Product details
Overview
74LVCH16541ADL,112 from Nexperia is a 16-bit non-inverting 3-state buffer/line driver with dual independent output-enable control (1OEn/2OEn), bus-hold inputs, 5 V-tolerant I/O, and operation from 1.2 V to 3.6 V supply. It supports mixed-voltage interfacing between 3.3 V and 5 V logic domains in high-density data buses, with guaranteed operation from –40 °C to +125 °C.
For engineers reviewing the 74LVCH16541ADL,112 datasheet, 74LVCH16541ADL,112 pinout, 74LVCH16541ADL,112 application, or 74LVCH16541ADL,112 equivalent, this device delivers deterministic propagation delay (≤5.5 ns at 3.3 V), low-noise TSSOP48 packaging with multiple GND/VCC pins, and bus-hold functionality eliminating external pull-ups on unused inputs.
Technical Context
The 74LVCH16541ADL,112 implements two independent 8-bit buffered channels (Group 1: A0–A7 → Y0–Y7; Group 2: A0–A7 → Y0–Y7), each with separate active-low output enables (1OE1/1OE2 and 2OE1/2OE2). Its CMOS architecture enables rail-to-rail input thresholds compliant with JEDEC JESD8-7A, JESD8-5A, and JESD8-C standards across 1.65 V–3.6 V operation.
Bus-hold circuitry sustains logic states on all data inputs (but not control inputs), with ±75 μA sustaining current at 3.0 V and ±500 μA overdrive capability. Outputs tolerate up to 5.5 V when disabled and remain high-impedance when VCC = 0 V - enabling hot-swap and power sequencing robustness in backplane and modular 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 without level shifters. |
| Propagation delay (tpd) | 1.0 ns to 5.5 ns (VCC = 3.0–3.6 V) - ensures sub-6 ns timing margin for 100+ MHz parallel bus applications. |
| Input voltage tolerance | –0.5 V to +5.5 V - allows safe connection to 5 V TTL/CMOS outputs while powered from 3.3 V or lower supplies. |
| Bus hold current | ±75 μA at VI = 0.8 V / 2.0 V (VCC = 3.0 V) - maintains stable logic state on floating inputs without external resistors. |
| Output drive strength | ±24 mA (VOH/VOL @ VCC = 3.0 V) - drives standard 50 pF loads with <0.8 V VOL and >2.2 V VOH under full load. |
| Operating temperature | –40 °C to +125 °C - qualified for industrial and extended-temperature embedded control and communications equipment. |
| ESD protection | HBM >2000 V, CDM >1000 V - meets JEDEC JS-001/JS-002 Class 2/C3 for robust handling in automated assembly environments. |
Pinout & Package
TSSOP48 (SOT362-1) package: plastic thin shrink small outline, 48 leads, 6.1 mm body width, 0.5 mm lead pitch, with 8 ground pins and 4 VCC pins for low-inductance power delivery and minimized ground bounce.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE1, 1OE2, 2OE1, 2OE2 | Active-low output enable inputs | Independent control of Group 1 (pins 1, 48) and Group 2 (pins 24, 25) 8-bit outputs; HIGH disables outputs to high-impedance state. |
| 1A0–1A7, 2A0–2A7 | Data inputs | Two independent 8-bit input banks (pins 37–47 and 26–36); all feature integrated bus-hold circuitry. |
| 1Y0–1Y7, 2Y0–2Y7 | 3-state buffered outputs | Non-inverting outputs (pins 2–12 and 13–23); tolerate up to 5.5 V when disabled and remain high-Z when VCC = 0 V. |
| VCC (pins 7, 18, 31, 42) | Positive supply | Four distributed VCC connections reduce supply inductance and improve noise immunity in high-speed switching. |
| GND (pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight dedicated GND pins provide low-impedance return paths and minimize simultaneous switching noise (SSN). |
Key Features
| Feature | Design Value |
|---|---|
| Dual 8-bit 3-state buffering | Independent enable control per group allows selective bus isolation - critical for multi-master arbitration and memory-mapped peripheral sharing. |
| 5 V-tolerant I/O | Inputs and outputs accept up to 5.5 V regardless of VCC (1.2–3.6 V), enabling seamless integration into legacy 5 V subsystems without external translators. |
| Integrated bus hold | Eliminates need for external pull-up/pull-down resistors on all 16 data inputs, reducing BOM count and PCB area in high-pin-count designs. |
| Low-noise power distribution | Multiple VCC/GND pins and flow-through pinout minimize ground bounce and crosstalk - verified by <1.5 ns output skew (tsk(o)) at 3.3 V. |
| Extended temperature operation | Specified from –40 °C to +125 °C with full static/dynamic performance guarantees - suitable for industrial motor drives and telecom line cards. |

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 |
|---|---|---|---|
| SN74LVC16244ADGGR | Single 16-bit bus with shared OE; no bus hold; 1.65–3.6 V only; 24 mA drive. | Lacks per-group OE control and bus hold - requires external pull-ups and cannot isolate half-bus segments. | Select when cost sensitivity outweighs need for independent channel control and floating-input robustness. |
| 74ALVCH162244DL,118 | Same pinout, wider VCC range (1.2–3.6 V), but no bus hold and lower ESD rating (HBM 2 kV vs. 2 kV, CDM 500 V vs. 1000 V). | Compatible drop-in replacement for legacy ALVC designs but lacks bus-hold reliability in unpopulated slots. | Select only if existing ALVC design migration is required and bus hold is not needed for system-level robustness. |
Compared with SN74LVC16244ADGGR and 74ALVCH162244DL,118, the 74LVCH16541ADL,112 uniquely combines dual independent OE control, integrated bus hold, and 5.5 V-tolerant I/O - making it the only option supporting fault-tolerant, mixed-voltage bus expansion without external components.

FAQ
Can 74LVCH16541ADL,112 be used with a 1.2 V supply?
Yes - the device is fully specified from 1.2 V to 3.6 V. At 1.2 V, propagation delay is ≤10.4 ns (typical 4.7 ns), input thresholds scale to 0.65×VCC, and output drive is reduced to ±100 μA. All static and dynamic parameters remain guaranteed across the full range, including –40 °C to +125 °C operation.
What happens to outputs when VCC = 0 V?
Outputs enter a true high-impedance state with ≤±0.1 μA off-state leakage (IOFF), even when up to 5.5 V is applied to output pins. This enables safe hot-plug operation and power sequencing where peripherals power up before or after the buffer's supply rail.
How does bus hold function interact with 5 V inputs?
The bus hold circuit automatically disables when input voltage exceeds VCC, allowing 5.5 V signals to pass through without damage or contention. Bus hold remains active only when VI ≤ VCC - ensuring compatibility with both 3.3 V and 5 V sources while protecting against floating inputs during idle states.
Is there a thermal derating curve for TSSOP48 package?
Yes - total power dissipation (Ptot) is rated at 500 mW up to +109 °C, then derates linearly at 12.2 mW/K above that temperature. At +125 °C ambient, maximum allowable Ptot is 481 mW. Thermal resistance θJA is 220 K/W (typical), measured per JEDEC JESD51-2 with 1-inch² 2-oz copper pad.
