Product details
Overview
74ALVCH16825DGG:11 from Nexperia is an 18-bit non-inverting bus buffer/driver with 3-state outputs, dual 9-bit sections, independent active-LOW output enables (1OE1/1OE2 and 2OE1/2OE2), bus hold on all data inputs, and operation across 1.2 V to 3.6 V supply. It supports high-speed data routing in memory address/data buses and backplane interfaces where signal integrity and floating-input immunity are critical.
For engineers reviewing the 74ALVCH16825DGG:11 datasheet, 74ALVCH16825DGG:11 pinout, 74ALVCH16825DGG:11 application, or 74ALVCH16825DGG:11 equivalent, this page delivers verified electrical specs, TSSOP56 package layout, bus hold behavior, propagation delay (≤3.4 ns at 3.3 V), and real-world use cases in industrial control and telecom backplanes.
Technical Context
The device implements two independent 9-bit non-inverting buffer sections, each requiring both OE inputs LOW to enable outputs; either OE HIGH forces that section into high-impedance state. Bus hold circuitry actively maintains unused inputs at valid logic levels without external resistors.
It operates from −40 °C to +85 °C with supply voltage ranging 1.2 V–3.6 V, supports direct TTL-level interfacing, and features low-inductance multiple VCC/GND pins to suppress ground bounce and noise in dense PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 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. |
| Propagation Delay | ≤3.4 ns at VCC = 3.0–3.6 V - Supports >200 MHz bus timing in high-speed address/data paths. |
| Output Drive | ±24 mA at VCC = 3.0 V - Drives 50 Ω transmission lines directly at 85 °C, eliminating need for external line drivers. |
| Bus Hold Current | IBHL = 75–150 μA at VI = 0.8 V (VCC = 3.0 V) - Maintains stable logic states on unconnected inputs without pull resistors. |
| Operating Temperature | −40 °C to +85 °C - Qualified for industrial-grade embedded systems and telecom infrastructure equipment. |
| ESD Robustness | HBM >2000 V, CDM >1000 V - Reduces susceptibility to handling damage during assembly and field operation. |
| Power Dissipation | Ptot ≤ 500 mW - Allows thermal design margin in compact TSSOP56 packages with up to 12 GND/VCC pins. |
Pinout & Package
TSSOP56 (SOT364-1) package: plastic thin shrink small outline, 56 leads, 6.1 mm body width, 0.5 mm lead pitch, 1.2 mm max height. Features 12 dedicated GND and 4 VCC pins for low-noise power distribution.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A0–1A8, 2A0–2A8 | Data input (18 total) | Non-inverting inputs for respective 9-bit sections; all include bus hold circuitry. |
| 1Y0–1Y8, 2Y0–2Y8 | Data output (18 total) | 3-state outputs enabled only when both corresponding OE pins are LOW. |
| 1OE1, 1OE2, 2OE1, 2OE2 | Output enable (active-LOW) | Each 9-bit section requires both OE signals LOW to drive outputs; single HIGH disables entire section. |
| GND (pins 4, 11, 14, 15, 18, 25, 32, 39, 42, 43, 46, 53) | Ground reference | 12 distributed GND pins minimize ground loop inductance and reduce switching noise. |
| VCC (pins 7, 22, 35, 50) | Supply voltage | 4 distributed VCC pins ensure uniform power delivery and lower impedance supply path. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range | 1.2 V–3.6 V operation enables drop-in replacement across 1.8 V, 2.5 V, and 3.3 V systems without redesign. |
| MULTIBYTE™ flow-through pinout | Input/output pairs aligned on opposite sides of TSSOP56 simplify PCB routing and reduce trace crosstalk. |
| Integrated bus hold | Eliminates need for 18 external pull-up/down resistors, reducing BOM count and board area in bus termination. |
| Low ground bounce | 12 GND pins and symmetric VCC distribution limit ΔI/Δt-induced noise during simultaneous 18-bit switching. |
| TTL-compatible interface | Accepts standard TTL input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 3.0 V) for legacy system integration. |
Applications
| Industrial PLC Backplane Interface | Telecom Line Card Data Buffering |
|---|---|
Use Scenario: Isolating and driving parallel address/data buses between CPU module and I/O expansion slots in programmable logic controllers. IC Role / Device Role / Timing Role: Non-inverting 18-bit buffer with 3-state control synchronizes bus access across multiple modules while preventing contention. Use Value: Bus hold maintains valid logic on unselected slots; <3.4 ns propagation delay ensures setup/hold timing compliance at 25 MHz bus clock. |
Use Scenario: Driving high-capacitance backplane traces (≥30 pF) between FPGA-based packet processors and PHY transceivers in modular line cards. IC Role / Device Role / Timing Role: 3-state driver provides clean signal launch onto 50 Ω controlled-impedance traces with minimal overshoot. Use Value: ±24 mA drive strength sustains signal integrity over 15 cm backplane runs; 12-GND pin layout suppresses simultaneous switching noise. |
| Automated Test Equipment (ATE) Signal Routing | Medical Imaging Data Acquisition Interface |
Use Scenario: Multiplexing digital stimulus/response signals between test head and DUT in high-channel-count ATE systems. IC Role / Device Role / Timing Role: Dual-section 3-state buffer enables dynamic bus partitioning-each 9-bit section independently gated for channel grouping. Use Value: Independent OE pairs (1OE1/1OE2, 2OE1/2OE2) allow fine-grained control of signal routing without full-bus reconfiguration delays. |
Use Scenario: Interfacing ADC output buses (16–18 bit parallel) to FPGA-based image processing engines in portable ultrasound systems. IC Role / Device Role / Timing Role: Level-translating buffer adapts 1.8 V ADC outputs to 3.3 V FPGA inputs while holding floating lines during acquisition idle periods. Use Value: 1.2 V–3.6 V supply range supports mixed-voltage domain bridging; bus hold prevents metastability during sensor sleep/wake transitions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 18-bit 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ALVTH16825DGGR | TI part with identical 18-bit dual-section architecture but higher drive (±32 mA) and wider temp range (−40 °C to +125 °C); no bus hold. | Requires external pull resistors on unused inputs; better suited for extended-temp automotive diagnostics tools. | Select if higher drive or extended temperature is required and bus hold is not needed. |
| 74LVC16245ADGG:11 | Nexperia LVC variant: same TSSOP56 package and pinout, but only 16-bit, no bus hold, lower drive (±24 mA at 3.3 V), and narrower VCC range (1.65 V–3.6 V). | Lacks dual-OE per section and bus hold; suitable only for simpler 16-bit bidirectional applications without floating-input risk. | Select only for cost-sensitive 16-bit designs where bus hold and 18-bit width are unnecessary. |
Compared with SN74ALVTH16825DGGR, the 74ALVCH16825DGG:11 trades extended temperature and higher drive for integrated bus hold-critical for reliability in industrial backplanes with intermittent connections. Versus 74LVC16245ADGG:11, it adds 2 bits, dual-OE control per section, and bus hold at identical package size, enabling more robust 18-bit bus isolation.

FAQ
What is the minimum supply voltage for guaranteed operation?
The 74ALVCH16825DGG:11 is fully specified down to 1.2 V per JEDEC JESD8-7, with static and dynamic parameters validated across 1.2 V–3.6 V. Below 1.2 V, functionality is not guaranteed and bus hold current drops significantly.
How does the dual-output-enable logic work per 9-bit section?
For Section 1 (1A0–1A8 → 1Y0–1Y8), both 1OE1 and 1OE2 must be LOW to enable outputs; if either is HIGH, all nine outputs go high-impedance. Section 2 (2A0–2A8 → 2Y0–2Y8) follows identical logic with 2OE1 and 2OE2.
Can this device replace a 74LVC16245 in an existing design?
No-pinout differs: 74LVC16245 is bidirectional with direction control (DIR), while 74ALVCH16825DGG:11 is unidirectional with dual active-LOW OE per section. Also, it has 18 bits vs. 16, different bus hold presence, and distinct timing specs.
Is the TSSOP56 package RoHS-compliant and lead-free?
Yes-the SOT364-1 package used for 74ALVCH16825DGG:11 is lead-free, RoHS-compliant, and halogen-free per Nexperia's product compliance documentation dated July 2024.
