Product details
Overview
74LVC16241ADL,112 from Nexperia is a 16-bit non-inverting buffer/line driver with 3-state outputs, 5 V tolerant I/O, and Schmitt-trigger inputs for noise immunity. It operates from 1.2 V to 3.6 V supply, supports mixed-voltage interfacing (3.3 V logic driving 5 V buses), and is rated for -40 °C to +125 °C. Used in high-density data bus isolation and level translation in industrial control backplanes.
For engineers reviewing the 74LVC16241ADL,112 datasheet, 74LVC16241ADL,112 pinout, 74LVC16241ADL,112 application, or 74LVC16241ADL,112 equivalent, key selection criteria include 5 V tolerance on all I/O pins, TSSOP48 package thermal performance, propagation delay ≤5.5 ns at 3.3 V, 3-state enable timing asymmetry between active-low (1OE/4OE) and active-high (2OE/3OE) controls, and compliance with JEDEC JESD8-7A/5A/C standards.
Technical Context
This device implements four independent 4-bit non-inverting buffers, each with dedicated output-enable control (1OE–4OE). Two enable types are present: 1OE and 4OE are active-low; 2OE and 3OE are active-high - enabling flexible bus arbitration schemes without external inverters. All inputs feature Schmitt-trigger thresholds, ensuring robust operation with slow-rising signals up to 20 ns/V at 1.65 V.
The 48-pin TSSOP package integrates eight ground and four VCC pins to minimize simultaneous switching noise. Input leakage remains ≤±0.1 μA at 3.6 V supply with 5.5 V applied to pins, and OFF-state output current is ≤±0.1 μA when VCC = 0 V - supporting true power-down isolation in hot-swap systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.2 V to 3.6 V - enables direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic families |
| I/O Voltage Tolerance | 0 V to 5.5 V - allows safe connection to 5 V buses while powered from 3.3 V or lower supplies |
| Propagation Delay (tpd) | ≤4.4 ns at VCC = 3.3 V - ensures sub-5 ns timing margin for 100 MHz bus clocking |
| Enable/Disable Time (ten/tdis) | ≤5.5 ns at VCC = 3.3 V - supports fast bus turnaround in time-multiplexed architectures |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 24 (1OE, 4OE) | Active-low output enable | Drives corresponding Y-group into high-impedance when LOW; no external pull-up required |
| 48, 25 (2OE, 3OE) | Active-high output enable | Enables Y-group when HIGH; eliminates need for inverter in synchronous enable paths |
| 2–3, 5–6, 8–9, 11–12, 13–14, 16–17, 19–20, 22–23 | Data outputs (1Y0–4Y3) | 16 total 3-state outputs; each group of 4 shares one OE signal |

| 4, 10, 15, 21, 28, 34, 39, 45 | GND | Eight ground pins reduce ground bounce and improve signal integrity in high-speed switching |
| 7, 18, 31, 42 | VCC | Four supply pins distribute current and lower effective series inductance for stable core voltage |
Key Features
| Feature | Design Value |
|---|---|
| MULTIBYTE flow-through pinout | Input A0–A3 and output Y0–Y3 aligned per byte group - simplifies PCB routing and reduces trace crossovers |

Applications
| Industrial Backplane Interface | Memory Expansion Subsystem |
|---|---|
Use Scenario: Isolating CPU address/data bus from peripheral modules in modular PLC racks with varying supply domains. IC Role / Device Role / Timing Role: Non-inverting 16-bit buffer with independent 4-bit group enables, providing bidirectional bus separation and slew-rate controlled signal integrity. Use Value: 5 V tolerance prevents latch-up when legacy 5 V peripherals connect to 3.3 V controllers; Schmitt inputs reject noise from long backplane traces. | Use Scenario: Driving parallel SRAM or Flash memory data/address lines in embedded instrumentation with strict timing budgets. IC Role / Device Role / Timing Role: Low-skew, low-delay line driver with matched propagation paths across all 16 bits. Use Value: 4.4 ns max tpd at 3.3 V enables reliable 100 MHz memory access; 15 pF CPD allows precise dynamic power modeling. |
| Automated Test Equipment (ATE) Fixture | Programmable Logic I/O Expansion |
Use Scenario: Level-shifting and buffering between FPGA I/O banks (1.2 V/1.8 V) and DUT test points requiring 5 V TTL-compatible signals. IC Role / Device Role / Timing Role: 3-state driver with dual-polarity OE inputs enables synchronized test vector loading and response capture. Use Value: Asymmetric OE polarity (1OE/4OE active-low, 2OE/3OE active-high) matches common ATE pattern generator signal conventions. | Use Scenario: Expanding I/O count of CPLD/FPGA designs where native pins are insufficient for sensor/actuator interfacing. IC Role / Device Role / Timing Role: Parallel input/output buffer with independent group enables for dynamic resource allocation. Use Value: Four independent 4-bit sections allow partial reconfiguration without disturbing other I/O groups; low ICC (≤80 μA) minimizes quiescent power overhead. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit non-inverting buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC16244ADGGR | Inverting output logic; identical pinout, supply range, and 5 V tolerance | Requires logic inversion in system design; unsuitable where signal polarity must be preserved | Select only if system-level inversion is acceptable or already compensated |
| 74ALVC16244DGG,118 | Higher drive strength (±24 mA vs. ±12 mA at 3.3 V); faster tpd (≤3.2 ns); same TSSOP48 package | Better suited for longer traces or heavier capacitive loads (>50 pF); higher ICC (≤100 μA) | Choose when speed or drive capability outweighs static power sensitivity |
Compared with SN74LVC16244ADGGR, the 74LVC16241ADL,112 preserves signal polarity critical for address/data integrity; versus 74ALVC16244DGG,118, it trades 1.2 ns speed and 12 mA drive for 20 μA lower quiescent current - favoring battery-powered or thermally constrained systems.

FAQ
What is the maximum allowable input voltage when VCC = 0 V?
When VCC = 0 V, inputs may be safely driven up to 5.5 V due to integrated input clamping diodes and power-off leakage current ≤±10 μA. This enables hot-insertion into live backplanes without damaging the device or pulling down upstream logic rails.
Can 1OE and 2OE be used simultaneously to control the same output group?
No - 1OE controls outputs 1Y0–1Y3, 2OE controls 2Y0–2Y3, 3OE controls 3Y0–3Y3, and 4OE controls 4Y0–4Y3. Each OE input is hardwired to its respective 4-bit output group; cross-driving violates functional design and may cause undefined output states.
Does the device support partial power-down with some sections active and others disabled?
Yes - each 4-bit section (1A/1Y, 2A/2Y, 3A/3Y, 4A/4Y) operates independently. With VCC applied, individual groups can be enabled/disabled via their dedicated OE inputs while others remain in high-impedance, enabling dynamic bus segmentation without global reset.
What is the recommended PCB layout practice for minimizing ground bounce?
Use all eight GND pins (pins 4, 10, 15, 21, 28, 34, 39, 45) with dedicated vias to a solid ground plane. Place 100 nF ceramic decoupling capacitors within 3 mm of each VCC pin (7, 18, 31, 42), and route power/ground traces symmetrically to balance return current paths.
