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 features four independent 3-State output enables (1OE–4OE), ±12mA drive capability, bus-hold inputs, and operates across –40°C to +85°C - ideal for high-speed memory address and clock bus driving in mixed-voltage systems.
For engineers reviewing the 74ALVT162240DGG:11 datasheet, 74ALVT162240DGG:11 pinout, 74ALVT162240DGG:11 application, or 74ALVT162240DGG:11 equivalent, this page delivers verified electrical specs, TSSOP-48 package details, bus-hold behavior, propagation delay (2.2 ns typical at 3.3V), and real-world substitution guidance - all grounded in the original Philips 1998 product specification.
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-bit inverting logic is partitioned into four 4-bit groups, each controlled by a dedicated OE pin (1OE–4OE), allowing granular bus segment control.
Each output integrates matched 30Ω series resistance in both pull-up and pull-down paths - eliminating external termination resistors and reducing transmission-line ringing in stub-loaded buses. Bus-hold circuitry on all data inputs maintains valid logic states without external pull-ups, supporting live insertion/extraction.

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 uses ALVT process variant; identical 30Ω termination, but tighter tPLH/tPHL spec (1.9 ns typ @ 3.3V) and higher IOL/IOH (±24mA) | Supports higher fan-out and longer traces; requires updated thermal layout due to higher ICCZ (0.2 mA vs 0.1 mA) | Select when driving >10 pF load per line or requiring <2 ns propagation consistency across temperature |
| 74LVT162240DGG,11 | Same Philips/NXP die but LVT version: no bus-hold inputs, no power-up 3-State, and 25Ω termination instead of 30Ω | Suitable only where external pull-ups are acceptable and hot-swap is not required; lower cost but higher BOM complexity | Select only if bus-hold and power-up 3-State are unnecessary and existing designs use LVT family qualification |
Compared with SN74ALVTH162240DGGR, the 74ALVT162240DGG:11 offers proven bus-hold robustness and lower quiescent current, while the 74LVT162240DGG,11 trades feature set for legacy compatibility - making the 74ALVT162240DGG:11 optimal for new designs prioritizing reliability and component count reduction.

FAQ
What is the maximum operating frequency supported by the 74ALVT162240DGG:11?
The 74ALVT162240DGG:11 does not specify a maximum clock frequency directly, but its typical propagation delay of 2.2 ns at 3.3V (CL = 50 pF) supports reliable operation up to approximately 200 MHz in point-to-point configurations. Actual usable frequency depends on trace length, loading, and termination - the integrated 30Ω series resistance helps maintain signal integrity at these speeds without external components. For 74ALVT162240DGG:11-based designs targeting >150 MHz, controlled-impedance routing and minimized stub lengths are recommended.
Does the 74ALVT162240DGG:11 require external pull-up resistors on unused inputs?
No, the 74ALVT162240DGG:11 includes bus-hold circuitry on all data inputs (1A0–4A3), which actively maintains the last-valid logic state without external components. This feature eliminates the need for pull-up or pull-down resistors on unconnected or unterminated inputs - a key advantage over standard LVT or LVTH buffers. The bus-hold current ranges from ±75 µA to ±140 µA at 3.3V, ensuring robust state retention even under noise or slow slew-rate conditions. This behavior is intrinsic to the 74ALVT162240DGG:11 and requires no configuration.
Can the 74ALVT162240DGG:11 be used with a 2.5V supply and 5V inputs simultaneously?
Yes, the 74ALVT162240DGG:11 is explicitly rated for 2.5V ±0.2V VCC operation while accepting input voltages up to 5.5V - making it fully compatible with mixed-voltage systems. When powered at 2.5V, its inputs tolerate 5V signals without damage or clamping, and its outputs swing rail-to-rail (0V to 2.5V) with ±12mA drive strength. This capability is confirmed in the "Recommended Operating Conditions" and "DC Electrical Characteristics (2.5V range)" sections of the Philips 1998 datasheet for the 74ALVT162240DGG:11.
What is the purpose of the four separate output enable (OE) pins on the 74ALVT162240DGG:11?
The 74ALVT162240DGG:11 provides four independent active-low output enables (1OE–4OE), each controlling a distinct 4-bit output group (e.g., 1OE enables 1Y0–1Y3). This architecture allows selective activation of bus segments - essential for multi-master arbitration, partial bus isolation, and hot-plug scenarios. Unlike single-OE buffers, the 74ALVT162240DGG:11 enables dynamic reconfiguration of data paths without disabling the entire 16-bit interface, improving system flexibility and reducing contention risk in complex backplane or modular designs.
How does the integrated 30Ω termination in the 74ALVT162240DGG:11 improve signal integrity?
The 74ALVT162240DGG:11 integrates 30Ω series resistance in both pull-up and pull-down output paths - matching typical PCB trace impedances (40–70Ω) to suppress reflections at the source. This reduces overshoot, undershoot, and ringing on stub-loaded buses such as memory address lines or clock nets. By embedding termination directly in the silicon, the 74ALVT162240DGG:11 eliminates 32 discrete resistors, saving board space and assembly cost while guaranteeing matched impedance per output - a design advantage validated in Philips' application notes on high-speed bus driving.
