Product details
Overview
74LVT162240ADGG,51 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 input thresholds, and operates across –40 °C to +85 °C.
For engineers reviewing the 74LVT162240ADGG,51 datasheet, 74LVT162240ADGG,51 pinout, 74LVT162240ADGG,51 application, or 74LVT162240ADGG,51 equivalent, this device is selected for noise-sensitive 3.3 V/5 V mixed-signal bus interfaces where internal termination eliminates external resistors and bus-hold inputs prevent floating states.
Technical Context
The 74LVT162240ADGG,51 implements a BiCMOS architecture enabling fast propagation delays (tPLH/tPHL ≤ 4.2 ns at 3.3 V) while maintaining TTL-level compatibility and 5 V-tolerant inputs. Its four independent 3-state control groups (each managing four outputs) support segmented bus control without contention.
Each output integrates matched 30 Ω series resistors in both pull-up and pull-down paths-verified in Fig. 3 schematic-reducing ringing and overshoot on transmission lines. Bus-hold circuitry on all data inputs (IBHL = 75–135 μA at 3 V) actively maintains last-valid logic state without external biasing.
Key Specifications

|---|---|
| VCC Supply | 2.7 V to 3.6 V - ensures stable operation in modern 3.3 V systems with ±0.3 V tolerance margin |
| Output Drive | ±12 mA - sufficient to drive 50 Ω transmission lines or multiple TTL loads without external buffers |
| Propagation Delay | 2.6 ns typical (tPLH/tPHL at 3.3 V) - enables >200 MHz bus timing in point-to-point configurations |

Applications
| Memory Address Buffering | PCI/PCIe Slot Interface |
|---|---|
|
Use Scenario: Driving 16-bit address lines from a microcontroller to SRAM or Flash memory with stub-free routing. IC Role / Device Role / Timing Role: Inverting buffer with controlled edge rates and on-die termination, placed adjacent to memory device. Use Value: 30 Ω series resistance suppresses reflections on 50 Ω traces, reducing setup/hold timing violations by up to 1.2 ns per transition. |
Use Scenario: Level-shifting and buffering address/data strobes between 3.3 V host controller and 5 V add-in card in industrial PCI slots. IC Role / Device Role / Timing Role: Bidirectional interface buffer with 5 V-tolerant inputs and 3.3 V outputs, managed via per-group OE control. Use Value: Eliminates need for discrete level translators and termination networks, cutting interconnect delay by 0.8 ns versus discrete resistor+buffer solutions. |
| Backplane Clock Distribution | Hot-Swappable Module Interface |
|
Use Scenario: Distributing low-skew clock signals across a 12-layer backplane to multiple FPGA clock inputs. IC Role / Device Role / Timing Role: Inverting clock driver with matched output impedance, used in fanout configuration with daisy-chained loads. Use Value: Matched 30 Ω output resistance minimizes signal integrity degradation over 15 cm FR4 traces, maintaining <15 ps skew across 16 outputs. |
Use Scenario: Interfacing hot-pluggable I/O modules to a central controller where inputs may float during insertion/removal. IC Role / Device Role / Timing Role: Input conditioning and bus isolation buffer with bus-hold and power-up 3-state behavior. Use Value: Bus-hold current prevents metastability on unconnected inputs during live insertion, and power-up 3-state avoids bus glitches during module power ramp. |
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; 3.3 V only I/O; no bus-hold | Suitable for cost-sensitive designs where board space permits discrete termination and inputs are always driven | Select when BOM simplicity is secondary to lowest unit cost and full 5 V tolerance is unnecessary |
| 74ALVCH162240PAG | Higher drive (±24 mA); no built-in termination; supports 1.65–3.6 V VCC; no bus-hold | Better for driving longer traces or heavier capacitive loads (>30 pF), but adds external termination complexity | Choose when higher output current is required and system-level termination can be implemented externally |
Compared with SN74LVC16240ADGGR and 74ALVCH162240PAG, the 74LVT162240ADGG,51 uniquely combines on-die 30 Ω termination, bus-hold inputs, and 5 V-tolerant operation-enabling single-component replacement of buffer+resistor+pull-up solutions in industrial bus interfaces.

FAQ
What is the purpose of the 30 Ω series resistors on each output?
The 30 Ω resistors are integrated into both pull-up and pull-down paths of every output to match typical PCB trace impedances (e.g., 50 Ω). This reduces signal reflections, overshoot, and ringing on high-speed buses-eliminating the need for eight external 33 Ω resistors and improving signal integrity without layout compromises.
Can the 74LVT162240ADGG,51 safely interface with 5 V logic inputs?
Yes-the device accepts input voltages from 0 V to 5.5 V while operating at 3.3 V VCC. Its TTL-compatible input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) and ESD-hardened structure allow direct connection to 5 V CMOS or TTL outputs without level shifters or clamping diodes.
How does the bus-hold function operate, and what current does it provide?
Bus-hold circuitry actively maintains the last-valid logic state on each data input using feedback transistors. At VCC = 3 V, it sources or sinks 75–135 μA (IBHL/IBHH) to hold inputs HIGH or LOW-preventing floating states during power-up, hot-swap, or unconnected test points without external pull-up/down resistors.
Is the 74LVT162240ADGG,51 pin-compatible with other 74-series 16-bit buffers?
No-it uses a proprietary 48-pin TSSOP (SOT362-1) pinout optimized for thermal and signal integrity, differing from standard SSOP or TSSOP packages of similar-function devices like 74LVC16240. Pin mapping must be verified against Table 2 in the datasheet; direct substitution requires PCB redesign.
