Product details
Overview
74LVT162240ADGG:11 from Nexperia is a 3.3 V, 16-bit inverting buffer/driver with integrated 30 Ω series termination resistors on all outputs, designed for high-speed bus driving in memory address, clock, and data bus applications. It features four independent 3-state output enable inputs (1OE–4OE), ±12 mA drive capability, TTL-compatible I/O, and bus-hold inputs eliminating external pull-ups.
For engineers reviewing the 74LVT162240ADGG:11 datasheet, 74LVT162240ADGG:11 pinout, 74LVT162240ADGG:11 application, or 74LVT162240ADGG:11 equivalent, this device is selected for noise-sensitive 3.3 V/5 V mixed-signal bus interfaces requiring controlled-impedance drive, fast propagation (<4.2 ns), and live insertion support without external termination.
Technical Context
The 74LVT162240ADGG:11 implements a BiCMOS architecture optimized for 3.3 V operation while maintaining full 5 V input/output tolerance. Its four independent 3-state control groups (each enabling four outputs) allow granular bus segment management, and its built-in 30 Ω series output resistance matches typical PCB trace impedance to suppress ringing and overshoot.
Bus-hold circuitry actively maintains logic state on unused inputs at 3 V supply, eliminating floating nodes and external biasing. Power-up 3-state behavior ensures outputs remain high-impedance during power ramp, preventing bus contention at system startup.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 2.7 V to 3.6 V - Ensures stable operation across industrial 3.3 V rail tolerances. |
| Output Drive | ±12 mA - Sufficient to drive 50 Ω transmission lines or multiple TTL loads without external buffers. |
| Propagation Delay | 2.6 ns typical (VCC = 3.3 V) - Enables reliable timing in >200 MHz bus systems with tight skew budgets. |
| Input Voltage Range | 0 V to 5.5 V - Allows direct interfacing with legacy 5 V logic without level shifters. |

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 |
|---|---|---|---|
| SN74LVC16240ADGGR | No integrated 30 Ω termination; requires external series resistors; lower drive (±24 mA); 1.65–3.6 V VCC range. | Better suited for low-voltage portable systems but adds 16 discrete resistors and increases layout complexity. | Select when operating below 2.7 V or when higher drive strength is required and termination can be added externally. |
| 74ALVT162240DGGR | Faster propagation (1.8 ns typ); higher ICC (0.25 mA typ); same 30 Ω termination and pinout; −40 °C to +85 °C rating. | Used in ultra-low-latency applications like high-speed test instrumentation where sub-2 ns delay is critical. | Select only when propagation delay must be reduced by ≥30% and additional supply current is acceptable. |
Compared with SN74LVC16240ADGGR, the 74LVT162240ADGG:11 saves board space and improves signal integrity via monolithic termination; compared with 74ALVT162240DGGR, it trades 0.8 ns speed for lower static power and broader voltage margin-ideal for cost- and thermally constrained industrial bus drivers.

FAQ
Can the 74LVT162240ADGG:11 operate reliably with a 2.5 V supply?
No. The recommended operating VCC range is 2.7 V to 3.6 V per Table 5 of the datasheet. At 2.5 V, VIH and VOL specifications fall outside guaranteed limits, risking incorrect logic interpretation and excessive output voltage deviation. Operation below 2.7 V is not characterized or supported.
Does the 30 Ω termination apply to both HIGH and LOW output states?
Yes. Figure 3 explicitly shows symmetrical 27 Ω pull-up and pull-down structures (rounded to 30 Ω in marketing documentation), meaning the series resistance is present in both sourcing and sinking paths-ensuring matched rise/fall edge control and consistent impedance matching regardless of output logic level.
How does bus-hold functionality interact with externally pulled inputs?
Bus-hold circuitry activates only when input voltage is near the switching threshold (typically 0.8–2.0 V). If an input is strongly pulled to GND or VCC (e.g., via ≤1 kΩ resistor), bus-hold current (±75–135 μA) is overridden and has no effect-the external net dominates. Bus-hold serves only floating or weakly biased inputs.
Is thermal pad connection required for the TSSOP48 package?
No. The SOT362-1 (TSSOP48) package used for 74LVT162240ADGG:11 has no exposed thermal pad. Thermal dissipation relies on standard leadframe conduction through pins 7, 18, 31, 42 (VCC) and the eight GND pins-no PCB thermal slug or solder paste under-body is needed or specified.
