Product details

Overview

74ALVT16240DL,112 from NXP Semiconductors (formerly Philips) is a 16-bit inverting 3-state buffer/driver IC designed for high-speed bus interface applications with dual V_CC support at 2.5 V or 3.3 V and full 5 V I/O tolerance. It features four independent output-enable inputs (1OE–4OE), each controlling four buffered outputs, and delivers ±64 mA drive capability on HIGH/LOW states. Used in backplane and motherboard data routing where level translation and bus contention control are required.

For engineers reviewing the 74ALVT16240DL,112 datasheet, 74ALVT16240DL,112 pinout, 74ALVT16240DL,112 application, or 74ALVT16240DL,112 equivalent, this device serves as a high-drive, low-propagation-delay bus driver supporting mixed-voltage system interconnects - particularly where live insertion, bus hold, and power-up 3-state behavior are critical to system robustness.

Technical Context

The 74ALVT16240DL,112 implements a BiCMOS architecture enabling fast switching (typical t_PLH/t_PHL = 1.7 ns at 3.3 V, CL = 50 pF) while maintaining TTL-compatible input thresholds and 5 V-tolerant I/O. Its four grouped 3-state controls allow selective activation of 4-bit output segments, reducing bus loading during partial enable scenarios.

Each input incorporates bus-hold circuitry (IHOLD ≥ 75 µA at 3 V) eliminating external pull-ups on unused data lines, and the device guarantees power-up 3-state behavior to prevent bus contention during power sequencing. Absolute maximum ratings include 7.0 V input/output voltage tolerance and 128 mA sink current capability.

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 in 48-pin TSSOP (SOT362-1); identical 2.5/3.3 V operation but lower max sink current (−32 mA vs −64 mA)	Lower drive limits suitability for lighter loads; same bus-hold and 5 V tolerance	Select when board space favors TSSOP and load capacitance <40 pF
74LVT16240ADL,118	NXP variant with identical pinout and function but LVT (not ALVT) process - higher ICC (up to 0.5 mA disabled vs 0.1 mA) and slower t_PLH (4.5 ns max at 3.3 V)	Higher static power and reduced speed margin; otherwise drop-in compatible	Select only if ALVT-grade performance is not required and cost is primary constraint

Compared with SN74ALVTH16240GR and 74LVT16240ADL,118, the 74ALVT16240DL,112 offers superior drive strength and faster propagation, making it optimal for high-speed, high-load bus interfaces - whereas alternatives trade performance for cost or package size without matching its BiCMOS-level speed-power balance.

FAQ

What is the maximum output current rating for 74ALVT16240DL,112?

The 74ALVT16240DL,112 supports −64 mA sink current and +64 mA source current per output under recommended operating conditions. This rating applies at V_CC = 3.3 V with duty cycle ≤50 % and f ≥1 kHz, enabling reliable driving of heavy capacitive loads or multiple TTL inputs without external buffering. The 74ALVT16240DL,112 maintains this drive strength across its full −40 °C to +85 °C operating range.

Does 74ALVT16240DL,112 support live insertion?

Yes, the 74ALVT16240DL,112 supports live insertion due to three key features: guaranteed power-up 3-state behavior, integrated bus-hold on all data inputs, and I/O clamp current compliance (±50 mA). These ensure no bus contention or undefined states occur during hot-plug events. The 74ALVT16240DL,112 meets MIL-STD-883 ESD requirements (>2000 V), further validating its suitability for field-replaceable modules.

What package type is used for 74ALVT16240DL,112?

The 74ALVT16240DL,112 uses the SSOP48 (shrink small outline package) with 48 leads, body width 7.5 mm, and JEDEC standard outline SOT370-1. It is distinct from the TSSOP48 variant (74ALVT16240DGG), featuring wider lead pitch and enhanced thermal dissipation. The 74ALVT16240DL,112 package is RoHS-compliant and qualified for industrial temperature operation (−40 °C to +85 °C).

How does bus-hold functionality work on 74ALVT16240DL,112?

The 74ALVT16240DL,112 integrates bus-hold circuitry on all data input pins (A0–A15), providing ±75 µA minimum overdrive current at 3 V to maintain the last-valid logic state when inputs float. This eliminates the need for external 10–100 kΩ pull-up/down resistors. The 74ALVT16240DL,112 bus-hold remains active across the full V_CC range (2.3–3.6 V) and ambient temperature span (−40 °C to +85 °C).

Can 74ALVT16240DL,112 operate with a 2.5 V supply and interface to 5 V logic?

Yes, the 74ALVT16240DL,112 is explicitly designed for 2.5 V or 3.3 V V_CC operation while maintaining full 5 V I/O tolerance - inputs and outputs safely accept 0–5.5 V signals regardless of supply voltage. This allows seamless interfacing between 2.5 V FPGAs and legacy 5 V peripherals. The 74ALVT16240DL,112 achieves this via internal level-shifting structures and robust input clamp diodes rated to ±50 mA.
