Product details
Overview
74LVT162240ADL,118 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 distribution, and bidirectional 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 74LVT162240ADL,118 datasheet, 74LVT162240ADL,118 pinout, 74LVT162240ADL,118 application, or 74LVT162240ADL,118 equivalent, this device delivers deterministic noise suppression via on-die 30 Ω termination, supports mixed-voltage interfacing (3.3 V core / 5 V bus), and enables live insertion in backplane systems without bus contention.
Technical Context
This BiCMOS buffer implements true inverting logic across 16 channels grouped into four 4-bit sections, each controlled by a dedicated active-low output enable (1OE–4OE). Its internal 30 Ω series resistance per output path suppresses ringing and overshoot on transmission lines up to 10 ns/V input transition rates.
Bus-hold circuitry maintains valid logic states on unused inputs without external components, while power-up 3-state behavior prevents output contention during power sequencing. The device operates across -40 °C to +85 °C with supply voltage tolerance from 2.7 V to 3.6 V and interfaces seamlessly to 5 V systems via TTL-level inputs and overvoltage-tolerant outputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply Range | 2.7 V to 3.6 V - Ensures stable operation across industrial-grade 3.3 V rail tolerances. |
| Output Drive | ±12 mA - Sustains signal integrity when driving 50 Ω transmission lines or multiple CMOS loads. |
| Propagation Delay | 0.5–4.2 ns (typ. 2.6 ns at 3.3 V) - Enables sub-5 ns timing budgets in high-speed address/data buses. |
| Input Voltage Range | 0 V to 5.5 V - Allows direct connection to 5 V logic without level shifters. |
| Termination Resistance | 30 Ω series per output - Eliminates need for external source-series resistors in point-to-point or stubbed bus topologies. |

Key Features
| Feature | Design Value |
|---|---|
| Integrated 30 Ω output termination | Removes requirement for 16 discrete series resistors, reducing BOM count and PCB area in memory/clock driver layouts. |

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 termination; requires external 33 Ω resistors; lower drive (±24 mA); 1.65–3.6 V supply. | Better suited for ultra-low-power systems where termination is added selectively; lacks bus-hold. | Select if supply voltage flexibility down to 1.65 V is required and board space permits discrete termination. |
| 74ALVCH162240QFG | Higher speed (tPD = 2.1 ns typ); no built-in termination; 1.65–3.6 V; no bus-hold; different pinout (LQFP). | Preferred for timing-critical FPGA I/O expansion where minimal propagation skew dominates over noise suppression. | Choose when sub-2.5 ns delay is mandatory and external termination + pull-ups are acceptable. |
Compared with SN74LVC16240ADGGR and 74ALVCH162240QFG, the 74LVT162240ADL,118 uniquely combines on-die 30 Ω termination, bus-hold, and 5 V-tolerant I/O in a single TSSOP48 package-reducing design complexity for noise-sensitive, mixed-voltage bus interfaces without sacrificing drive strength or thermal margin.

FAQ
Does the 74LVT162240ADL,118 require external termination resistors?
No. Each output integrates a precise 30 Ω series resistor, eliminating the need for external source-series termination in standard 50 Ω or 75 Ω transmission line environments. This reduces PCB footprint, BOM cost, and layout sensitivity to trace impedance variations.
Can the 74LVT162240ADL,118 safely interface with 5 V logic systems?
Yes. Its inputs accept 0–5.5 V and outputs tolerate 5 V bus connections without damage, enabling direct interfacing with legacy 5 V peripherals. The device operates from a 3.3 V supply while maintaining TTL-compatible thresholds and overvoltage-safe I/O structures.
How does the bus-hold feature simplify system design?
Bus-hold circuitry actively maintains the last valid logic state on unconnected or unterminated inputs using ±75 μA to ±135 μA feedback current-removing the need for 16 external pull-up/pull-down resistors and preventing floating-input-induced glitches or increased EMI.
What is the thermal performance of the TSSOP48 package under full 16-bit drive?
At 3.3 V and ambient 85 °C, maximum power dissipation is 320 mW (ICC = 0.12 mA quiescent + 16 × 12 mA × 0.8 V typical VOL drop). The TSSOP48's 8-GND-pin layout and copper-thief pads support junction temperatures ≤125 °C with standard 2-layer PCB cooling.
