Product details
Overview
SN74LVC162244ADGGR from Texas Instruments is a 16-bit noninverting 3-state buffer/driver with four independent 4-bit sections, operating from 1.65 V to 3.6 V, supporting 5.5-V-tolerant inputs and delivering ±12 mA output drive at 3.3 V - used in memory address buffering, bus isolation, and mixed-voltage I/O translation in industrial control backplanes.
For engineers reviewing the SN74LVC162244ADGGR datasheet, SN74LVC162244ADGGR pinout, SN74LVC162244ADGGR application, or SN74LVC162244ADGGR equivalent, key selection criteria include 3-state enable timing (tdis ≤ 6.3 ns), Ioff-enabled live insertion support, 26-Ω on-die series termination, and TSSOP-48 package compatibility with 0.5-mm pitch PCB layouts.
Technical Context
This device implements four independent 4-bit noninverting buffers, each with dedicated active-low output-enable (OE) control - enabling selective bus section isolation without affecting other channels. Each buffer supports true (noninverting) signal transmission and features symmetrical input thresholds defined across VCC = 1.65–3.6 V.
Its Ioff circuitry ensures high-impedance outputs when VCC = 0 V, blocking current backflow during partial power-down; inputs tolerate up to 5.5 V regardless of VCC level, permitting reliable interfacing between 3.3-V logic and legacy 5-V peripherals or sensors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 3.6 V - enables direct integration into modern low-voltage systems while maintaining backward compatibility with 2.5-V and 3.3-V rails. |
| Input Voltage Tolerance | Up to 5.5 V - allows safe connection to 5-V sources without external level-shifting components. |
| Max Output Drive | ±12 mA at VCC = 3 V - sufficient to drive moderate capacitive loads (e.g., 30-pF traces + multiple CMOS inputs) without external buffers. |
| Propagation Delay | 1.1 ns to 4.4 ns at VCC = 3.3 V - supports high-speed data routing in memory and peripheral buses up to ~200 MHz. |
| Ioff Support | Active at VCC = 0 V - prevents damaging back-current during hot-swap or staged power sequencing in modular systems. |
| ESD Rating | 2000-V HBM, 1000-V CDM - meets industrial-grade robustness requirements for board-level handling and field operation. |
| On-Die Termination | 26 Ω series output resistance - reduces overshoot/undershoot and eliminates need for discrete series resistors in point-to-point routing. |
Pinout & Package
TSSOP-48 (DGG) package: 12.50 × 6.10 mm body, 0.5-mm lead pitch, 1.2-mm max height, RoHS-compliant NiPdAu finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE, 3OE, 4OE | Active-low output enable | Individually disables corresponding 4-bit buffer section; tied high via pullup for default enabled state during power-up. |
| 1A1–1A4, 2A1–2A4, 3A1–3A4, 4A1–4A4 | Buffer input | 16 total CMOS-compatible inputs; accept 0–5.5 V regardless of VCC, enabling mixed-voltage domain bridging. |
| 1Y1–1Y4, 2Y1–2Y4, 3Y1–3Y4, 4Y1–4Y4 | Buffer output | 16 true (noninverting) 3-state outputs; each includes 26-Ω series resistance to dampen edge-induced ringing. |
| VCC (Pins 7, 18, 31, 42) | Power supply | Four dedicated VCC pins distributed across package - reduce IR drop and improve noise immunity in high-current switching scenarios. |
| GND (Pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight GND pins provide low-inductance return paths, critical for maintaining signal integrity and minimizing ground bounce (VOLP < 0.8 V). |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range | 1.65–3.6 V operation supports single-rail deployment across 1.8-V, 2.5-V, and 3.3-V system domains. |
| 5.5-V tolerant inputs | Enables direct interface to 5-V microcontrollers, sensors, or legacy peripherals without external translators. |
| 26-Ω integrated series termination | Eliminates need for discrete 22–33-Ω resistors per line, reducing BOM count and PCB area in dense bus designs. |
| Ioff partial-power-down protection | Prevents destructive current flow when SN74LVC162244ADGGR is unpowered but connected to live buses. |
| Low ground bounce (VOLP) | <0.8 V at VCC = 3.3 V - maintains noise margin in multi-driver environments like memory address latching. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer/driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC162244ADGVR | Identical electrical specs; uses TVSOP-48 (DGV) package - 9.70 × 4.40 mm, 0.4-mm pitch, 1.2-mm height. | Better suited for ultra-dense PCBs where footprint area is constrained; slightly higher thermal resistance (RθJA = 78.4°C/W vs. 64.3°C/W). | Select SN74LVC162244ADGVR when board space is premium and thermal load is moderate; verify solder paste volume for finer pitch. |
| SN74ALVC162244DGGR | Higher speed: tpd ≤ 3.2 ns at 3.3 V; wider VCC range (1.65–3.6 V same); identical pinout and Ioff support. | Preferred for timing-critical applications like DDR address/command routing where sub-4-ns delay is mandatory. | Choose SN74ALVC162244DGGR only if SN74LVC162244ADGGR's 4.4-ns tpd violates timing budget - otherwise, LVC version offers better cost/performance balance. |
Compared with SN74LVC162244ADGVR, the SN74LVC162244ADGGR offers lower thermal resistance and broader design margin for thermally demanding industrial enclosures; versus SN74ALVC162244DGGR, it trades 1.2 ns of propagation delay for reduced dynamic power and proven long-term reliability in temperature-cycled deployments.

FAQ
What is the maximum input voltage the SN74LVC162244ADGGR can safely accept?
The SN74LVC162244ADGGR accepts input voltages up to 5.5 V across its entire valid VCC range (1.65–3.6 V), enabling direct interfacing with 5-V logic without external level shifters. This overvoltage tolerance is guaranteed per TI's absolute maximum ratings and applies to all 16 input pins (1A1–4A4), making SN74LVC162244ADGGR ideal for mixed-voltage system integration.
Does the SN74LVC162244ADGGR support hot-swap or live-insertion applications?
Yes, the SN74LVC162244ADGGR supports live insertion via its Ioff feature: when VCC = 0 V, all outputs enter high-impedance state and input/output leakage remains below ±10 µA, preventing damaging back-current flow. This capability is validated per JESD78 Class II latch-up testing and is critical for modular PLC backplanes or field-replaceable compute cards using SN74LVC162244ADGGR for bus isolation.
What is the purpose of the four separate output-enable (OE) pins on the SN74LVC162244ADGGR?
The four active-low OE pins (1OE–4OE) independently control the 3-state output drivers for each 4-bit buffer section (1Y1–1Y4, etc.), allowing selective bus segmentation. This enables dynamic isolation of memory banks, peripheral clusters, or test signal groups without disabling the entire 16-bit path - a key requirement in fault-tolerant industrial controllers using SN74LVC162244ADGGR for partitioned resource management.
How does the integrated 26-Ω series output resistance benefit PCB layout for the SN74LVC162244ADGGR?
The SN74LVC162244ADGGR's on-die 26-Ω series termination damps signal edge reflections on unterminated traces, reducing overshoot (<2 V VOHV) and undershoot (<0.8 V VOLP) without requiring discrete resistors. This simplifies layout for high-speed parallel buses - especially beneficial in compact TSSOP-48 designs where routing density limits space for external components near SN74LVC162244ADGGR output pins.
What thermal considerations apply to the SN74LVC162244ADGGR in continuous 16-bit switching operation?
In worst-case operation (all 16 outputs driving ±12 mA at 3.3 V), SN74LVC162244ADGGR dissipates ~0.63 W. With its TSSOP-48 RθJA of 64.3°C/W, junction temperature rise is ~40°C above ambient - well within the –40°C to 125°C operating range. For sustained high-load use, ensure ≥2 cm² of 2-oz copper pour under the SN74LVC162244ADGGR footprint and maintain airflow >0.5 m/s in sealed enclosures.
