Product details
Overview
74ALVT16241DGG,512 from NXP Semiconductors (formerly Philips) is a 16-bit 3-state buffer/driver IC designed for high-speed bus interfacing in mixed-voltage systems. It operates at 2.5 V or 3.3 V VCC with 5 V-tolerant I/O, features four independent output-enable inputs (1OE–4OE), and delivers ±64 mA/−32 mA drive capability. It is used in backplane and motherboard data bus drivers where level translation and bus hold functionality are required.
For engineers reviewing the 74ALVT16241DGG,512 datasheet, 74ALVT16241DGG,512 pinout, 74ALVT16241DGG,512 application, or 74ALVT16241DGG,512 equivalent, key selection considerations include its 48-pin TSSOP package, 2.5/3.3 V supply compatibility, 5 V I/O tolerance, bus hold inputs eliminating external pull-ups, and sub-3 ns propagation delay at 3.3 V.
Technical Context
The 74ALVT16241DGG,512 implements a BiCMOS architecture enabling TTL-compatible input switching levels and 5 V I/O robustness while operating from low-voltage supplies. Its four independent 3-state control inputs allow granular enable/disable of four 4-bit output groups, supporting segmented bus management.
Each of the 16 outputs exhibits bus hold circuitry on data inputs, providing active input stabilization without external resistors. The device supports live insertion/extraction and power-up 3-state behavior, ensuring safe hot-swap operation and predictable initial state during power ramp.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 2.5 V ± 0.2 V or 3.3 V ± 0.3 V - enables dual-voltage system integration with stable logic thresholds |
| I/O Voltage Range | 0 V to 5.5 V - allows direct interface to legacy 5 V buses without level shifters |
| tPLH / tPHL | 1.6 ns typ @ 3.3 V - ensures sub-nanosecond timing margin for 200+ MHz bus operation |
| Output Drive | +64 mA sink / −32 mA source - drives heavy capacitive loads (e.g., >50 pF) with clean edges |
| Bus Hold Current | ±75 µA min @ 3 V - actively holds unused inputs at valid logic levels, removing need for 10 kΩ pull-ups |
| ICC (disabled) | 70 µA max @ 3.3 V - ultra-low quiescent current during bus isolation |

Pinout & Package
TSSOP48 package (SOT362-1): plastic thin shrink small outline, 48 leads, 6.1 mm body width, 0.5 mm pitch, lead-free compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 25, 48, 24 | 1OE, 2OE, 3OE, 4OE | Active-low group enable controls - each enables four corresponding Y outputs independently |
| 2–6, 8–12, 13–17, 19–23 | 1Y0–1Y3, 2Y0–2Y3, 3Y0–3Y3, 4Y0–4Y3 | 16 buffered 3-state outputs - high-impedance when OE asserted, driven otherwise |
| 43–47, 37–41, 32–36, 26–30 | 1A0–1A3, 2A0–2A3, 3A0–3A3, 4A0–4A3 | 16 data inputs with bus hold - retain last valid logic state without external biasing |
| 4, 7, 10, 15, 18, 21, 28, 31, 34, 39, 42, 45 | GND / VCC | Dual power/ground distribution - 6× GND and 6× VCC pins minimize ground bounce and supply noise |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ALVTH16241DGGR | TI part; same 48-pin TSSOP, 2.3–3.6 V operation, but higher IOH (−64 mA) and lower tPLH (1.3 ns typ @ 3.3 V) | Optimized for ultra-low skew in high-speed memory interfaces; lacks bus hold inputs | Select when maximum speed and drive strength are critical and external pull-ups are acceptable |
| 74LVT16244ADGG,118 | NXP part; identical pinout and bus hold, but non-inverting (vs. inverting in 74ALVT16241); 3.3 V only, no 2.5 V support | Suitable for unidirectional data paths requiring polarity preservation; not usable in 2.5 V domains | Select when signal inversion must be avoided and system runs exclusively at 3.3 V |
Compared with SN74ALVTH16241DGGR and 74LVT16244ADGG,118, the 74ALVT16241DGG,512 uniquely combines 2.5 V/3.3 V dual-supply operation, integrated bus hold, and 5 V I/O tolerance - making it the only option for cost-sensitive, mixed-voltage industrial backplanes requiring zero external bias components.

FAQ
What supply voltages does the 74ALVT16241DGG,512 support?
The 74ALVT16241DGG,512 supports two nominal supply voltages: 2.5 V ± 0.2 V and 3.3 V ± 0.3 V. It is not rated for 5 V VCC operation. Its I/O pins tolerate up to 5.5 V regardless of VCC, enabling safe interfacing with 5 V buses while powered from lower voltages. This dual-supply capability is explicitly defined in Table 7 of the datasheet under Recommended Operating Conditions.
Does the 74ALVT16241DGG,512 have bus hold functionality, and how does it work?
Yes, the 74ALVT16241DGG,512 includes bus hold circuitry on all 16 data inputs (1A0–4A3). As specified in Table 8, it provides ±75 µA minimum hold current at 3 V, actively maintaining the last valid logic state when inputs float. This eliminates the need for external 10 kΩ pull-up or pull-down resistors, reducing component count and PCB space. The feature is inherent to the silicon design and requires no configuration.
What is the propagation delay of the 74ALVT16241DGG,512 at 3.3 V operation?
At VCC = 3.3 V ± 0.3 V and CL = 50 pF, the 74ALVT16241DGG,512 has a typical propagation delay (tPLH/tPHL) of 1.6 ns, with a maximum of 2.3 ns. These values are measured from input (nAx) to corresponding output (nYx) under standard test conditions per Figure 4 and Table 9. The low delay enables reliable operation in systems with clock periods down to 5 ns.
Is the 74ALVT16241DGG,512 pin-compatible with other 48-pin TSSOP logic buffers?
The 74ALVT16241DGG,512 uses the SOT362-1 (TSSOP48) package with 0.5 mm pitch and 6.1 mm body width. While physically compatible with other 48-pin TSSOP devices, functional pin compatibility is limited to identical members of the 74ALVT16241 family (e.g., 74ALVT16241DGG,118). It is not pin-compatible with non-inverting variants like 74LVT16244 or TI's SN74ALVTH16241 due to differing OE and I/O assignments.
What ESD protection level does the 74ALVT16241DGG,512 provide?
The 74ALVT16241DGG,512 meets MIL-STD-883 Method 3015 with >2000 V human-body-model (HBM) ESD rating and exceeds 200 V machine-model (MM) rating. These values are confirmed in Section 2 (Features) and Table 6 (Limiting Values) of the datasheet. Latch-up protection exceeds 500 mA per JESD78, ensuring robustness in handling transient overstress events during assembly and field use.
