Product details
Overview
74ALVT162244DGG:11 from NXP Semiconductors (formerly Philips) is a 16-bit non-inverting 3-State buffer/driver with integrated 30Ω series output termination, designed for 2.5V or 3.3V VCC operation and 5V-tolerant I/O. It delivers ±12mA drive strength, supports bus-hold on all data inputs, and operates across –40°C to +85°C - used in high-speed memory address drivers and backplane bus interfaces.
For engineers reviewing the 74ALVT162244DGG:11 datasheet, 74ALVT162244DGG:11 pinout, 74ALVT162244DGG:11 application, or 74ALVT162244DGG:11 equivalent, key selection criteria include its dual-voltage supply support (2.5V/3.3V), built-in 30Ω output series resistance eliminating external terminators, bus-hold functionality, and 48-pin TSSOP package compatibility with high-density PCB layouts.
Technical Context
The 74ALVT162244DGG:11 implements four independent 4-bit non-inverting 3-State buffers, each with dedicated output-enable (OE) control. Its BiCMOS architecture enables fast propagation delays (as low as 2.2ns at 3.3V) while maintaining TTL-compatible input thresholds and 5V I/O tolerance.
All 16 outputs integrate matched 30Ω series resistors in both high and low states - a design specifically intended to suppress transmission-line ringing in parallel bus systems. Bus-hold circuitry on all 16 data inputs eliminates need for external pull-up/pull-down resistors on unused lines, simplifying system-level design and improving noise immunity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply Range | 2.3–2.7V or 3.0–3.6V - dual-voltage operation enables interoperability between 2.5V and 3.3V logic domains |
| Output Drive | ±12mA - sufficient to drive terminated 50Ω transmission lines without external buffers |
| Propagation Delay | 2.2ns (typ, 3.3V, CL=50pF) - supports >300MHz bus signaling in point-to-point configurations |
| Input Voltage Range | –0.5V to +5.5V - full 5V-tolerant I/O allows safe interfacing with legacy 5V systems |
| Bus-Hold Current | ±75µA to ±140µA (3.3V) - actively maintains last-valid logic state on floating inputs without external components |
| Termination Resistance | 30Ω (integrated series) - matches common PCB trace impedances, reducing overshoot/ringing without discrete resistors |
| Quiescent Supply Current | 40µA (2.5V) / 70µA (3.3V) with outputs disabled - ultra-low static power in standby mode |

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 with identical 16-bit non-inverting 3-State function, 30Ω termination, and 2.3–3.6V operation; slightly higher IOL/IOH (±24mA vs ±12mA) | Higher drive strength suits longer stubs or heavier capacitive loads (>75pF), but increases crosstalk risk in dense layouts | Select SN74ALVTH162244DGGR only when ≥24mA output current is required; otherwise 74ALVT162244DGG:11 offers better noise margin and lower power |
| 74LVT162244DGG,11 | NXP variant without bus-hold inputs; same pinout, 30Ω termination, and 2.5V/3.3V operation; lacks internal input hold circuitry | Requires external pull-up/down resistors on unused inputs - adds BOM cost and board area, unsuitable for dynamically reconfigured buses | Choose 74LVT162244DGG,11 only in fixed-configuration systems where all inputs are always driven; 74ALVT162244DGG:11 preferred for flexibility and reliability |
Compared with SN74ALVTH162244DGGR and 74LVT162244DGG,11, the 74ALVT162244DGG:11 uniquely balances moderate drive strength, integrated bus-hold, and low quiescent current - making it optimal for space-constrained, dynamically configured 16-bit buses where signal integrity and input robustness are prioritized over maximum fanout.

FAQ
What supply voltages does the 74ALVT162244DGG:11 support?
The 74ALVT162244DGG:11 operates from either 2.5V ±0.2V (2.3V–2.7V) or 3.3V ±0.3V (3.0V–3.6V) VCC. It is not rated for 5V VCC, but all inputs and outputs tolerate up to 5.5V - enabling safe interfacing with 5V systems while powered from lower-voltage rails. This dual-range support is explicitly defined in the Recommended Operating Conditions table.
Does the 74ALVT162244DGG:11 require external termination resistors?
No. The 74ALVT162244DGG:11 integrates 30Ω series resistors in both high and low output states, as confirmed in the Features list and schematic diagram. This eliminates the need for external termination resistors on all 16 outputs - a key differentiator versus standard buffers like the 74LVT162244. The internal resistance is matched to typical PCB trace impedances to reduce ringing.
How does bus-hold functionality work on the 74ALVT162244DGG:11?
The 74ALVT162244DGG:11 provides bus-hold on all 16 data inputs (1A0–4A3), with overdrive currents of ±75µA to ±140µA depending on VCC and input voltage. This active feedback circuit maintains the last-valid logic state when inputs float - verified in the DC Electrical Characteristics tables. It removes the need for external pull-up or pull-down resistors in partially populated or dynamically reconfigured bus systems.
Is the 74ALVT162244DGG:11 pin-compatible with other 48-pin TSSOP logic buffers?
The 74ALVT162244DGG:11 uses a standardized 48-pin TSSOP footprint (SOT362-1) with 0.5 mm pitch, matching industry-layout conventions. However, pin assignments - especially the distribution of VCC, GND, OE, and I/O groups - are specific to this device. Direct replacement requires verification of logic function, OE polarity, and output drive characteristics; it is not a generic drop-in for unrelated 48-pin buffers.
What is the maximum operating temperature range for the 74ALVT162244DGG:11?
The 74ALVT162244DGG:11 is specified for operation from –40°C to +85°C, as stated in the Ordering Information and Recommended Operating Conditions sections. This industrial temperature grade is validated across all electrical parameters including propagation delay, output drive, and bus-hold performance - making it suitable for embedded control, networking, and industrial automation environments.
