Product details
Overview
74LVC162244ADGGRG4 from Texas Instruments is a 16-bit noninverting 3-state buffer/driver with four independent active-low output-enable inputs, operating from 1.65 V to 3.6 V, supporting 5.5-V-tolerant inputs and delivering ≤4.4 ns propagation delay at 3.3 V - used in memory address buffering, bus isolation, and mixed-voltage I/O translation between 3.3-V and 5-V domains.
For engineers reviewing the 74LVC162244ADGGRG4 datasheet, 74LVC162244ADGGRG4 pinout, 74LVC162244ADGGRG4 application, or 74LVC162244ADGGRG4 equivalent, key selection criteria include VCC range compatibility, Ioff-enabled partial-power-down support, 26-Ω on-die series output resistance for signal integrity, and TSSOP-48 package thermal performance (RθJA = 64.3°C/W).
Technical Context
This device implements four independent 4-bit noninverting buffers, each with dedicated active-low OE control (1OE–4OE), enabling selective bus segmentation. All inputs tolerate up to 5.5 V regardless of VCC, allowing safe interfacing with legacy 5-V logic while powered from 1.65–3.6 V supplies.
Each output features integrated 26-Ω series termination to suppress overshoot/undershoot, eliminating external resistors. The Ioff circuit ensures high-impedance outputs and zero current backflow when VCC = 0 V - critical for live insertion and hot-swap applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 3.6 V - enables direct use in modern low-voltage systems including battery-powered and mixed-supply designs. |
| Input Voltage Tolerance | Up to 5.5 V - permits reliable interfacing with 5-V microcontrollers, FPGAs, or legacy peripherals without level shifters. |
| tpd (Max) | 4.4 ns at VCC = 3.3 V - supports high-speed data routing in memory address and clock distribution paths. |
| Ioff Support | Active at VCC = 0 V - prevents damaging back-current during partial power-down or hot-plug events. |
| Output Drive | ±12 mA per output at VCC = 3.0 V - sufficient to drive moderate capacitive loads and multiple CMOS inputs. |
| On-die Series Resistance | 26 Ω per output - reduces signal ringing and EMI without requiring external termination components. |
| ESD Rating | 2000-V HBM, 1000-V CDM - meets industrial-grade robustness requirements for board-level handling and operation. |
Pinout & Package
TSSOP-48 (DGG) package, 12.50 × 6.10 mm body size, 0.5-mm lead pitch, 1.2-mm max height, RoHS-compliant NIPDAU finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE–4OE | Active-low output enable (4×) | Individually disables corresponding 4-bit buffer group; tied high via pullup for power-up high-Z safety. |
| 1A1–4A4 | Buffer input (16×) | 5.5-V-tolerant CMOS inputs accepting 1.65–3.6-V logic levels or 5-V signals directly. |
| 1Y1–4Y4 | Noninverting 3-state output (16×) | Driven high/low when enabled; high-impedance when OE asserted; includes 26-Ω series resistance. |
| VCC (Pins 7, 18, 31, 42) | Power supply (4×) | Distributed supply pins reduce IR drop and improve noise immunity across wide bus layouts. |
| GND (Pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground return (8×) | Multiple GND pins minimize ground bounce and support clean signal integrity for all 16 outputs. |
Key Features
| Feature | Design Value |
|---|---|
| Mixed-voltage translation | 5.5-V-tolerant inputs operate reliably with 3.3-V or 5-V drivers - eliminates discrete level shifters in heterogeneous systems. |
| Ioff partial-power-down | Outputs enter high-Z state with zero back-current when VCC = 0 V - essential for hot-swap and modular backplane designs. |
| Integrated 26-Ω output series resistance | Reduces edge-induced overshoot/undershoot and EMI without external components - simplifies PCB layout and BOM. |
| Low propagation delay | 4.4 ns max at 3.3 V enables timing-critical applications such as memory address latching and clock fanout. |
| Wide temperature range | –40°C to +125°C operation supports industrial, automotive under-hood, and telecom infrastructure deployments. |

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 |
|---|---|---|---|
| SN74LVC162244ADGGR | No G4 suffix; identical electrical specs and pinout; same TSSOP-48 package and RoHS/NIPDAU finish. | No functional difference; G4 denotes TI's green packaging standard (halogen-free, Pb-free). | Select 74LVC162244ADGGRG4 for full compliance with latest environmental directives; otherwise, DGGR is functionally interchangeable. |
| 74ALVC162244DGGR | Wider VCC range (1.65–3.6 V same), but higher drive (±24 mA), faster tpd (≤3.2 ns), and no 5.5-V input tolerance. | Better for speed-critical, single-supply 3.3-V systems; unsuitable for 5-V input interfacing or mixed-voltage translation. | Choose 74ALVC162244DGGR only if 5-V tolerance is unnecessary and sub-3.5 ns delay is required; otherwise, LVC version offers broader system compatibility. |
Compared with SN74LVC162244ADGGR and 74ALVC162244DGGR, the 74LVC162244ADGGRG4 uniquely balances 5.5-V input tolerance, Ioff safety, and industrial temperature range - making it optimal for mixed-voltage, hot-swap, and long-lifecycle embedded systems where reliability and interoperability outweigh marginal speed gains.

FAQ
What is the maximum input voltage rating for 74LVC162244ADGGRG4?
The 74LVC162244ADGGRG4 accepts input voltages up to 5.5 V across its entire valid VCC range (1.65–3.6 V). This overvoltage tolerance enables direct connection to 5-V logic sources without external level-shifting circuitry, supporting seamless integration in mixed-voltage systems where 3.3-V and 5-V devices coexist on the same board.
Does 74LVC162244ADGGRG4 support partial power-down operation?
Yes, the 74LVC162244ADGGRG4 incorporates Ioff circuitry that actively disables outputs and blocks current flow when VCC = 0 V. This feature protects against damaging back-current during hot-swap, live insertion, or partial system power-down - a critical capability for modular industrial and telecom equipment where subsystems may be powered independently.
What is the purpose of the 26-Ω series resistance on each output of 74LVC162244ADGGRG4?
The 26-Ω on-die series resistance in the 74LVC162244ADGGRG4 dampens fast signal edges, reducing overshoot, undershoot, and ringing on transmission lines. This built-in termination eliminates the need for external resistors, simplifying PCB layout, lowering BOM cost, and improving signal integrity - especially beneficial when driving moderate capacitive loads or unterminated stubs in memory or test interfaces.
How many independent output-enable controls does 74LVC162244ADGGRG4 provide?
The 74LVC162244ADGGRG4 provides four independent active-low output-enable inputs: 1OE, 2OE, 3OE, and 4OE. Each controls a dedicated 4-bit buffer section (1A1–1A4/1Y1–1Y4, etc.), enabling granular bus segmentation, selective signal routing, and fault-isolated operation - ideal for applications like multi-channel test fixtures or modular backplane architectures.
What package type and thermal performance does 74LVC162244ADGGRG4 use?
The 74LVC162244ADGGRG4 uses a TSSOP-48 (DGG) package measuring 12.50 × 6.10 mm with 0.5-mm pitch. Its junction-to-ambient thermal resistance (RθJA) is 64.3°C/W, supporting reliable operation at full load across –40°C to +125°C ambient temperatures - validated for industrial and automotive under-hood environments where thermal management is critical.
