Product details
Overview
74LVT16240ADGG,512 from Nexperia is a 3.3 V, 16-bit inverting 3-state buffer/driver in TSSOP48 package, designed for high-speed bus driving with ±32 mA/±64 mA output drive capability, TTL-compatible I/O, and bus-hold inputs eliminating external pull-ups. It operates across -40 °C to +85 °C and supports mixed-voltage interfacing (3.3 V core, 5 V bus).
For engineers reviewing the 74LVT16240ADGG,512 datasheet, 74LVT16240ADGG,512 pinout, 74LVT16240ADGG,512 application, or 74LVT16240ADGG,512 equivalent, key selection criteria include output enable granularity (four independent OE pins), propagation delay ≤3.2 ns at 3.3 V, bus-hold current specifications, and compatibility with 5 V-tolerant systems without level shifters.
Technical Context
The device implements four independent 4-bit inverting buffer sections, each controlled by a dedicated active-low output enable (1OE–4OE). Each section drives four outputs (e.g., 1Y0–1Y3) from corresponding inputs (1A0–1A3), with true inversion logic and high-impedance OFF-state when OE is HIGH.
Its BiCMOS architecture enables TTL-level input thresholds (VIH ≥2.0 V, VIL ≤0.8 V) while operating from a 3.3 V supply, and supports live insertion/extraction via power-up 3-state behavior and robust ESD protection (HBM >2000 V, CDM >1000 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| 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 | +64 mA sink / –32 mA source - Supports heavy capacitive bus loads and fan-out to multiple CMOS/TTL inputs. |
| tPLH/tPHL | 0.5 ns to 3.2 ns (typ. 1.8/2.0 ns @3.3 V) - Enables sub-4 ns signal propagation for high-speed data buses. |
| Bus-Hold Current | IBHL = 75–135 μA, IBHH = –75 to –135 μA - Maintains valid logic states on unused inputs without external resistors. |
| IOFF Leakage | ±100 μA max @VCC = 0 V - Prevents backfeeding and ensures safe power-down isolation in hot-swap scenarios. |
| ESD Rating | HBM >2000 V, CDM >1000 V - Meets industrial-grade robustness requirements per JS-001/JS-002. |
| Operating Temp | –40 °C to +85 °C - Qualified for extended industrial temperature range without derating. |

| VCC (Pins 7,18,31,42) | Supply voltage | Four VCC pins reduce supply impedance and stabilize core voltage under dynamic load transitions. |
Key Features
| Feature | Design Value |
|---|---|
| Independent 4×4-bit OE control | Enables selective activation of bus segments-reducing contention, crosstalk, and dynamic power in multi-drop systems. |
| Bus-hold inputs | Eliminates need for 10 kΩ external pull-up/pull-down resistors on unused inputs, saving PCB area and BOM cost. |
| 5 V-tolerant I/O | Accepts 0–5.5 V input signals and drives 5 V buses without level shifters-simplifies mixed-voltage board design. |

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 | Lower drive (+32 mA/–32 mA), 1.65–3.6 V VCC range, no bus-hold inputs | Requires external pull-ups on unused inputs; suited for lower-power, single-supply 3.3 V systems only | Select when bus-hold is unnecessary and total system power budget is constrained below 100 mW. |
| 74ALVT16240PCB | Higher speed (tPLH/tPHL ≤2.5 ns), 2.5–3.3 V VCC, no 5 V tolerance, higher ICC (0.25 mA typ) | Not compatible with 5 V buses; requires strict 2.5–3.3 V rail regulation and additional level-shifting circuitry | Select only when maximum speed is prioritized over voltage flexibility and industrial temperature range. |
Compared with SN74LVC16240ADGGR and 74ALVT16240PCB, the 74LVT16240ADGG,512 uniquely combines 5 V-tolerant I/O, bus-hold inputs, and ±64 mA drive in an industrial-temperature TSSOP48 package-making it optimal for mixed-voltage, high-reliability bus interface where external components must be minimized.

FAQ
Is the 74LVT16240ADGG,512 compatible with 5 V logic systems?
Yes. Its inputs accept 0–5.5 V signals and outputs drive 5 V buses directly, with VIH ≥2.0 V and VIL ≤0.8 V thresholds matching TTL levels. No external level shifters are needed when interfacing with 5 V microcontrollers, FPGAs, or legacy peripherals.
What is the function of the bus-hold feature?
The bus-hold circuit maintains the last valid logic state on unused inputs using internal feedback, drawing 75–135 μA (LOW) or –75 to –135 μA (HIGH). This eliminates external pull-up/pull-down resistors, reducing BOM count and PCB space while preventing floating-input-induced noise coupling.
How does the four-output-enable architecture improve system design?
Each OE pin (1OE–4OE) controls four outputs independently, allowing segmented bus enable/disable. This reduces simultaneous switching noise, enables selective power gating of bus sections, and supports hot-plug protocols by isolating inactive slots-critical in modular industrial and test equipment.
Does the device support live insertion and extraction?
Yes. The power-up 3-state feature holds all outputs in high-impedance until VCC stabilizes, and the BiCMOS structure with robust ESD/latch-up protection (HBM >2000 V, JESD78B Class II >500 mA) enables safe insertion/extraction in powered-backplane systems without risk of bus conflict or damage.
