Product details
Overview
SN74LVTH16244AGQLR from Texas Instruments is a 3.3-V ABT 16-bit noninverting buffer/driver with 3-state outputs, designed for mixed-mode TTL/3.3-V system interfacing. It features bus-hold circuitry on all inputs, Ioff support for hot insertion, and operates across 2.7 V to 3.6 V supply range. It delivers ±64 mA output drive at VCC = 3.3 V and supports 5-V-tolerant inputs in 3.3-V systems - used in backplane interface, memory expansion, and FPGA I/O bridging.
For engineers reviewing the SN74LVTH16244AGQLR datasheet, SN74LVTH16244AGQLR pinout, SN74LVTH16244AGQLR application, or SN74LVTH16244AGQLR equivalent, key selection criteria include its 56-ball VFBGA (GQL) package, true 3-state control with active-low OE per 4-bit group, bus-hold functionality eliminating external resistors, and verified 2.7–3.6 V operation with 5-V input compatibility.
Technical Context
The SN74LVTH16244AGQLR implements Advanced BiCMOS Technology (ABT) for low static power and high-speed performance at 3.3 V. Its architecture includes four independent 4-bit buffer sections, each with dedicated active-low output-enable (OE) inputs (1OE–4OE), symmetrical output drive, and integrated bus-hold on all 16 data inputs.
It supports hot insertion via Ioff and power-up 3-state logic, ensuring outputs remain high-impedance during power ramping (VCC < 1.5 V) and preventing backflow current. The device meets JESD 17 latch-up immunity (>500 mA) and exceeds JESD 22 ESD ratings (2000-V HBM, 200-V MM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.7 V to 3.6 V - enables stable operation under unregulated battery or noisy rail conditions. |
| IOL / IOH | 64 mA / –32 mA at VCC = 3.3 V - drives heavy capacitive loads or multiple TTL inputs without external buffers. |
| tPLH / tPHL | 2.3 ns / 2.0 ns typical at VCC = 3.3 V, CL = 50 pF - supports >200 MHz data rates in point-to-point or stub-bus topologies. |
| VIH / VIL | 2.0 V / 0.8 V - ensures reliable TTL-level recognition while operating from 3.3-V supply. |
| Bus-Hold Current | ±75 µA at VI = 2 V or 0.8 V - actively holds floating inputs at valid logic states, removing need for pullup/pulldown resistors. |
| IOFF Leakage | ±100 µA at VCC = 0 V - blocks damaging back-current during hot-swap or partial-power-down scenarios. |
| θJA | 42 °C/W (GQL package) - enables thermal management in dense BGA layouts without forced airflow. |
Pinout & Package
SN74LVTH16244AGQLR uses a 56-ball Very Thin Fine-Pitch Ball Grid Array (VFBGA) package designated GQL (MicroStar Junior), measuring 7.0 mm × 4.5 mm × 0.9 mm, RoHS-compliant with SnPb ball finish and MSL Level-1 rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE–4OE | Active-low output-enable control | Independent enable per 4-bit section; asserts high-impedance state when high - enables selective bus gating. |
| 1A1–4A4 | Data inputs | All 16 inputs feature bus-hold; no external biasing required - simplifies PCB layout and improves noise immunity. |
| 1Y1–4Y4 | True buffered outputs | Noninverting, 3-state outputs with symmetrical drive strength - supports bidirectional data flow when paired with complementary devices. |
| VCC / GND | Power terminals | Four VCC and six GND balls distributed across array - reduces simultaneous switching noise and improves PDN integrity. |
| NC | No internal connection | Ball positions A2–A5, K2–K4, K6 are unconnected - must be left unpopulated or grounded per PCB design rules. |
Key Features
| Feature | Design Value |
|---|---|
| Mixed-mode signal operation | 5-V-tolerant inputs with 3.3-V VCC - interfaces legacy TTL logic without level shifters in hybrid voltage systems. |
| Hot-insertion support | Ioff + power-up 3-state - prevents bus contention and backdrive damage during live board replacement in telecom or server backplanes. |
| Integrated bus-hold | Eliminates 32 external pullup/pulldown resistors for 16 inputs - reduces BOM count, board area, and routing complexity. |
| Low ground bounce | VOLP < 0.8 V at VCC = 3.3 V - maintains signal integrity during fast switching in high-density digital systems. |
| Wide operating temperature | –40°C to 85°C - qualified for industrial and commercial environments including base station control cards and test equipment. |
