Product details
Overview
74LVTN16244BDGG,11 from Nexperia is a 3.3 V, 16-bit non-inverting buffer/driver with 3-state outputs, implemented in high-performance BiCMOS technology. It supports flexible partitioning as four 4-bit, two 8-bit, or one 16-bit bus interface, delivers ±32 mA/±64 mA drive strength, and operates across -40 °C to +85 °C for industrial backplane and memory address/data bus applications.
For engineers reviewing the 74LVTN16244BDGG,11 datasheet, 74LVTN16244BDGG,11 pinout, 74LVTN16244BDGG,11 application, or 74LVTN16244BDGG,11 equivalent, this device is selected for 3.3 V ↔ 5 V mixed-voltage system interfacing where TTL-compatible input thresholds, live insertion capability, and power-up 3-state behavior are required.
Technical Context
This device implements four independent 4-bit non-inverting buffer sections, each controlled by a dedicated active-low output enable (nOE) input. Each section drives four outputs with rail-to-rail voltage compatibility: inputs accept 0–5.5 V, outputs tolerate up to 7.0 V while sourcing/sinking defined currents.
Its BiCMOS architecture enables fast propagation delays (1.7–3.2 ns typical), low static current (≤0.12 mA with outputs disabled), and robust ESD protection (HBM >2000 V, CDM >1000 V), all while maintaining latch-up immunity per JESD78B Class II (>500 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 2.7 V to 3.6 V - ensures stable operation under 3.3 V nominal rail with ±0.3 V tolerance. |
| IOH / IOL | -32 mA / +64 mA - supports driving heavy capacitive loads or multiple TTL inputs without signal degradation. |
| tPLH / tPHL | 0.5–3.2 ns - enables high-speed data transfer in 100+ MHz bus systems with tight timing margins. |
| VIL / VIH | ≤0.8 V / ≥2.0 V - guarantees reliable logic-level recognition when interfacing with both 3.3 V and 5 V CMOS/TTL sources. |
| Operating Temp | -40 °C to +85 °C - validated for industrial-grade reliability in uncontrolled ambient environments. |
| ESD Rating | HBM >2000 V, CDM >1000 V - reduces risk of field failure during handling and board assembly. |
| Power-up State | Outputs in 3-state - prevents bus contention at power-on before control logic initializes. |
Pinout & Package
TSSOP48 package (SOT362-1), plastic thin shrink small outline, 48 leads, body width 6.1 mm, lead pitch 0.5 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE, 3OE, 4OE (Pins 1, 48, 25, 24) | Active-low output enable | Independent control per 4-bit section; asserts 3-state when HIGH, enables drive when LOW. |
| 1A0–1A3, 2A0–2A3, 3A0–3A3, 4A0–4A3 (Pins 47,46,44,43; 41,40,38,37; 36,35,33,32; 30,29,27,26) | Data inputs | Non-inverting inputs accepting TTL/CMOS levels; tolerant to 5.5 V regardless of VCC. |
| 1Y0–1Y3, 2Y0–2Y3, 3Y0–3Y3, 4Y0–4Y3 (Pins 2,3,5,6; 8,9,11,12; 13,14,16,17; 19,20,22,23) | Data outputs | 3-state buffered outputs capable of sinking 64 mA or sourcing 32 mA; tolerate 7.0 V in OFF-state. |
| VCC (Pins 7, 18, 31, 42) | Supply voltage | Four distributed power pins reduce IR drop and improve noise immunity on high-speed buses. |
| GND (Pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight ground pins provide low-inductance return paths essential for signal integrity at >50 MHz. |
Key Features
| Feature | Design Value |
|---|---|
| Live insertion/extraction support | Enables hot-swap module replacement in backplane systems without powering down the host. |
| No bus current loading at 5 V | Output clamps safely when tied to 5 V bus, eliminating need for external pull-ups or level shifters. |
| Power-up 3-state | Guarantees outputs remain high-impedance until VCC stabilizes, preventing startup glitches or contention. |
| Latch-up immunity >500 mA | Meets JESD78B Class II - eliminates risk of destructive latch-up under transient overvoltage conditions. |
| Input/output voltage tolerance | Accepts 0–5.5 V inputs and withstands 0–7.0 V at outputs - simplifies mixed-supply interconnect design. |
Applications
| Backplane Bus Interface | Memory Address Buffering |
|---|---|
Use Scenario: Interfacing a 3.3 V FPGA or ASIC to a legacy 5 V parallel bus in telecom line cards. IC Role / Device Role / Timing Role: Level-translating, non-inverting buffer with independent 4-bit enables for segmented bus control. Use Value: Eliminates discrete level shifters; maintains <3.2 ns propagation delay while tolerating 5 V bus voltages without damage. |
Use Scenario: Driving 16-bit address lines from a microcontroller to SRAM or Flash memory in industrial PLCs. IC Role / Device Role / Timing Role: High-drive-strength address driver ensuring clean edge integrity across long PCB traces. Use Value: Sinks 64 mA per output to overcome trace capacitance and maintain setup/hold timing at 20+ MHz clock rates. |
| Hot-Swappable Module I/O | Legacy System Upgrade Interface |
Use Scenario: Providing isolated I/O buffering between a hot-pluggable mezzanine card and main system backplane. IC Role / Device Role / Timing Role: 3-state bus transceiver enabling safe insertion/removal without disrupting active bus traffic. Use Value: Power-up 3-state and live-insertion rating prevent bus contention or data corruption during module swap. |
Use Scenario: Upgrading a 5 V CPU-based system with modern 3.3 V peripherals while retaining original bus architecture. IC Role / Device Role / Timing Role: Bidirectional voltage-tolerant interface buffer bridging supply domain boundaries. Use Value: Accepts 5 V inputs and drives 3.3 V loads directly - avoids redesign of existing 5 V logic layers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit non-inverting buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC16244ADGGR | Lower drive (±24 mA), 1.65–3.6 V VCC range, no 5 V-tolerant inputs | Suitable only for pure 3.3 V systems; cannot interface directly to 5 V buses | Select when cost and power efficiency outweigh mixed-voltage interface needs. |
| 74ALVCH16244PW,118 | Higher speed (tPD ≤1.9 ns), same 3.3 V supply, but only 3.6 V max input tolerance | Lacks 5 V bus tolerance and live insertion rating; requires external protection for hot-swap use | Prefer for high-frequency timing-critical designs where 5 V interfacing is not required. |
Compared with SN74LVC16244ADGGR and 74ALVCH16244PW,118, the 74LVTN16244BDGG,11 uniquely combines 5 V-tolerant inputs, 7 V-tolerant outputs, live insertion support, and ±64 mA sink capability - making it the only choice for robust 3.3 V/5 V bus bridging in industrial backplanes.

FAQ
Can 74LVTN16244BDGG,11 safely drive a 5 V bus while powered at 3.3 V?
Yes. Its outputs tolerate up to 7.0 V in the OFF-state and its inputs accept 0–5.5 V regardless of VCC. When enabled, outputs swing rail-to-rail (0 V to 3.3 V) but remain undamaged if externally pulled to 5 V - enabling direct connection to 5 V buses without clamping diodes or resistors.
What is the maximum capacitive load this device can drive at 20 MHz?
Based on dynamic characteristics and output drive strength, it reliably drives ≤50 pF loads at 20 MHz while maintaining <3.2 ns propagation delay and <4.5 ns 3-state transition times. For heavier loads, derate frequency or add series termination to limit ringing and overshoot.
Does this part support hot-swap in powered-backplane systems?
Yes. It is explicitly rated for live insertion and extraction per datasheet Section 2, supported by power-up 3-state behavior, latch-up immunity >500 mA, and ESD protection exceeding 2000 V HBM - all critical for hot-swap reliability in telecom and industrial chassis.
How many ground pins does the TSSOP48 package have, and why does it matter?
The DGG package has eight GND pins (Pins 4, 10, 15, 21, 28, 34, 39, 45). This distributed grounding minimizes ground bounce and improves signal integrity for high-speed 16-bit buses, especially under simultaneous switching output (SSO) conditions common in memory and address buffering.
