Product details
Overview
74LVT162244ADGGRE4 from Texas Instruments is a 3.3-V ABT 16-bit noninverting buffer/driver with 3-state outputs, designed for mixed-mode signal operation (5-V inputs/outputs with 3.3-V VCC), featuring 22-Ω integrated series output resistors, ±12 mA drive capability per output, and hot-insertion support via Ioff and power-up 3-state logic. It serves as a level-shifting bus interface in high-speed digital systems such as telecom backplanes and industrial control modules.
For engineers reviewing the 74LVT162244ADGGRE4 datasheet, 74LVT162244ADGGRE4 pinout, 74LVT162244ADGGRE4 application, or 74LVT162244ADGGRE4 equivalent, key selection considerations include its TSSOP-48 package, 2.7–3.6 V supply range, 3.3-V ABT logic family compatibility, 4.6 ns typical propagation delay (tPLH), and 0.8 V typical VOL at 12 mA sink current.
Technical Context
The 74LVT162244ADGGRE4 implements four independent 4-bit noninverting buffers, each with an active-low 3-state output-enable (OE) input. Its ABT (Advanced BiCMOS Technology) architecture integrates 22-Ω series resistors on all outputs to suppress overshoot/undershoot without external components.
It supports hot insertion via Ioff (input/output off-state current ≤ ±100 µA at VCC = 0) and power-up 3-state behavior, ensuring outputs remain high-impedance during power ramping (VCC = 0–1.5 V). Distributed VCC/GND pins and flow-through pinout minimize switching noise and optimize PCB layout routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.7 V to 3.6 V - enables stable operation under unregulated battery supply down to 2.7 V. |
| IOH/IOL | –12 mA / +12 mA - sufficient to drive standard TTL loads and 50-pF transmission lines directly. |
| tPLH/tPHL | 4.6 ns / 4.5 ns (typ, VCC = 3.3 V) - supports >100 MHz bus timing in synchronous systems. |
| VOL/VOLP | 0.8 V (max, IOL = 12 mA) / <0.8 V (VOLP, ground bounce) - ensures clean low-level signaling in noisy environments. |
| VIH/VIL | 2.0 V / 0.8 V - compatible with 5-V TTL input thresholds while operating at 3.3-V VCC. |
| Input/Output Clamp | ±50 mA clamp current - protects against transient overvoltage events per JESD 22 standards. |
| ESD Rating | 2000-V HBM, 200-V MM, 1000-V CDM - meets industrial-grade robustness requirements. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE, 3OE, 4OE | Active-low output enable | Controls 4-bit group (1Y–4Y); OE = low enables outputs, OE = high places them in high-Z state. |

| 1Y1–1Y4, 2Y1–2Y4, 3Y1–3Y4, 4Y1–4Y4 | True buffered outputs | Source/sink up to 12 mA with built-in 22-Ω series termination; no external resistors needed. |
| VCC (Pins 7, 18, 31, 42) | Power supply | Distributed VCC pins reduce simultaneous switching noise and improve power integrity across 16-bit bus. |
| GND (Pins 4, 10, 15, 21, 27, 32, 37, 45) | Ground reference | Eight GND pins provide low-inductance return paths and minimize ground bounce (VOLP < 0.8 V). |

FAQ
What is the recommended operating voltage range for the 74LVT162244ADGGRE4?
The 74LVT162244ADGGRE4 operates reliably from 2.7 V to 3.6 V. This range supports unregulated battery-powered systems and ensures compatibility with standard 3.3-V power rails. Operation below 2.7 V may cause undefined output states, while exceeding 3.6 V risks violating absolute maximum ratings. The device maintains full 5-V input tolerance across this entire VCC window, enabling robust mixed-voltage interfacing in the 74LVT162244ADGGRE4.
Does the 74LVT162244ADGGRE4 support hot insertion, and how is it implemented?
Yes, the 74LVT162244ADGGRE4 supports hot insertion via two complementary features: Ioff circuitry disables outputs when VCC = 0, limiting backflow current to ±100 µA, and power-up 3-state logic forces outputs into high-impedance during VCC ramp (0–1.5 V). These mechanisms prevent bus contention and damage during live board replacement - a core requirement validated in the 74LVT162244ADGGRE4 datasheet and essential for telecom and industrial chassis applications.
What is the function of the 22-Ω series resistors integrated into the 74LVT162244ADGGRE4 outputs?
The 22-Ω series resistors integrated into each output of the 74LVT162244ADGGRE4 dampen signal reflections and suppress overshoot/undershoot on transmission lines, eliminating the need for external termination resistors. This reduces PCB component count, saves layout space, and improves signal fidelity in high-speed parallel buses - a verified design feature confirmed in the 74LVT162244ADGGRE4 functional description and electrical characteristics tables.
How many independent 3-state control inputs does the 74LVT162244ADGGRE4 have, and what do they control?
The 74LVT162244ADGGRE4 has four independent active-low 3-state enable inputs: 1OE, 2OE, 3OE, and 4OE. Each controls one 4-bit buffer group (e.g., 1OE enables/disables outputs 1Y1–1Y4). This granular control allows partial bus isolation - for example, disabling only sensor channel 3 while keeping communication channels 1–2 active - a capability explicitly defined in the 74LVT162244ADGGRE4 function table and logic diagram.
Is the 74LVT162244ADGGRE4 pin-compatible with other packages in the LVT162244A family?
Yes, the 74LVT162244ADGGRE4 (TSSOP-48) shares identical pinout and functionality with SN74LVT162244ADGVR (TVSOP-48) and SN74LVT162244ADLR (SSOP-48), as confirmed by TI's terminal assignment diagrams and ordering information. All three use the same 48-pin mapping, including VCC/GND distribution and OE/A/Y signal locations. This allows drop-in substitution across packages based on thermal, density, or assembly requirements - a verified mechanical and logical equivalence documented for the 74LVT162244ADGGRE4.
