Product details
Overview
74ALVT16240DGG,112 from NXP Semiconductors (formerly Philips) is a 16-bit inverting 3-state buffer/driver designed for bus interface applications with dual supply compatibility at 2.5 V or 3.3 V and 5 V I/O tolerance. It features four independent output-enable inputs (1OE–4OE), each controlling four outputs, and delivers ±64 mA/−32 mA drive capability. Used in high-speed digital backplanes and memory address/data buses.
For engineers reviewing the 74ALVT16240DGG,112 datasheet, 74ALVT16240DGG,112 pinout, 74ALVT16240DGG,112 application, or 74ALVT16240DGG,112 equivalent, this device supports live insertion, includes bus-hold inputs to eliminate external pull-ups, and provides sub-3 ns propagation delay at 3.3 V - critical for timing-critical 5 V-tolerant system interconnects.
Technical Context
The 74ALVT16240DGG,112 implements BiCMOS logic to achieve TTL-compatible input thresholds and 5 V-tolerant outputs while operating from 2.5 V or 3.3 V supplies. Its four-group 3-state architecture enables selective bus segment control without contention.
Each output group (Y0–Y3 per enable) inverts its corresponding input (A0–A3), and all outputs enter high-impedance state when their respective OE is HIGH. Power-up 3-state behavior prevents bus glitches during power ramp-up.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 2.5 V ±0.2 V or 3.3 V ±0.3 V - enables direct integration into mixed-voltage systems without level shifters |
| I/O Voltage Tolerance | Up to 5.5 V - allows safe interfacing with legacy 5 V logic without damage or clamping current overload |
| tPLH / tPHL | 0.5–3.0 ns (typ/max at 3.3 V, CL = 50 pF) - supports >300 MHz bus toggle rates in point-to-point configurations |
| Output Drive | +64 mA sink / −32 mA source - sufficient to drive 50 Ω transmission lines or multiple TTL loads |
| Bus-Hold Current | ±75 µA to ±140 µA (at VCC = 3 V) - actively holds unused inputs at valid logic levels, removing need for external bias resistors |
| Input Capacitance | 3 pF (on OE pins) - minimizes loading on control signals and preserves signal integrity in dense routing |
| ICC (disabled) | 60 µA max at 3.3 V - ultra-low quiescent current during bus isolation, reducing system standby power |

| VCC (Pins 7, 18, 31, 42) | Supply voltage | Four dedicated VCC pins reduce IR drop and improve noise immunity across wide bus |
| GND (Pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight GND pins provide low-inductance return paths for all output groups and minimize ground bounce |

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 |
|---|---|---|---|
| SN74ALVTH16240GR | TI part; same 16-bit inverting 3-state function, 2.3–3.6 V VCC, 5 V tolerant, but uses different pinout (Gang OE vs individual OE) and lacks bus-hold | Requires external pull-ups on unused inputs; gang enable limits per-group bus arbitration | Select if system uses centralized enable control and external biasing is acceptable |
| 74LVT16240ADGG,112 | NXP variant with identical pinout and bus-hold, but rated only for 3.3 V operation (not 2.5 V); slightly higher ICC and reduced drive (−24 mA) | Not suitable for 2.5 V systems; lower drive insufficient for heavy capacitive loads or long traces | Select only for 3.3 V-only designs where cost is prioritized over 2.5 V flexibility and full drive strength |
Compared with SN74ALVTH16240GR and 74LVT16240ADGG,112, the 74ALVT16240DGG,112 uniquely combines individual 4-bit OE control, integrated bus-hold, and dual 2.5 V/3.3 V supply support - making it optimal for flexible, high-reliability bus segmentation in mixed-voltage embedded systems.
