Product details
Overview
74ALVT16241DL,112 from NXP Semiconductors (formerly Philips) is a 16-bit 3-state BiCMOS buffer/driver designed for bus interface applications at 2.5 V or 3.3 V VCC, with 5 V-tolerant I/O. It features four independent output-enable inputs (1OE–4OE), each controlling four outputs, and delivers ±64 mA/−32 mA drive capability. It supports live insertion/extraction and includes bus-hold on data inputs to eliminate external pull-ups.
For engineers reviewing the 74ALVT16241DL,112 datasheet, 74ALVT16241DL,112 pinout, 74ALVT16241DL,112 application, or 74ALVT16241DL,112 equivalent, this device is critical for high-speed 3.3 V/2.5 V system bus buffering where 5 V signal compatibility, low propagation delay (as low as 0.5 ns typ.), and robust ESD protection (>2000 V HBM) are required.
Technical Context
The 74ALVT16241DL,112 implements TTL-compatible input and output switching levels while operating from a 2.5 V or 3.3 V supply, enabling seamless interfacing between mixed-voltage domains. Its four independent 3-state control inputs allow granular bus segment management without affecting other channels.
Each of the 16 outputs exhibits active-drive capability up to +64 mA (sourcing) and −32 mA (sinking) under specified conditions, with power-up 3-state behavior ensuring outputs remain high-impedance during power ramp-up. Bus-hold circuitry maintains valid logic states on unused data inputs without external components.

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 in TSSOP48; identical 2.5/3.3 V operation and 5 V I/O, but higher IOL = −64 mA (same), lower tPLH = 1.4 ns (typ.) at 3.3 V | Same bus-hold and live-insertion support; slightly faster propagation but no bus-hold current spec published | Select when sub-1.5 ns propagation is required and TI supply chain preference applies |
| 74LVT16244ADL,118 | NXP part in same SSOP48; non-inverting (vs. inverting in 74ALVT16241), identical VCC range, 5 V I/O, and bus-hold, but lower drive (−32 mA only) | Used where unidirectional non-inverting buffering suffices; lacks independent OE per 4-bit group (shared OE) | Select for cost-sensitive designs needing simpler enable architecture and reduced drive capability |
Compared with SN74ALVTH16241DGGR and 74LVT16244ADL,118, the 74ALVT16241DL,112 offers unique per-group OE control and balanced ±64 mA/−32 mA drive-critical for bidirectional bus arbitration and mixed-sink/source load matching.

FAQ
What is the maximum recommended supply voltage for the 74ALVT16241DL,112?
The absolute maximum supply voltage (VCC) for the 74ALVT16241DL,112 is +4.6 V, but the recommended operating range is 2.3 V to 2.7 V at 2.5 V nominal or 3.0 V to 3.6 V at 3.3 V nominal. Exceeding 3.6 V in normal operation risks violating recommended conditions and may impact long-term reliability. The 74ALVT16241DL,112 is not rated for continuous 5 V VCC operation.
Does the 74ALVT16241DL,112 support true bidirectional data flow?
No-the 74ALVT16241DL,112 is a unidirectional buffer: data flows only from A-inputs to Y-outputs. It does not contain internal direction control or transceiver functionality. Bidirectional operation requires external control logic and separate transmit/receive paths. The 74ALVT16241DL,112 is optimized for driving address, control, or data buses in one direction with high sink/source capability.
How does bus-hold functionality work on the 74ALVT16241DL,112 data inputs?
The 74ALVT16241DL,112 integrates weak feedback resistors (~100 kΩ equivalent) on all data inputs (1A0–4A3), providing ±70–140 µA overdrive current to hold the last valid logic state when inputs float. This eliminates external pull-up/pull-down resistors and prevents undefined states during power-up, standby, or disconnected operation. Bus-hold is inactive on OE pins.
Can the 74ALVT16241DL,112 be used with a 5 V VCC supply?
No-the 74ALVT16241DL,112 is specified only for 2.5 V or 3.3 V VCC operation. While its I/O pins tolerate up to 5.5 V, applying 5 V to VCC exceeds the absolute maximum rating of +4.6 V and will damage the device. For 5 V systems, use dedicated 5 V logic families such as 74ACT or 74AS series instead.
What is the thermal resistance (θJA) of the 74ALVT16241DL,112 in SSOP48 package?
The datasheet for the 74ALVT16241DL,112 does not specify θJA (junction-to-ambient thermal resistance). As an SSOP48 package (SOT370-1) with moderate power dissipation (<100 µA ICC when disabled), thermal performance is typically sufficient for standard PCB layouts with minimal copper pour. For high-duty-cycle or high-temperature applications, derating and board-level thermal analysis using JEDEC JESD51-2 guidelines is recommended. The 74ALVT16241DL,112 has no thermal pad or exposed die attach.
