Product details
Overview
74LVT162240ADGG,11 from Nexperia is a 3.3 V 16-bit inverting 3-state 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 output-enable inputs (1OE–4OE), ±12 mA drive strength, TTL-compatible I/O, and operates across –40 °C to +85 °C.
For engineers reviewing the 74LVT162240ADGG,11 datasheet, 74LVT162240ADGG,11 pinout, 74LVT162240ADGG,11 application, or 74LVT162240ADGG,11 equivalent, this device is selected for noise-sensitive 3.3 V/5 V mixed-signal bus interfaces requiring built-in termination, bus-hold inputs, and live-insertion capability without external resistors.
Technical Context
The device implements a BiCMOS architecture enabling TTL-level compatibility while operating at 3.3 V supply, supporting bidirectional interfacing with 5 V systems. Its four 4-bit output groups are independently controlled by active-low OE pins, allowing granular bus partitioning and power sequencing.
Each output integrates matched 30 Ω series resistors in both pull-up and pull-down paths-verified per Fig. 3 schematic-reducing ringing and overshoot on transmission lines up to 10 ns/V input transition rates. Bus-hold circuitry on all data inputs eliminates external biasing, maintaining valid logic states during floating conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VCC) | 2.7 V to 3.6 V - ensures stable operation across industrial 3.3 V rail tolerances |
| Output Drive Strength | ±12 mA - supports direct connection to 50 Ω transmission lines without external drivers |
| Propagation Delay (tPLH/tPHL) | 0.5 ns (min) to 4.2 ns (max) at 3.3 V - enables >200 MHz bus timing margins |
| Input/Output Voltage Levels | TTL-compatible VIH ≥ 2.0 V, VIL ≤ 0.8 V - interoperable with legacy 5 V logic families |
| Bus-Hold Current | IBHL = 75–135 μA, IBHH = –75 to –135 μA - actively retains input state without pull-ups |
| Termination Resistance | 30 Ω series per output - eliminates need for discrete 33 Ω SMT resistors on PCB |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - withstands handling in standard assembly environments |

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; 24 mA drive; 1.65–3.6 V VCC range | Requires external 33 Ω series resistors; better for ultra-low voltage systems | Select when lower supply voltage (<2.7 V) or higher drive current is needed, and board space permits external termination |
| 74ALVT162240DGGR | Higher speed (tPD = 2.1 ns typ); same 30 Ω termination; 2.3–3.6 V VCC | Narrower voltage range; not rated for 5 V input tolerance | Choose for sub-3 ns timing-critical buses where 5 V interfacing is unnecessary |
Compared with SN74LVC16240ADGGR and 74ALVT162240DGGR, the 74LVT162240ADGG,11 uniquely combines 5 V input tolerance, integrated 30 Ω termination, and industrial temperature range-making it optimal for mixed-voltage industrial backplanes where reliability and BOM simplification are prioritized over marginal speed gains.

FAQ
Can 74LVT162240ADGG,11 drive a 50 Ω transmission line directly?
Yes. Each output integrates a matched 30 Ω series resistor, enabling direct connection to 50 Ω PCB traces without external termination. Measured propagation delay (2.6 ns typ at 3.3 V) and ±12 mA drive ensure clean edge integrity into 50 Ω loads per Fig. 4 and Table 7 specifications.
Does this device support hot-swap in backplane applications?
Yes. It supports live insertion/extraction per datasheet Section 2, featuring power-up 3-state, input clamping (–0.5 V to +7.0 V), and JESD17 latch-up immunity (>500 mA). These characteristics prevent bus contention and damage during hot-plug events in modular systems.
How does the bus-hold function eliminate external pull-up resistors?
Bus-hold circuitry provides active feedback: IBHL = 75–135 μA (LOW) and IBHH = –75 to –135 μA (HIGH) at 3 V, maintaining valid logic states on floating inputs. This replaces discrete 10–100 kΩ pull-ups, reducing component count and board space per Section 2 and Table 6.
What is the maximum clock frequency supported for reliable operation?
Based on tPLH/tPHL = 4.2 ns max (at 3.3 V) and 10 ns/V input transition rate limit, the device reliably supports bus toggle rates up to 120 MHz with 2 ns rise/fall times. For sustained 200 MHz operation, derating to 3.0 V VCC and controlled 50 pF load (per Table 9) is recommended.
