Product details
Overview
SN74LVT162244AGQLR from Texas Instruments is a 3.3-V ABT 16-bit buffer/driver with 3-state outputs, designed for mixed-mode interfacing between 3.3-V logic and 5-V systems. It provides true outputs, four independent 4-bit channels, symmetrical active-low output-enable inputs, and integrated 22-Ω series output resistors to suppress overshoot/undershoot. It supports hot insertion via Ioff and power-up 3-state functionality.
For engineers reviewing the SN74LVT162244AGQLR datasheet, SN74LVT162244AGQLR pinout, SN74LVT162244AGQLR application, or SN74LVT162244AGQLR equivalent, key selection considerations include its 56-ball VFBGA (GQL) package, 2.7–3.6-V supply range, ±12-mA drive strength per output, support for unregulated battery operation, and distributed VCC/GND layout minimizing high-speed switching noise.
Technical Context
The SN74LVT162244AGQLR implements a flow-through architecture with four independent 4-bit buffer sections, each controlled by dedicated active-low OE inputs (1OE–4OE). Its ABT (Advanced BiCMOS Technology) core enables TTL-compatible input thresholds while operating at 3.3-V VCC, allowing direct connection to both 3.3-V and 5-V signal sources without level shifters.
Each output incorporates an on-die 22-Ω series resistor and supports hot insertion through Ioff circuitry that disables outputs during power-down, preventing backflow current. Power-up 3-state ensures outputs remain high-impedance until VCC exceeds 1.5 V, avoiding bus contention during supply ramp-up.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.7 V to 3.6 V - supports unregulated battery rails and tolerates supply droop without functional loss. |
| Output Drive | ±12 mA per output - sufficient to drive standard TTL loads and moderate PCB trace capacitance without external buffers. |
| Input Voltage | 0 V to 5.5 V - enables direct interface with 5-V CMOS/TTL logic without external level translation. |
| Propagation Delay | Typ. 3.4 ns (tPHL), 3.9 ns (tPLH) at VCC = 3.3 V - suitable for high-speed data bus buffering up to ~100 MHz. |
| Output Resistance | 22 Ω series - reduces signal reflections and EMI by damping edge rates; eliminates need for discrete series termination resistors. |
| Ioff Current | ±100 µA max at VCC = 0 - prevents damaging back-current during hot-plug or partial-power-down scenarios. |
| Thermal Impedance | θJA = 42 °C/W (GQL package) - enables reliable operation in compact, thermally constrained layouts without forced airflow. |
Pinout & Package
The SN74LVT162244AGQLR uses a 56-ball Very Thin Fine-Pitch Ball Grid Array (VFBGA) package designated GQL, measuring 7.1 mm × 6.9 mm × 1.0 mm max height, with 0.65-mm ball pitch and A1 ball located at top-left corner (JRBGA outline ZQL0056A).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE–4OE | Active-low output enable | Independent control per 4-bit group; asserts high-impedance state when high; tied to VCC via pullup if VCC < 1.5 V during power sequencing. |
| 1A1–4A4 | Data inputs | 16 total inputs grouped as four 4-bit buses; accept 0–5.5 V signals regardless of VCC level. |
| 1Y1–4Y4 | True buffered outputs | 16 total outputs with integrated 22-Ω series resistance; source/sink ±12 mA; support hot insertion and mixed-voltage bus driving. |
| VCC / GND | Power and ground | Distributed across package (12 VCC, 12 GND balls) - minimizes simultaneous switching noise and improves PDN impedance. |
| NC | No internal connection | 10 balls marked NC (e.g., A2–A5, K2–K5); must be left unconnected or grounded per PCB design guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Mixed-mode voltage tolerance | 5-V input/output compatibility with 3.3-V VCC - eliminates external level translators in 3.3-V/5-V system interconnects. |
| Integrated output termination | 22-Ω on-die series resistance per output - reduces PCB component count, layout area, and signal integrity risk from unterminated traces. |
| Hot-insertion support | Ioff and power-up 3-state - prevents back-current and bus contention during live board insertion into powered backplanes or carriers. |
| Low-noise power distribution | Distributed VCC and GND pins - lowers simultaneous switching output (SSO) noise and improves signal integrity in high-density routing. |
| Flow-through pinout | Input-to-output alignment across package edges - simplifies layer stacking and reduces trace length/crossing in high-speed bus layouts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit buffer/driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC16244ADGGR | Lower drive (±24 mA), no integrated 22-Ω resistors, 1.65–3.6-V VCC range, TSSOP-48 package. | Lacks built-in termination; requires external series resistors for clean signal integrity on long traces or high-capacitance loads. | Choose when lower cost and wider VCC range outweigh need for integrated termination and hot-insertion support. |
| SN74ALVC16244DGVR | Higher speed (tPD typ. 2.8 ns), ±24-mA drive, no integrated resistors, TVSOP-48, 1.65–3.6-V VCC. | Optimized for minimal propagation delay but lacks Ioff and power-up 3-state - unsuitable for hot-plug environments. | Prefer for fixed-installation, high-frequency data paths where thermal performance and timing margin are prioritized over hot-swap capability. |
Compared with SN74LVC16244ADGGR and SN74ALVC16244DGVR, the SN74LVT162244AGQLR uniquely combines integrated 22-Ω output resistors, guaranteed hot-insertion support, and 5-V tolerant inputs - making it the only option among the three qualified for mixed-voltage backplane interfaces requiring zero-layout overhead and live-service reliability.

FAQ
What is the maximum operating temperature range for the SN74LVT162244AGQLR?
The SN74LVT162244AGQLR is rated for operation from –40°C to +85°C ambient temperature. This commercial-grade specification aligns with its intended use in industrial control systems, telecom equipment, and automotive cabin electronics where environmental stress is moderate but reliability is essential. The GQL package's 42 °C/W thermal resistance supports stable operation within this range under typical PCB copper pour and airflow conditions.
Does the SN74LVT162244AGQLR require external pull-up resistors on its OE pins?
Yes - when VCC is below 1.5 V during power-up or power-down, the SN74LVT162244AGQLR enters high-impedance state automatically. However, to guarantee high-impedance above 1.5 V, each OE pin (1OE–4OE) must be tied to VCC via an external pullup resistor. The minimum value depends on the driver's current-sinking capability; TI recommends verifying against the specific driver's IOL rating in the system context.
Can the SN74LVT162244AGQLR drive 50-pF loads reliably at 100-MHz data rates?
Yes - the SN74LVT162244AGQLR delivers typ. 3.4–3.9 ns propagation delay and <0.5 ns output skew under CL = 50 pF, supporting clean signal edges up to ~100 MHz. Its integrated 22-Ω series resistors further dampen ringing on such loads, and the distributed VCC/GND structure minimizes simultaneous switching noise that could degrade timing margins at high frequencies.
Is the SN74LVT162244AGQLR RoHS-compliant and lead-free?
Yes - the SN74LVT162244AGQLR is manufactured with a green (RoHS & no Sb/Br) eco-plan, featuring SnAgCu (SAC) lead finish and compliant with JEDEC MSL Level-1 moisture sensitivity. It meets all RoHS Directive 2011/65/EU requirements, including ≤0.1% lead by weight in homogeneous materials, and is suitable for lead-free reflow processes up to 260°C peak temperature.
How does the SN74LVT162244AGQLR handle undervoltage conditions during power cycling?
When VCC drops below 1.5 V, the SN74LVT162244AGQLR automatically places all outputs in high-impedance state - preventing bus contention or back-driving. Below 0 V or above 4.6 V, absolute maximum ratings are violated. During ramp-up, power-up 3-state holds outputs inactive until VCC stabilizes, and Ioff circuitry blocks reverse current flow if inputs remain asserted while VCC is absent or near-zero.
