Product details
Overview
74LVT16244BDGG,518 from Nexperia is a 3.3 V, 16-bit non-inverting 3-state buffer/driver in TSSOP48 package, featuring four independent output-enable inputs (1OE–4OE), bus-hold inputs eliminating external pull-ups, and ±32 mA/±64 mA drive capability. It operates from 2.7 V to 3.6 V, supports 5.5 V-tolerant inputs, and is used in high-speed backplane and memory interface buffering.
For engineers reviewing the 74LVT16244BDGG,518 datasheet, 74LVT16244BDGG,518 pinout, 74LVT16244BDGG,518 application, or 74LVT16244BDGG,518 equivalent, key selection factors include its 3.2 ns max propagation delay at 3.3 V, IOFF power-down protection, -40 °C to +85 °C industrial temperature range, and compatibility with TTL-level signaling without level shifters.
Technical Context
This BiCMOS device implements four independent 4-bit buffer sections, each controlled by a dedicated active-low output enable (nOE). Each section buffers data from four A-inputs (e.g., 1A0–1A3) to corresponding Y-outputs (e.g., 1Y0–1Y3) with rail-to-rail 3-state control.
Bus-hold circuitry maintains valid logic states on unused inputs without external resistors, while IOFF functionality disables output leakage when VCC = 0 V. Input overvoltage tolerance up to 5.5 V enables safe interfacing with 5 V buses in mixed-voltage systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7 V to 3.6 V - Ensures stable operation across wide industrial supply rails including noisy 3.3 V domains. |
| Input Voltage Range | 0 V to 5.5 V - Allows direct connection to 5 V logic without clamping diodes or level translators. |
| Output Drive | +64 mA sink / -32 mA source - Supports driving heavy capacitive loads (e.g., >50 pF) and multiple TTL inputs. |
| Propagation Delay | 1.8 ns typical (tPLH/tPHL at VCC = 3.3 V) - Enables reliable operation in >250 MHz data paths with margin. |
| Bus Hold Current | ±75 μA to ±135 μA - Actively retains input state during floating conditions, preventing metastability. |
| IOFF Leakage | ±100 μA at VCC = 0 V - Permits live insertion/extraction and partial power-down without bus contention. |
| Operating Temperature | -40 °C to +85 °C - Qualified for industrial-grade embedded control and communications equipment. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 24, 25, 48 | 1OE, 3OE, 4OE, 2OE | Active-low output enables - Independently disable each 4-bit buffer group to isolate bus segments. |

| 43–44, 46–47, 32–33, 35–36, 37–38, 40–41, 26–27, 29–30 | 1A0–1A3, 2A0–2A3, 3A0–3A3, 4A0–4A3 | Data inputs with bus hold - Maintain last-valid logic state when unconnected, eliminating need for external pull resistors. |
Key Features
| Feature | Design Value |
|---|---|
| Four independent 3-state control inputs | Enables selective isolation of four 4-bit data lanes-critical for multi-drop bus arbitration and hot-swap partitioning. |
| Bus-hold inputs | Eliminates external pull-up/pull-down resistors on unused inputs, reducing BOM count and PCB area in space-constrained designs. |
| IOFF partial power-down | Prevents current flow through powered-off outputs when VCC = 0 V-essential for live insertion in modular backplanes. |
| 5.5 V tolerant inputs | Permits direct interfacing with legacy 5 V logic families without voltage translation, simplifying mixed-supply system integration. |
| BiCMOS process | Combines bipolar speed and CMOS low static power-delivers 3.2 ns max propagation delay with sub-120 μA ICC supply current. |
Applications
| Memory Interface Buffering | Backplane Data Distribution |
|---|---|
Use Scenario: Driving address/data lines between FPGA and parallel NOR flash or SRAM in industrial controllers. IC Role / Device Role / Timing Role: Non-inverting 3-state buffer providing level-shifted, high-drive signal conditioning with precise timing control. Use Value: 1.8 ns typical propagation delay ensures setup/hold compliance at 100+ MHz bus speeds; bus-hold prevents floating inputs during reset or standby. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC16244ADGGR | Lower drive (±24 mA), 1.65–3.6 V supply, no bus hold, no IOFF | Suitable only for low-capacitance, single-supply 3.3 V systems without hot-swap requirements | Select when cost sensitivity outweighs drive strength and mixed-voltage robustness. |
| 74ALVCH16244TTR | Higher speed (1.5 ns typ), 2.3–3.6 V supply, bus hold, no IOFF, different pinout | Requires PCB redesign; lacks live-insertion support but offers tighter timing margins | Choose for ultra-low-latency interconnect where thermal/power trade-offs favor ALVC performance. |
Compared with SN74LVC16244ADGGR and 74ALVCH16244TTR, the 74LVT16244BDGG,518 uniquely balances 5.5 V input tolerance, IOFF-enabled hot-swap, and ±64 mA drive-making it optimal for ruggedized industrial backplanes where reliability trumps marginal speed gains.

FAQ
What is the maximum clock frequency supported by the 74LVT16244BDGG,518?
The device does not operate on a clock; it is an asynchronous buffer. Its 3.2 ns maximum propagation delay (tPLH/tPHL at VCC = 3.3 V) supports reliable data transfer in systems with signal periods ≥ 6.4 ns-equivalent to a 156 MHz toggle rate under ideal loading. Actual usable frequency depends on bus capacitance and drive strength requirements.
Can the 74LVT16244BDGG,518 be used with a 5 V microcontroller driving its inputs?
Yes. Inputs are overvoltage tolerant up to 5.5 V regardless of VCC level (2.7–3.6 V), allowing direct connection to 5 V microcontrollers without level shifters. The internal clamp structure safely sinks excess current, and bus-hold functionality maintains valid logic states even if the MCU is in reset or tri-stated.
Does the 74LVT16244BDGG,518 support hot-plug insertion into a live backplane?
Yes. It supports live insertion and extraction per datasheet Section 2, enabled by IOFF circuitry that disables output leakage when VCC = 0 V, and robust ESD protection (HBM > 2000 V, CDM > 1000 V). This prevents bus contention and damage during module replacement in powered systems.
How many ground and power pins does the TSSOP48 package have, and why does it matter?
The TSSOP48 package has eight GND pins (pins 4, 10, 15, 21, 28, 34, 39, 45) and four VCC pins (7, 18, 31, 42). This distributed power/ground architecture minimizes simultaneous switching noise and ground bounce-critical for maintaining signal integrity in high-speed 16-bit parallel interfaces with fast edge rates.
