Product details
Overview
74ALVT162240DGG,11 from NXP Semiconductors (formerly Philips) is a 16-bit inverting 3-State buffer/driver with integrated 30Ω series output termination, designed for 2.5V/3.3V VCC operation and 5V-tolerant I/O. It delivers ±12mA drive strength, features four independent Output Enable inputs (1OE–4OE), and incorporates bus-hold on all data inputs to eliminate external pull-ups. It is used in high-speed memory address and clock distribution buses where signal integrity and reduced external component count are critical.
For engineers reviewing the 74ALVT162240DGG,11 datasheet, 74ALVT162240DGG,11 pinout, 74ALVT162240DGG,11 application, or 74ALVT162240DGG,11 equivalent, this page provides verified functional identity, confirmed 48-pin TSSOP package mapping, validated 30Ω series-terminated output architecture, bus-hold input behavior, and real-world timing and drive specifications per 3.3V and 2.5V operating ranges.
Technical Context
The 74ALVT162240DGG,11 implements a BiCMOS architecture enabling dual-supply compatibility: VCC at 2.5V ±0.2V or 3.3V ±0.3V while accepting TTL-level inputs up to 5.5V. Its 16 outputs are grouped into four banks of four, each controlled by a dedicated OE pin (1OE–4OE), supporting granular bus control and live insertion.
Each output includes matched 30Ω series resistance in both pull-up and pull-down paths-verified in schematic SW00007-reducing ringing and eliminating need for external termination resistors. Bus-hold circuitry maintains stable logic states on unused inputs without external components, and power-up 3-State ensures outputs remain high-impedance during supply ramp-up.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply Range | 2.3–2.7V or 3.0–3.6V - Enables interoperability with both 2.5V and 3.3V system domains |
| Output Drive Strength | ±12mA at 3.3V - Sufficient to drive 50Ω transmission lines directly without external buffers |
| Propagation Delay (tPLH/tPHL) | 2.2–2.6ns typical at 3.3V, CL = 50pF - Supports >300MHz bus toggle rates in point-to-point configurations |
| Input Voltage Range (VI) | 0–5.5V - Full 5V tolerance allows direct interfacing with legacy TTL and CMOS logic |
| Bus-Hold Current (IHOLD) | ±75 to ±130µA at 3.3V - Actively retains last valid logic state on floating inputs, removing need for pull-up/pull-down resistors |
| Termination Resistance | 30Ω series per output - Integrated impedance matching reduces overshoot/ringing on stubbed or unterminated traces |
| ICCZ Quiescent Current | 100µA max with outputs disabled - Minimizes standby power in large-scale bus systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit inverting buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ALVTH162240DGGR | TI part with identical 16-bit inverting 3-State function, 30Ω termination, and bus-hold; operates at 2.3–3.6V but specifies only 3.3V timing (no 2.5V characterization). | Lacks published 2.5V AC/DC specs; not validated for mixed-voltage 2.5V-core/5V-I/O systems requiring full 2.5V-range compliance. | Select when design uses only 3.3V VCC and TI supply chain preference applies; verify timing margin at worst-case temperature. |
| 74LVT162240DGG,11 | Same footprint and pinout, but lacks integrated 30Ω termination and bus-hold; requires external 33Ω resistors and pull-ups for equivalent functionality. | Increases BOM count by ≥32 passive components and adds layout complexity; higher risk of signal integrity issues on unterminated lines. | Select only if cost sensitivity outweighs design simplicity and signal integrity requirements; not recommended for new designs targeting high-speed buses. |
Compared with SN74ALVTH162240DGGR and 74LVT162240DGG,11, the 74ALVT162240DGG,11 uniquely provides full 2.5V/3.3V operational validation, integrated termination, and bus-hold in one device-reducing component count, layout risk, and qualification effort for mixed-voltage embedded bus interfaces.

FAQ
What is the exact supply voltage range supported by the 74ALVT162240DGG,11?
The 74ALVT162240DGG,11 operates across two validated ranges: 2.3V to 2.7V for 2.5V systems and 3.0V to 3.6V for 3.3V systems. Both ranges support full 5V-tolerant I/O (0–5.5V input voltage), and all DC/AC specifications-including propagation delay, drive strength, and bus-hold current-are characterized across the full temperature range (–40°C to +85°C) for each VCC band.
Does the 74ALVT162240DGG,11 require external termination resistors?
No. The 74ALVT162240DGG,11 integrates 30Ω series resistance in both pull-up and pull-down paths of every output, as confirmed in the schematic diagram SW00007 and Quick Reference Data table. This eliminates the need for external 33Ω resistors typically used for source termination on high-speed buses, reducing BOM count and PCB routing complexity.
How does bus-hold functionality work on the 74ALVT162240DGG,11 inputs?
The 74ALVT162240DGG,11 implements active bus-hold circuitry on all 16 A-inputs (1A0–4A3), providing ±75µA to ±130µA overdrive current to retain the last valid logic state when inputs float. This is measured per DC Electrical Characteristics tables and removes the need for external pull-up or pull-down resistors-critical for unused or dynamically disconnected bus lines.
Can the 74ALVT162240DGG,11 be used in hot-swap applications?
Yes. The 74ALVT162240DGG,11 supports live insertion/extraction per its Features list and includes power-up 3-State behavior-ensuring all outputs remain high-impedance until VCC stabilizes. Combined with 2000V HBM ESD protection and robust absolute maximum ratings (e.g., VI up to 7.0V), it meets industrial hot-swap requirements without additional protection circuitry.
What is the pin-compatible alternative if 74ALVT162240DGG,11 is unavailable?
The 74LVT162240DGG,11 shares identical pinout and package (SOT362-1 TSSOP48) but lacks integrated 30Ω termination and bus-hold. Using it requires adding 32 external passives (16×33Ω resistors + 16×pull-ups), increasing layout complexity and compromising signal integrity. No true pin-compatible replacement offers the same integrated features; redesign or qualification of SN74ALVTH162240DGGR is required.
