 20-bit non-inverting 3-state buffer/line driver optimized for high-speed bus interface applications in 2.5 V or 3.3 V systems with 5 V I/O tolerance. It delivers propagation delays as low as 0.7 ns (VCC = 3.3 V), ±64 mA output drive capability, and integrated bus-hold inputs eliminating external pull-ups. It is used in wide data/address path buffering for telecom backplanes and industrial control backplanes.
For engineers reviewing the 74ALVT16827DGG,112 datasheet, 74ALVT16827DGG,112 pinout, 74ALVT16827DGG,112 application, or 74ALVT16827DGG,112 equivalent, key selection criteria include 3-state enable timing (tPZH ≤ 3.8 ns), dual active-low output enables (1OE0/1OE1 and 2OE0/2OE1), bus-hold input current (±130 µA at VCC = 3 V), and TSSOP56 package compatibility with high-density PCB layouts.
Technical Context
The 74ALVT16827DGG,112 implements two independent 10-bit non-inverting buffer banks (Bank 1: pins 1A0–1A9 → 1Y0–1Y9; Bank 2: 2A0–2A9 → 2Y0–2Y9), each controlled by dedicated NOR-gated output enables (1OE0/1OE1 and 2OE0/2OE1). Its BiCMOS architecture enables simultaneous low static current (ICC ≤ 70 µA, VCC = 3.3 V, outputs disabled) and high dynamic drive (−32 mA sink / +64 mA source).
It supports live insertion/extraction and operates across −40 °C to +85 °C with 5 V-tolerant I/Os, latch-up immunity >500 mA per JESD78, and ESD protection exceeding 2000 V (MIL-STD-883) and 200 V (machine model). Bus-hold circuitry maintains valid logic states on unused inputs without external resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.3 V to 3.6 V - Supports dual-supply system interoperability and low-power operation. |
| Propagation Delay (tPLH/tPHL) | 0.7–2.3 ns @ CL = 50 pF - Enables sub-500 MHz bus clocking with deterministic timing margins. |
| Output Drive | +64 mA source / −32 mA sink - Drives heavy capacitive loads (e.g., multi-drop buses) without signal degradation. |
| Bus-Hold Current | ±130 µA @ VCC = 3 V - Maintains stable logic levels on floating inputs, removing need for 10 kΩ pull-up/down resistors. |
| I/O Voltage Tolerance | 0 V to 5.5 V - Allows safe interfacing with legacy 5 V logic while powered from 2.5 V or 3.3 V rails. |
| 3-State Enable Timing | tPZH ≤ 3.8 ns, tPLZ ≤ 3.8 ns - Ensures fast, glitch-free bus arbitration in time-critical multiplexed systems. |
| Input Capacitance (CI) | 3 pF - Minimizes loading on upstream drivers and preserves signal integrity at high frequencies. |
| Quiescent Supply Current | 70 µA @ VCC = 3.3 V, outputs disabled - Reduces standby power in always-on subsystems. |
Pinout & Package
TSSOP56 plastic thin shrink small outline package (SOT364-1), 56-pin, body width 6.1 mm, lead pitch 0.5 mm, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE0, 1OE1, 2OE0, 2OE1 | Active-low output enable inputs | NOR logic enables - Either OE must be LOW to activate corresponding 10-bit bank; enables fine-grained bus partitioning. |
| 1A0–1A9, 2A0–2A9 | Data inputs | 20 total inputs with bus-hold - Eliminates external biasing; prevents floating states during hot-swap or partial initialization. |
| 1Y0–1Y9, 2Y0–2Y9 | Non-inverting buffered outputs | 20 high-drive outputs - Each provides rail-to-rail swing and supports 5 V-tolerant signaling regardless of VCC. |
| VCC (pins 7, 22, 35, 50) | Positive supply | Multiple VCC pins - Reduce switching noise and IR drop across high-current transients. |
| GND (pins 4, 11, 18, 25, 32, 39, 46, 53) | Ground reference | Eight GND pins - Provide low-inductance return paths for all 20 outputs and internal logic, minimizing ground bounce. |
Key Features
| Feature | Design Value |
|---|---|
| 5 V I/O compatible | Inputs and outputs tolerate up to 5.5 V - Enables seamless integration into mixed-voltage systems without level shifters. |
| Power-up 3-state | Outputs remain high-impedance until VCC stabilizes - Prevents bus contention during power sequencing. |
| Live insertion/extraction support | Withstands hot-plug events without latch-up or damage - Critical for modular telecom and server backplane designs. |
| Latch-up protection | JESD78 compliant (>500 mA) - Guarantees robustness against transient-induced parasitic thyristor activation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 20-bit non-inverting 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ALVC16835DGGR | Lower drive (±24 mA), no bus-hold, 1.65–3.6 V VCC only - lacks 5 V I/O tolerance. | Suitable only in fully 3.3 V systems without legacy 5 V interfaces. | Select when cost and power are prioritized over voltage flexibility and bus stability. |
| 74LVT162244ADGG,112 | Same pinout and function but LVT family - higher ICC (120 µA vs. 70 µA), no bus-hold, lower drive (+32 mA/−32 mA). | Acceptable where lower drive and no bus-hold are acceptable, e.g., short-trace embedded buses. | Choose if existing LVT-based designs require drop-in replacement with identical timing behavior. |
Compared with SN74ALVC16835DGGR and 74LVT162244ADGG,112, the 74ALVT16827DGG,112 uniquely combines 5 V I/O tolerance, bus-hold inputs, and +64 mA sourcing - making it optimal for mixed-voltage, high-reliability backplane and industrial bus applications where signal integrity and robustness are critical.

FAQ
What is the maximum operating frequency supported by the 74ALVT16827DGG,112?
The 74ALVT16827DGG,112 does not specify a maximum clock frequency directly, but its propagation delay (tPLH/tPHL) of 0.7–2.3 ns at CL = 50 pF implies reliable operation up to ≥400 MHz for single-cycle bus transfers. System-level timing depends on trace length, load capacitance, and termination - actual usable frequency must be validated per board layout using the device's published AC waveforms and enable/disable timing parameters.
Does the 74ALVT16827DGG,112 require external pull-up or pull-down resistors on unused inputs?
No. The 74ALVT16827DGG,112 integrates bus-hold circuitry on all data inputs (1A0–1A9 and 2A0–2A9), providing ±130 µA overdrive current to maintain valid logic states without external resistors. This feature eliminates BOM cost and board space for pull-ups, simplifies design, and improves reliability during partial initialization or hot-swap events.
Can the 74ALVT16827DGG,112 be safely operated with a 2.5 V supply while interfacing with 5 V logic signals?
Yes. The 74ALVT16827DGG,112 is explicitly designed for 2.5 V or 3.3 V VCC operation with full 5 V I/O tolerance (VI and VO rated to 5.5 V). Inputs accept 0–5.5 V regardless of VCC, and outputs drive to near-rail levels compatible with 5 V CMOS thresholds - enabling direct connection to legacy 5 V devices without level shifters.
What is the purpose of the four output enable pins (1OE0, 1OE1, 2OE0, 2OE1) on the 74ALVT16827DGG,112?
The 74ALVT16827DGG,112 uses NOR-gated enable logic: each 10-bit bank (Bank 1: 1A/1Y; Bank 2: 2A/2Y) requires *both* of its paired OE pins (e.g., 1OE0 AND 1OE1) to be LOW for output activation. This dual-OE structure enhances noise immunity and allows flexible control schemes - such as enabling one bank while holding the other in high-Z using separate system control signals.
Is the 74ALVT16827DGG,112 suitable for hot-swap applications?
Yes. The 74ALVT16827DGG,112 is explicitly qualified for live insertion and extraction per manufacturer specifications. Its latch-up immunity (>500 mA), robust ESD protection (2000 V HBM), and power-up 3-state behavior ensure safe operation during hot-plug events in modular systems like telecom line cards and server blades - provided proper board-level current limiting and sequencing are implemented.
