Product details
Overview
74ALVT162241DL,118 from NXP Semiconductors (formerly Philips) is a 2.5V/3.3V 16-bit 3-state buffer/driver with integrated 30Ω series output termination resistors, designed for high-speed bus driving in memory address, clock, and data bus applications. It features four independent output enables (1OE–4OE), ±12mA drive strength, 5V-tolerant I/O, and bus-hold inputs eliminating external pull-ups.
For engineers reviewing the 74ALVT162241DL,118 datasheet, 74ALVT162241DL,118 pinout, 74ALVT162241DL,118 application, or 74ALVT162241DL,118 equivalent, this device supports robust signal integrity on terminated transmission lines without external resistors, delivers sub-3.6ns propagation delay at 3.3V, and enables live insertion in backplane and hot-swap systems.
Technical Context
The 74ALVT162241DL,118 implements BiCMOS logic with dual-voltage operation (2.3–2.7V or 3.0–3.6V VCC) while maintaining full 5V input tolerance and 5V-bus-compatible outputs. Its architecture integrates 30Ω series resistance in both high- and low-side output stages to suppress overshoot/undershoot on transmission lines.
Each of its four 4-bit output groups (1Y0–1Y3 through 4Y0–4Y3) is independently controlled by dedicated OE pins (1OE–4OE), enabling granular bus partitioning. Bus-hold circuitry on all 16 data inputs maintains valid logic states on floating inputs without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Operating Range | 2.3–2.7V or 3.0–3.6V - Dual-supply compatibility enables use in mixed-voltage 2.5V/3.3V systems with 5V I/O interfacing. |
| Propagation Delay (tPLH/tPHL) | 2.2ns (typ) at 3.3V - Enables >400MHz bus timing margins for high-speed address/data routing. |
| Output Drive Strength | ±12mA - Sustains clean signal edges into 50Ω loads without external buffering. |
| Integrated Termination | 30Ω series resistor per output - Eliminates need for discrete 33Ω resistors, reducing BOM count and PCB area. |
| Input Voltage Range | –0.5V to +5.5V - Fully 5V-tolerant inputs allow direct connection to legacy 5V logic without level shifters. |
| Bus-Hold Current | ±75µA (min) at 3.0V - Actively holds unused inputs at last-valid state, preventing metastability and EMI. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 48, 25, 24 | 1OE, 2OE, 3OE, 4OE | Active-low output enable controls for four independent 4-bit output groups - enables selective bus gating without global disable. |
| 47–43, 41–37, 36–32, 30–26 | 1A0–1A3, 2A0–2A3, 3A0–3A3, 4A0–4A3 | 16 data inputs with bus-hold - eliminates external pull-up/pull-down resistors on unused or unterminated inputs. |
| 2–6, 8–12, 13–17, 19–23 | 1Y0–1Y3, 2Y0–2Y3, 3Y0–3Y3, 4Y0–4Y3 | 16 3-state outputs with integrated 30Ω series termination - reduces reflection-induced ringing on PCB traces up to 15 cm. |

Key Features
| Feature | Design Value |
|---|---|
| Live insertion/extraction support | Power-up 3-state and I/O clamp diodes allow safe hot-plug into powered backplanes without damaging connected logic. |
| 5V I/O compatibility | Inputs accept 0–5.5V; outputs drive 5V buses directly - enables seamless interface between 2.5V/3.3V ASICs and legacy 5V peripherals. |
| No bus current loading at 5V | Outputs draw zero steady-state current when tied to 5V bus in high-impedance state - prevents unintended bus contention or voltage droop. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit terminated buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ALVTH162241DGGR | TI part uses ALVT process but lacks integrated 30Ω termination; requires external resistors for line matching. | Higher BOM cost and PCB area due to 16 added 33Ω resistors; no bus-hold on inputs. | Select only if existing design already uses external termination and requires TI's qualification profile. |
| 74LVT162241DGG,118 | NXP variant operates at 3.3V only (no 2.5V mode); identical pinout and bus-hold, but no integrated termination resistors. | Requires full external termination network; suitable only where board layout allows discrete resistor placement near each output. | Choose when 2.5V operation is unnecessary and cost sensitivity favors lower unit price over BOM simplification. |
Compared with SN74ALVTH162241DGGR and 74LVT162241DGG,118, the 74ALVT162241DL,118 uniquely combines dual-supply operation, integrated 30Ω termination, and bus-hold in one package-reducing component count by ≥32 parts and enabling cleaner signal integrity in space-constrained industrial and telecom designs.

FAQ
What supply voltages does the 74ALVT162241DL,118 support?
The 74ALVT162241DL,118 operates at two distinct VCC ranges: 2.3–2.7V for 2.5V systems and 3.0–3.6V for 3.3V systems. It maintains full 5V input tolerance and 5V-bus-compatible outputs across both ranges. This dual-voltage capability allows the 74ALVT162241DL,118 to serve as a bridge between legacy 5V peripherals and modern low-voltage controllers without external level shifters.
Does the 74ALVT162241DL,118 require external termination resistors?
No, the 74ALVT162241DL,118 integrates 30Ω series resistors in both high- and low-side output drivers, making external termination resistors unnecessary for standard 50Ω PCB traces. This feature is explicitly confirmed in the datasheet's DESCRIPTION and FEATURES sections and eliminates up to 16 discrete components per device, reducing BOM cost and layout complexity.
How does bus-hold functionality work on the 74ALVT162241DL,118?
The 74ALVT162241DL,118 provides bus-hold on all 16 data inputs (1A0–4A3), actively maintaining the last-valid logic state when inputs float. The datasheet specifies ±75µA minimum hold current at 3.0V, sufficient to prevent metastability and EMI in unterminated or high-impedance nodes. This eliminates the need for external pull-up or pull-down resistors on unused inputs.
Is the 74ALVT162241DL,118 suitable for hot-swap applications?
Yes, the 74ALVT162241DL,118 supports live insertion/extraction per its datasheet FEATURES section. Key enablers include power-up 3-state behavior (outputs remain high-impedance until VCC stabilizes), I/O clamp diodes, and robust ESD/latch-up protection (2000V HBM, 500mA latch-up rating). These features make the 74ALVT162241DL,118 appropriate for modular backplane and telecom shelf designs requiring zero-downtime maintenance.
What is the pin-compatible alternative if 74ALVT162241DL,118 is unavailable?
No pin-compatible drop-in replacement exists for the 74ALVT162241DL,118 due to its unique integration of 30Ω termination, bus-hold, and dual-voltage operation. The closest alternatives-SN74ALVTH162241DGGR and 74LVT162241DGG,118-share the same pinout but lack integrated termination. Substituting either requires redesigning the termination network and verifying bus-hold behavior, so the 74ALVT162241DL,118 remains the optimal choice for new designs prioritizing signal integrity and BOM reduction.
