Product details
Overview
SN74LVTH162241 from Texas Instruments is a 3.3-V ABT 16-bit noninverting buffer/driver with 3-state outputs, designed for mixed-mode interfacing between 3.3-V logic and 5-V systems. It features four independent 4-bit sections, bus-hold on all data inputs, integrated 22-Ω output series resistors, and Ioff support for hot insertion. It is used in backplane and motherboard bus interface applications requiring level translation and noise suppression.
For engineers reviewing the SN74LVTH162241 datasheet, SN74LVTH162241 pinout, SN74LVTH162241 application, or SN74LVTH162241 equivalent, key selection criteria include 3.3-V VCC operation with 5-V tolerant inputs, ±12-mA drive strength, 48-pin TSSOP (DGG) package, bus-hold functionality, and power-up 3-state behavior for conflict-free initialization.
Technical Context
This device implements a flow-through pin architecture across four independent 4-bit buffer sections, each with complementary OE/!OE controls enabling simultaneous or staggered 3-state management. Its Advanced BiCMOS Technology (ABT) delivers low static power at 3.3 V while maintaining TTL-compatible thresholds and 5-V input tolerance.
The internal bus-hold circuitry actively maintains valid logic states on floating inputs without external resistors, and the distributed VCC/GND pin layout minimizes high-speed switching noise. Power-up 3-state and Ioff protection ensure safe hot-insertion in live backplanes by disabling outputs during VCC ramp-up or system power-down.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.7 V to 3.6 V - supports unregulated battery operation down to 2.7 V with full functionality. |
| Input Voltage Tolerance | –0.5 V to 5.5 V - enables direct connection to 5-V TTL buses without level shifters. |
| Output Drive Strength | ±12 mA - sufficient to drive standard TTL loads and moderate PCB trace capacitance. |
| Propagation Delay | 1.3 ns (min) to 4.9 ns (max) at VCC = 3.3 V - ensures timing compatibility in high-speed 16-bit bus environments. |
| Bus-Hold Current | ±750 µA max - actively sustains input logic state without external pullup/pulldown resistors. |
| Output Series Resistance | 22 Ω (integrated) - reduces overshoot/undershoot, eliminating need for external termination resistors. |
| Ioff Leakage | ±100 µA max at VCC = 0 - prevents damaging backflow current during hot-swap events. |
Pinout & Package
TSSOP-48 (DGG) package: 12.6 mm × 6.2 mm × 1.2 mm body, 0.5-mm lead pitch, RoHS-compliant NiPdAu finish, MSL Level-1.

| VCC (Pins 7, 15, 23, 31, 39, 47) | Supply | Distributed power pins minimize IR drop and switching noise across the 48-pin array. |
| GND (Pins 4, 12, 20, 28, 36, 44) | Ground | Distributed ground pins provide low-inductance return paths for all output drivers. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 22-Ω output series resistors | Eliminates need for external termination, reducing BOM count and PCB area while suppressing signal ringing. |

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), no integrated 22-Ω resistors, no bus-hold, 3.3-V only I/O (not 5-V tolerant). | Suitable for pure 3.3-V systems where external termination and pullups are acceptable. | Select when cost optimization outweighs mixed-voltage flexibility and board-level simplicity. |
| SN74ALVCH162244DLR | Higher speed (tPD < 3.5 ns), 3.3-V only I/O, no bus-hold, different pinout (SSOP only), no Ioff. | Better for high-frequency 3.3-V-only buses where hot-swap is not required. | Choose for timing-critical designs needing faster propagation but sacrificing 5-V tolerance and hot-insertion safety. |
Compared with SN74LVC16244ADGGR and SN74ALVCH162244DLR, the SN74LVTH162241 uniquely combines 5-V input tolerance, integrated termination, bus-hold, and Ioff-making it the only option among the three qualified for mixed-voltage backplane interfaces requiring zero external components and guaranteed hot-swap robustness.

FAQ
What is the maximum input voltage rating for SN74LVTH162241?
The SN74LVTH162241 supports input voltages up to 5.5 V regardless of VCC level, enabling direct interfacing with 5-V TTL logic while operating from a 3.3-V supply. This 5-V tolerance is specified across the full operating temperature range (–40°C to 85°C) and is validated per absolute maximum ratings in the official datasheet.
Does SN74LVTH162241 require external pullup or pulldown resistors on its inputs?
No, SN74LVTH162241 does not require external pullup or pulldown resistors because it integrates active bus-hold circuitry on all 16 data inputs. This feature maintains valid logic states on floating or unused inputs, eliminating external components and improving reliability in unterminated bus environments.
What package type and dimensions does SN74LVTH162241 use?
SN74LVTH162241 is offered in the TSSOP-48 (DGG) package: 12.6 mm × 6.2 mm body size, 1.2 mm maximum height, and 0.5-mm lead pitch. The package is RoHS-compliant with NiPdAu lead finish and meets JEDEC MO-153 mechanical standards.
Can SN74LVTH162241 be used in hot-swap applications?
Yes, SN74LVTH162241 supports hot insertion via two key features: Ioff circuitry disables outputs when VCC = 0, preventing backflow current, and power-up 3-state ensures outputs remain high-impedance during power ramp-up. These capabilities are fully characterized and documented for industrial backplane applications.
What is the purpose of the complementary OE and !OE inputs on SN74LVTH162241?
SN74LVTH162241 provides separate active-low OE and active-high !OE inputs per 4-bit section to enable flexible control logic design - for example, using one signal to enable multiple sections simultaneously or combining both for gated enable schemes. This dual-control architecture simplifies interface with diverse host controller output configurations.
