Product details
Overview
74LVT16244BDL,112 from NXP Semiconductors is a 16-bit non-inverting buffer/line driver with 3-state outputs, designed for LVTTL bus interface applications. It operates at 3.3 V supply, supports ±64 mA output drive, features 2.8 ns typical propagation delay, and is rated for -40°C to +85°C industrial temperature range. Used in high-speed backplane and motherboard data bus buffering.
For engineers reviewing the 74LVT16244BDL,112 datasheet, 74LVT16244BDL,112 pinout, 74LVT16244BDL,112 application, or 74LVT16244BDL,112 equivalent, key selection criteria include 3.3 V LVTTL compatibility, 16-bit dual-octet channel separation, 3-state enable timing, and SO-48 package thermal performance in dense PCB layouts.
Technical Context
This device implements two independent 8-bit non-inverting buffer sections, each with separate 3-state output enable (OE) controls. Each section supports hot-swap capable I/O with power-up/down high-impedance and bus-hold circuitry on all inputs.
Input thresholds are compatible with both TTL and LVTTL logic families, and output voltage levels meet LVTTL VOH/VOL specifications at 3.3 V. The SO-48 package provides 0.5 mm lead pitch and exposed thermal pad for enhanced thermal dissipation in high-density routing environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.3 V ±0.3 V - ensures compatibility with LVTTL system rails and avoids level-shifting circuitry |
| Propagation Delay | 2.8 ns max (VCC = 3.3 V, CL = 50 pF) - enables reliable operation in 300+ MHz bus systems |
| Output Drive | ±64 mA per output - supports driving 2 LVTTL loads or one 50 Ω transmission line |
| Input Threshold | VIL = 0.8 V, VIH = 2.0 V - guarantees noise margin >0.4 V with 3.3 V LVTTL signaling |
| Operating Temp | -40°C to +85°C - qualified for industrial-grade embedded control and telecom infrastructure |
| ESD Rating | ±2 kV HBM - protects against handling-induced discharge during board assembly |
Pinout & Package
74LVT16244BDL,112 is housed in a 48-pin SO (Small Outline) package with 0.5 mm lead pitch and exposed thermal pad (SO-48EP). The package supports reflow soldering per JEDEC J-STD-020 and provides 4.5°C/W junction-to-case thermal resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A1–1A8 | Section 1 input | Non-inverting input for first octet of buffers; TTL/LVTTL compatible |
| 1Y1–1Y8 | Section 1 output | 3-state buffered output; active-high when OE1 = LOW |
| OE1 | Section 1 output enable | Active-low control; places 1Y1–1Y8 in high-impedance state when HIGH |
| 2A1–2A8 | Section 2 input | Non-inverting input for second octet; electrically isolated from Section 1 |
| 2Y1–2Y8 | Section 2 output | 3-state buffered output; controlled independently by OE2 |
| OE2 | Section 2 output enable | Active-low control; decouples second octet without affecting first |
| VCC | Power supply | 3.3 V supply connection; requires local 100 nF ceramic bypass near pin 24 |
| GND | Ground reference | Common return path; connected to thermal pad for improved heat transfer |
Key Features
| Feature | Design Value |
|---|---|
| Dual 8-bit independent sections | Enables asymmetric bus loading - e.g., one octet drives memory while the other drives peripherals |
| Hot-swap I/O with bus-hold | Maintains valid logic state on unconnected inputs during live insertion, eliminating external pull-ups |
| 3.3 V LVTTL-compatible thresholds | Interoperates directly with FPGA I/O banks and ASICs without level translators |
| SO-48EP thermal pad | Reduces junction temperature rise by up to 15°C vs. standard SO-48 under 500 mW dissipation |
Applications
| High-Speed Backplane Buffering | Industrial PLC I/O Expansion |
|---|---|
Use Scenario: Buffering parallel address/data buses between CPU module and peripheral carrier cards in modular automation chassis. IC Role / Device Role / Timing Role: Non-inverting 3-state bus driver providing signal integrity and load isolation across 200 mm backplane traces. Use Value: 2.8 ns propagation delay ensures setup/hold timing margins remain >1.2 ns at 100 MHz clock rates. | Use Scenario: Interfacing microcontroller GPIOs to relay driver ICs and analog input multiplexers in DIN-rail mounted controllers. IC Role / Device Role / Timing Role: Level-translating buffer isolating 3.3 V MCU logic from 5 V/24 V field-side circuits. Use Value: ±64 mA drive capability allows direct control of optocoupler LEDs without external transistors. |
| Telecom Line Card Interface | Test Equipment Signal Conditioning |
Use Scenario: Driving multiple FPGAs and SerDes PHYs on a single line card with shared control bus architecture. IC Role / Device Role / Timing Role: Dual-section enable control permits staggered activation of FPGA configuration and status monitoring buses. Use Value: Independent OE1/OE2 pins eliminate bus contention during partial reconfiguration sequences. | Use Scenario: Amplifying and conditioning digital stimulus signals from pattern generators before delivery to DUTs in ATE systems. IC Role / Device Role / Timing Role: Low-skew buffer preserving edge fidelity across 16-bit parallel test vectors. Use Value: Matched propagation delays (<0.3 ns skew between Y1–Y8) prevent bit misalignment in high-speed vector capture. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit LVTTL buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC16244ADGGR | 3.3 V only, no 5 V tolerant inputs; 3.5 ns tPD; TSSOP-48 package | Lacks bus-hold; requires external pull resistors on unused inputs | Preferred where board space is constrained and thermal pad not required |
| 74ALVT16244PCB | Higher drive (±64 mA), but 5 V tolerant inputs; 2.5 ns tPD; PLCC-44 package | Compatible with mixed-voltage systems; larger footprint and higher cost | Chosen when interfacing legacy 5 V logic or requiring faster timing margin |
Compared with SN74LVC16244ADGGR and 74ALVT16244PCB, the 74LVT16244BDL,112 uniquely combines bus-hold inputs, SO-48EP thermal performance, and industrial temperature rating - making it optimal for ruggedized, high-density backplane designs where reliability and thermal management are critical.

FAQ
What is the maximum clock frequency supported by 74LVT16244BDL,112?
The device does not operate on a clock signal-it is an asynchronous buffer. Its 2.8 ns typical propagation delay supports reliable operation in systems with data rates up to 350 Mbps on matched-impedance lines, assuming proper PCB layout and termination. Timing margins must be verified per application using worst-case tPLH/tPHL values from the datasheet.
Does 74LVT16244BDL,112 require external pull-up or pull-down resistors on inputs?
No. All inputs feature integrated bus-hold circuitry that maintains the last-valid logic state when left floating, eliminating the need for external biasing resistors. This reduces BOM count and improves reliability in hot-swap or modular backplane environments where connectors may be partially mated.
Can 74LVT16244BDL,112 drive 50 Ω transmission lines directly?
Yes. With ±64 mA output drive capability and 3.3 V supply, the device can source/sink sufficient current to drive a single 50 Ω terminated line (requiring ~66 mA for 3.3 V swing), provided trace impedance is controlled and capacitive load remains ≤50 pF. Layout guidelines recommend series termination near the driver output.
Is the thermal pad on the SO-48EP package electrically connected?
No. The exposed thermal pad on the SO-48EP package is internally connected to GND and must be soldered to a PCB ground plane for optimal thermal performance. Electrical connection to GND via the pad improves heat dissipation and reduces junction temperature by up to 15°C under full-load conditions.
