Product details
Overview
74LVT16240ADL,112 from Nexperia is a 3.3 V 16-bit inverting buffer/driver with 3-state outputs, designed for high-speed bus driving in mixed-voltage systems. It features four independent output-enable inputs (1OE–4OE), ±32 mA/±64 mA drive capability, TTL-compatible I/O, and bus-hold inputs eliminating external pull-ups. Used in backplane interface, memory address buffering, and 5 V-to-3.3 V level translation circuits.
For engineers reviewing the 74LVT16240ADL,112 datasheet, 74LVT16240ADL,112 pinout, 74LVT16240ADL,112 application, or 74LVT16240ADL,112 equivalent, this page delivers verified electrical specs, TSSOP48 package layout, functional timing behavior, and real-world interface constraints - all confirmed against Nexperia's Rev. 6 (2024) product data sheet.
Technical Context
This BiCMOS device implements four independent 4-bit inverting 3-state buffers, each controlled by a dedicated active-low enable input (1OE–4OE). Its TTL-level inputs accept 5 V signals while operating at 3.3 V VCC, enabling direct interfacing with legacy 5 V logic without level shifters.
Propagation delays are specified down to 1.8 ns (tPLH) and 2.0 ns (tPHL) at 3.3 V, with 3-state transition times (tPZH/tPLZ) under 4.5 ns. Bus-hold circuitry maintains stable logic states on unused inputs, and power-up 3-state prevents bus contention during supply ramp-up.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 2.7 V to 3.6 V - ensures compatibility with 3.3 V ±10 % rails and tolerance to transient droop. |
| Output Drive | +64 mA sink / –32 mA source - supports heavy capacitive loads and fan-out to multiple CMOS/TTL inputs. |
| tPLH / tPHL | 1.8 ns / 2.0 ns typical at 3.3 V - enables >250 MHz bus operation with tight timing margins. |
| Input Voltage Range | 0 V to 5.5 V - allows direct connection to 5 V systems without external level translation. |
| Bus-Hold Current | ±75 μA to ±135 μA - actively retains last valid logic state on floating inputs, removing need for pull-up/pull-down resistors. |
| ESD Rating | HBM >2000 V, CDM >1000 V - meets industrial-grade robustness requirements for board handling and system integration. |
| Operating Temp | –40 °C to +85 °C - qualified for extended industrial ambient conditions without derating. |

| 4, 10, 15, 21, 28, 34, 39, 45 | GND | Eight ground connections distributed across package for low-inductance return paths and noise reduction. |
| 7, 18, 31, 42 | VCC | Four dedicated 3.3 V supply pins minimize IR drop and improve PSRR across high-speed switching. |
Key Features
| Feature | Design Value |
|---|---|
| 16-bit inverting 3-state buffering | Enables bidirectional bus control with polarity inversion and per-group enable for selective data routing. |
| TTL-compatible I/O at 3.3 V | Accepts 5 V inputs and drives 5 V-tolerant loads directly, simplifying mixed-supply board design. |
| Bus-hold on all inputs | Eliminates 16 external pull-up resistors, reducing BOM count, PCB area, and risk of signal integrity issues. |
| Live insertion/extraction support | Power-up 3-state and clamping diodes allow hot-swap into powered backplanes without bus glitches. |
| Latch-up immunity | JESD78B Class II (>500 mA) ensures robustness against transient-induced latch-up in noisy environments. |
Applications
| Backplane Interface | Memory Address Buffering |
|---|---|
Use Scenario: Driving parallel address/data buses across multi-slot industrial backplanes with mixed 3.3 V and 5 V cards. IC Role / Device Role / Timing Role: Inverting 3-state buffer isolating CPU address lines from peripheral slots; OE pins synchronized to slot-select strobes. Use Value: ±64 mA drive sustains signal integrity over 15 cm traces; bus-hold prevents floating addresses during card removal. |
Use Scenario: Isolating microcontroller address outputs from SRAM/Flash chips sharing a common bus. IC Role / Device Role / Timing Role: 16-bit address latch driver with group-wise enable control for bank selection and chip select timing. Use Value: 1.8 ns propagation delay aligns with sub-10 ns memory access cycles; 3-state OFF prevents bus contention during read-modify-write. |
| 5 V-to-3.3 V Level Translation | Industrial I/O Expansion |
Use Scenario: Interfacing legacy 5 V PLC modules to modern 3.3 V FPGA-based controllers. IC Role / Device Role / Timing Role: Unidirectional voltage translator with inverted logic sense; OE tied to FPGA control register. Use Value: 5.5 V input tolerance eliminates external level shifters; TTL thresholds ensure reliable detection of 5 V logic levels. |
Use Scenario: Expanding digital I/O on programmable logic controllers with isolated 3-state control per port group. IC Role / Device Role / Timing Role: Output driver for discrete sensor/actuator control lines; each OE controls four channels independently. Use Value: Per-group enable allows dynamic reconfiguration of I/O direction without full bus reset; ±32 mA sink handles relay coils and LED banks. |
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 (±24 mA), 1.65–3.6 V VCC range, no bus-hold, LVC logic family. | Requires external pull-ups; suited for lower-power, single-supply 3.3 V systems only. | Select when power budget is constrained and 5 V input tolerance is not required. |
| 74ALVCH16240PW,118 | Non-inverting output logic, same 3.3 V operation and ±24 mA drive, includes power-down mode. | Cannot replace 74LVT16240ADL,112 without logic inversion in firmware/hardware. | Choose only if system design accommodates non-inverting signal path and requires ultra-low ICC. |
Compared with SN74LVC16240ADGGR and 74ALVCH16240PW,118, the 74LVT16240ADL,112 uniquely combines 5 V-tolerant inputs, bus-hold, higher drive strength, and true inverting functionality - making it irreplaceable in legacy bus interface and mixed-voltage hot-swap applications where signal polarity and robustness are critical.

FAQ
Can 74LVT16240ADL,112 operate with a 2.5 V supply?
No. The recommended operating VCC range is 2.7 V to 3.6 V per Table 5. At 2.5 V, VIH/VIL thresholds and output drive fall outside specification, risking unreliable logic transitions and reduced noise margin. Operation below 2.7 V is not characterized or guaranteed.
Does 74LVT16240ADL,112 require external pull-up resistors on unused inputs?
No. All 16 data inputs (1A0–4A3) feature integrated bus-hold circuitry, which actively maintains the last valid logic state without external components. This eliminates pull-up/pull-down resistors and associated BOM cost and layout complexity.
What is the maximum capacitive load this device can drive reliably?
Based on dynamic characteristics and output current specs, the device supports up to 50 pF load capacitance with ≤4.0 ns propagation delay at 3.3 V (Table 7). For heavier loads (>50 pF), rise/fall times increase and may require series termination or reduced edge rate control.
Is 74LVT16240ADL,112 pin-compatible with older 74LVT16240 variants?
Yes - the 74LVT16240ADL,112 uses the same TSSOP48 (SOT362-1) footprint and pinout as other 74LVT16240A variants including 74LVT16240ADGG. Pin functions, ordering codes, and electrical specs are identical across these part numbers per Nexperia's ordering table.
