Product details
Overview
SN74LVTH162241DLR 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 four independent 4-bit sections, bus-hold on all data inputs, integrated 22-Ω output series resistors, and Ioff support for hot insertion. It operates from –40°C to 85°C and is used in backplane drivers, memory address buffering, and bus isolation in industrial control systems.
For engineers reviewing the SN74LVTH162241DLR datasheet, SN74LVTH162241DLR pinout, SN74LVTH162241DLR application, or SN74LVTH162241DLR equivalent, key selection criteria include 3.3-V VCC compatibility with 5-V tolerant inputs, guaranteed 12-mA drive strength per output, bus-hold functionality eliminating external biasing, and SSOP-48 packaging suitable for high-density PCB layouts.
Technical Context
This device implements an Advanced BiCMOS Technology (ABT) architecture optimized for low static power at 3.3-V operation while maintaining TTL-compatible input thresholds and 5-V signal tolerance. Each of its four 4-bit sections has complementary OE/!OE controls enabling independent 3-state management.
The flow-through pinout minimizes trace skew and simplifies routing, while distributed VCC/GND pins reduce simultaneous switching noise. Bus-hold circuitry maintains valid logic levels on floating inputs without external resistors, and Ioff protection prevents current backflow during partial power-down-critical for hot-swap applications.
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. |
| IOH/IOL | ±12 mA - drives standard TTL loads directly without external pull-ups or series termination. |
| VIH/VIL | 2.0 V / 0.8 V - compatible with both 3.3-V CMOS and 5-V TTL input logic levels. |
| tPLH/tPHL | 1.3 ns to 4.9 ns @ 3.3 V - enables high-speed bus buffering up to ~200 MHz effective data rates. |
| Bus-Hold Current | ±750 µA max - actively holds unused inputs at valid logic states, eliminating external bias components. |
| Ioff | ±100 µA @ VCC = 0 - blocks current flow between powered and unpowered sections during hot insertion. |
| Output Series R | 22 Ω internal - reduces overshoot/undershoot, enabling clean signal edges without discrete damping resistors. |
Pinout & Package
SN74LVTH162241DLR is housed in a 48-pin Shrink Small-Outline Package (SSOP-DL), 12.6 mm × 6.2 mm × 1.95 mm body, with 0.5-mm pitch, RoHS-compliant NiPdAu lead finish, and MSL Level-1 rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A1–4A4 (Pins 1,47,46,44,43,48,41,40,38,37,25,36,35,33,32,24,30,29,27,26) | Data Inputs | 20 total inputs grouped into four 4-bit banks; each bank has dedicated OE control. |

| 1OE, 2OE, 3OE, 4OE (Pins 42, 45, 34, 31) | Active-Low Output Enables | Four independent active-low enables; each controls one 4-bit output group. |
| VCC (Pins 7, 21, 39, 48) | Power Supply | Distributed VCC pins minimize IR drop and supply noise across high-speed switching banks. |
| GND (Pins 4, 10, 15, 18, 28, 33) | Ground Reference | Multiple GND pins adjacent to VCC and I/O clusters suppress ground bounce and crosstalk. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 22-Ω output series resistors | Eliminates need for external termination, reducing BOM count and PCB area while controlling edge rates. |
| Bus-hold on all data inputs | Maintains stable logic state on unterminated or floating inputs-no external pull-up/pull-down resistors required. |
| Ioff and power-up 3-state | Enables safe hot insertion by disabling outputs when VCC = 0 and holding high-impedance during power ramp. |
| Mixed-mode signal operation | Accepts 5-V inputs with 3.3-V VCC and drives 5-V-tolerant loads-ideal for bridging legacy and low-voltage subsystems. |
| Flow-through architecture | Input-to-output pin mapping minimizes trace length and layer transitions, improving signal integrity and layout efficiency. |
Applications

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 bus-hold, no internal series resistors, 1.65–3.6 V VCC range. | Lacks hot-insertion support and 5-V input tolerance; requires external termination and biasing. | Choose for cost-sensitive, fully 3.3-V-only systems where board space allows external components. |
| SN74ALVCH162244DLR | Higher speed (tPLH ≤ 3.2 ns), same 2.3–3.6 V VCC, includes bus-hold but no internal 22-Ω resistors. | Requires external series resistors for EMI control; not rated for 5-V input operation. | Select when maximum propagation speed is critical and 5-V interface is unnecessary. |
Compared with SN74LVC16244ADGGR and SN74ALVCH162244DLR, SN74LVTH162241DLR uniquely combines 5-V input tolerance, integrated 22-Ω termination, bus-hold, and Ioff-making it the only option among the three qualified for mixed-voltage hot-swap backplane designs without additional discrete components.

FAQ
What is the operating temperature range for SN74LVTH162241DLR?
The SN74LVTH162241DLR is characterized for operation from –40°C to +85°C ambient temperature. This industrial-grade range ensures reliable performance in factory automation, outdoor telecom enclosures, and motor control cabinets where thermal cycling occurs. The device's ABT process technology maintains consistent timing and drive strength across this full span without derating.
Does SN74LVTH162241DLR support 5-V input signals while powered at 3.3 V?
Yes, SN74LVTH162241DLR supports 5-V input signals with VCC = 3.3 V. Its input structure tolerates VI up to 5.5 V, enabling direct connection to legacy 5-V TTL outputs without level shifters. This mixed-mode capability is confirmed in the Recommended Operating Conditions table and is a core design feature of the ABT logic family.
How does the bus-hold feature work on SN74LVTH162241DLR?
The bus-hold circuitry on SN74LVTH162241DLR applies weak feedback to maintain the last-valid logic state on any floating input. With a typical hold current of ±750 µA, it prevents metastability and noise-induced toggling-eliminating the need for external pull-up or pull-down resistors. This function is active whenever VCC is within specification and requires no configuration.
Can SN74LVTH162241DLR be used in hot-swap applications?
Yes, SN74LVTH162241DLR is explicitly designed for hot-insertion. Its Ioff protection disables outputs when VCC = 0, preventing damaging current backflow, and its power-up 3-state circuitry forces outputs into high-impedance during power ramp. These features are validated per JEDEC JESD78 and documented in the datasheet's "Hot-Insertion Applications" section.
What package type is SN74LVTH162241DLR supplied in?
SN74LVTH162241DLR is supplied in a 48-pin Shrink Small-Outline Package (SSOP-DL), measuring 12.6 mm × 6.2 mm × 1.95 mm with 0.5-mm lead pitch.
