Product details
Overview
74ALVT162244DGG,11 from NXP Semiconductors (formerly Philips) is a 2.5V/3.3V 16-bit non-inverting 3-State buffer/driver with integrated 30Ω series output termination resistors, designed for high-speed bus interface applications including memory address drivers and clock distribution. It features ±12mA drive strength, 5V-tolerant I/O, and bus-hold inputs eliminating external pull-ups.
For engineers reviewing the 74ALVT162244DGG,11 datasheet, 74ALVT162244DGG,11 pinout, 74ALVT162244DGG,11 application, or 74ALVT162244DGG,11 equivalent, this page delivers verified electrical parameters, TSSOP-48 package details, functional pin mapping, real-world use cases in backplane and memory subsystems, and two validated alternative parts with precise technical distinctions.
Technical Context
The 74ALVT162244DGG,11 implements four independent 4-bit non-inverting buffers, each with dedicated 3-State enable (OE) control. Its BiCMOS architecture enables operation at either 2.5V (±0.2V) or 3.3V (±0.3V) while maintaining full 5V I/O tolerance on all inputs and outputs.
Each output integrates matched 30Ω series resistance in both high and low states-verified in schematic diagrams and AC test conditions-to suppress transmission-line reflections without requiring external termination. Bus-hold circuitry on all data inputs maintains valid logic states on unused pins without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.3–2.7V or 3.0–3.6V - Dual-voltage support enables interoperability across 2.5V and 3.3V system domains. |
| Output Drive | ±12mA - Sustains robust signal integrity driving 50pF loads at ≤2.2ns propagation delay (3.3V). |
| Input Voltage Range | 0–5.5V - Full 5V tolerance allows direct interfacing to legacy TTL and CMOS buses without level shifters. |
| Integrated Termination | 30Ω series resistor per output - Eliminates need for discrete termination resistors on PCB traces. |
| Bus-Hold Current | ±75µA to ±130µA - Actively retains input state during floating conditions, removing external pull-up/down requirements. |
| 3-State Enable Time | 1.5–3.2ns (tPZH/tPZL) - Fast output activation supports high-frequency bus arbitration and multiplexing. |
| Quiescent Supply Current | 40µA (2.5V) / 70µA (3.3V) - Ultra-low ICCZ enables power-sensitive applications when outputs are disabled. |
Pinout & Package
74ALVT162244DGG,11 is housed in a 48-pin plastic Thin Shrink Small Outline Package (TSSOP), body width 6.1 mm (SOT362-1), lead pitch 0.5 mm, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 48 | 1OE, 2OE | Active-low enable for first and second 4-bit buffer groups - controls Y0–Y3 outputs of channels 1 and 2. |

GND | Ground reference - eight dedicated GND pins minimize ground bounce in high-speed switching. |
| 7, 18, 31, 42 | VCC | Positive supply - four VCC pins ensure stable power delivery across wide operating temperature range (–40°C to +85°C). |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 30Ω Output Termination | Reduces PCB component count and layout complexity by embedding series resistance directly in output path - eliminates discrete termination resistors for point-to-point or stub-loaded buses. |
| 5V-Tolerant I/O | Enables seamless integration into mixed-voltage systems where 2.5V/3.3V logic drives or receives signals from 5V peripherals without external translators. |
| Bus-Hold Inputs | Maintains last-valid logic state on unconnected or unterminated inputs using internal feedback - prevents floating nodes and system-level glitches. |
| Live Insertion/Extraction Support | Power-up 3-State and latch-up immunity (>500mA) allow hot-plug operation in modular backplanes and field-replaceable units without damaging adjacent circuitry. |
| Low-Noise Propagation | Typical tPLH/tPHL = 2.2ns (3.3V) with controlled edge rates (10 ns/V) minimizes crosstalk and EMI in dense routing environments. |

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 |
|---|---|---|---|
| SN74ALVTH162244DGGR | TI part uses ALVT process but lacks integrated 30Ω termination; requires external resistors for clean signaling. | Not suitable for space-constrained designs where termination resistor placement is impractical. | Select only if existing layout already includes termination resistors and voltage compatibility (2.3–3.6V) matches. |
| 74LVT162244MTDX | ON Semiconductor version omits bus-hold inputs - requires external pull-ups on unused A-pins. | Increases risk of floating-input-induced glitches in partially populated systems or during firmware initialization. | Prefer only when bus-hold functionality is unnecessary and board-level pull-ups are already implemented. |
Compared with SN74ALVTH162244DGGR and 74LVT162244MTDX, the 74ALVT162244DGG,11 uniquely combines integrated 30Ω termination, bus-hold inputs, and live-insertion capability - delivering lowest component count and highest system-level noise immunity in compact 3.3V/2.5V bus interfaces.

FAQ
What voltage levels does the 74ALVT162244DGG,11 support for VCC and I/O operation?
The 74ALVT162244DGG,11 operates with VCC at either 2.5V (±0.2V) or 3.3V (±0.3V), while all inputs and outputs tolerate 0–5.5V - enabling direct connection to 5V buses without level-shifting circuitry. This dual-voltage capability is confirmed in the Recommended Operating Conditions table on page 4 of the Philips specification.
Does the 74ALVT162244DGG,11 include built-in termination resistors, and what is their value?
Yes, the 74ALVT162244DGG,11 integrates 30Ω series resistors in both high and low output states - explicitly stated in the product title, Features list, and schematically illustrated on page 3. These resistors dampen transmission-line reflections, eliminating the need for external termination components on PCB traces.
How many independent 3-State enable controls does the 74ALVT162244DGG,11 provide?
The 74ALVT162244DGG,11 provides four independent active-low 3-State enable inputs: 1OE (pin 1), 2OE (pin 48), 3OE (pin 25), and 4OE (pin 24). Each controls a separate 4-bit buffer group (A0–A3 → Y0–Y3), allowing granular bus segmentation and power-aware gating.
Is bus-hold functionality present on all input pins of the 74ALVT162244DGG,11, and how does it function?
Yes, all 16 data inputs (A0–A3 across four groups) feature bus-hold circuitry, as confirmed in the Features section and DC Electrical Characteristics tables. It applies ±75µA to ±130µA overdrive current to retain the last-valid logic state when inputs float - removing dependency on external pull-up or pull-down resistors.
What is the maximum propagation delay for the 74ALVT162244DGG,11 under 3.3V operation?
Under 3.3V operation with CL = 50pF, the maximum propagation delay (tPLH/tPHL) is 3.3ns, as specified in the AC Characteristics table on page 5. Typical delay is 2.2ns, supporting reliable operation in systems with ≥300 MHz clock domains when used for address or control buffering.
