Product details
Overview
74LV541DB,112 from NXP Semiconductors is an octal non-inverting 3-state buffer/line driver in SSOP20 package, operating from 1.0 V to 3.6 V supply, with dual active-low output enable (OE1/OE2), −40 °C to +125 °C temperature range, and TTL-level input compatibility at VCC ≥ 2.7 V. It serves as a bus interface or data isolation device in low-voltage digital systems.
For engineers reviewing the 74LV541DB,112 datasheet, 74LV541DB,112 pinout, 74LV541DB,112 application, or 74LV541DB,112 equivalent, key selection considerations include its 3-state control architecture, propagation delay of 10 ns (typical at VCC = 3.3 V, CL = 15 pF), output drive capability of ±8 mA, ground bounce < 0.8 V, and ESD robustness (HBM > 2000 V).
Technical Context
The 74LV541DB,112 implements eight independent non-inverting buffer channels, each with high-impedance (Z) output state controlled by two shared active-low enable inputs (OE1 and OE2). Its CMOS Si-gate process enables rail-to-rail output swing and low static current (ICC ≤ 20 µA typical at VCC = 3.6 V).
Functional behavior follows a strict truth table: outputs Y0–Y7 enter high-impedance when either OE1 or OE2 is HIGH; outputs replicate A0–A7 only when both OE1 and OE2 are LOW. Input thresholds are specified for VCC = 1.2 V, 2.0 V, and 2.7–3.6 V, supporting mixed-voltage interfacing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.0 V to 3.6 V - supports direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters. |
| Propagation Delay (tpd) | 10 ns (typ) at VCC = 3.3 V, CL = 15 pF - enables reliable operation in 50 MHz+ address/data bus applications. |
| Output Drive | ±8 mA at VCC = 3.0 V - sufficient to drive 15 pF loads across PCB traces or multiple CMOS inputs. |
| Input Thresholds | VIH = 2.0 V, VIL = 0.8 V at VCC = 3.3 V - ensures compatibility with standard TTL outputs and 3.3 V LVTTL. |
| ESD Protection | HBM > 2000 V, MM > 200 V - meets industrial handling requirements without external protection circuitry. |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive, industrial control, and extended-range embedded systems. |
| Power Dissipation | 500 mW max (SSOP20) - allows sustained operation in compact, thermally constrained layouts. |
Pinout & Package
74LV541DB,112 uses the SSOP20 (SOT339-1) package: plastic shrink small outline, 20 leads, 5.3 mm body width, 0.65 mm lead pitch, and gull-wing surface-mount terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE1) | Active-low output enable | Asserting HIGH disables all eight outputs into high-impedance; shared control with OE2 for grouped bus isolation. |
| 2–9 (A0–A7) | Data inputs | Non-inverting inputs accepting 1.0–3.6 V logic levels; TTL-compatible when VCC ≥ 2.7 V. |
| 10 (GND) | Ground reference | Primary return path for all I/O and supply currents; must be low-inductance connection to minimize ground bounce. |
| 11–18 (Y0–Y7) | Buffered outputs | Non-inverting, 3-state outputs capable of sourcing/sinking 8 mA; exhibit < 0.8 V ground bounce at 3.3 V. |
| 19 (OE2) | Active-low output enable | Second enable input - both OE1 and OE2 must be LOW for outputs to drive; provides redundancy or split-bus control. |
| 20 (VCC) | Supply voltage | Single 1.0–3.6 V supply powering all logic and output stages; decoupling capacitor required near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Low-voltage operation | Functional down to 1.0 V supply - enables integration into ultra-low-power battery-backed or energy-harvesting subsystems. |
| TTL input compatibility | Accepts standard TTL logic levels when VCC ≥ 2.7 V - eliminates need for external level translators in mixed-technology systems. |
| Controlled output transition | Typical ground bounce < 0.8 V at VCC = 3.3 V - reduces noise coupling into adjacent signal or analog circuits. |
| High-temperature rating | Specified from −40 °C to +125 °C - supports deployment in engine control units, motor drives, and industrial PLCs. |
| Multiple package options | SSOP20 footprint (SOT339-1) offers 35 % area reduction vs SO20 - ideal for space-constrained PCBs without sacrificing thermal performance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal buffer/line driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC541APW,118 | Lower ICC (10 µA typ), tighter VOH/VOL specs at 1.8 V, same SSOP20 package and pinout. | Better suited for 1.8 V core logic; slightly faster tpd (8.5 ns typ at VCC = 1.8 V, CL = 15 pF). | Select when primary system voltage is 1.8 V and ultra-low static power is critical. |
| SN74LV541ADBR | TI variant with identical electrical specs, same SSOP20 (DB) package, but different marking and reel packaging. | No functional difference; qualified for same industrial temperature range (−40 °C to +125 °C). | Choose for dual-sourcing flexibility or existing TI supply chain alignment. |
Compared with 74LV541DB,112, the 74LVC541APW,118 delivers superior performance below 2.0 V supply, while the SN74LV541ADBR offers identical functionality with alternate logistics packaging - both preserve the same 3-state control architecture and thermal envelope.

FAQ
What is the minimum supply voltage for reliable operation of the 74LV541DB,112?
The 74LV541DB,112 is guaranteed to function down to 1.0 V supply voltage, with static characteristics fully specified from 1.2 V to 3.6 V. At VCC = 1.0 V, inputs must be driven to GND or VCC for correct logic interpretation, and propagation delay increases to 60 ns (typ). This makes the 74LV541DB,112 suitable for ultra-low-power battery-operated systems where supply rails dip near 1.0 V.
Does the 74LV541DB,112 support TTL-level inputs?
Yes, the 74LV541DB,112 accepts standard TTL input voltage levels when VCC is between 2.7 V and 3.6 V. Specifically, VIH is guaranteed ≥ 2.0 V and VIL ≤ 0.8 V under those conditions, matching TTL output specifications. This eliminates the need for external level-shifting circuitry when interfacing with legacy 5 V TTL devices operating at reduced output swing.
How does the dual output enable (OE1 and OE2) function in the 74LV541DB,112?
In the 74LV541DB,112, both OE1 (pin 1) and OE2 (pin 19) are active-low enables. All eight outputs (Y0–Y7) enter high-impedance only if at least one of OE1 or OE2 is HIGH. Outputs drive only when both OE1 and OE2 are LOW. This architecture allows flexible bus control - for example, OE1 can serve as primary enable while OE2 acts as fault-safety override or secondary domain isolation signal.
What is the maximum capacitive load the 74LV541DB,112 can drive reliably?
The 74LV541DB,112 is characterized for dynamic performance with 15 pF and 50 pF loads. Propagation delay is specified as 10 ns (typ) at VCC = 3.3 V with CL = 15 pF, and 23 ns (max) at VCC = 3.0 V to 3.6 V with CL = 50 pF. For reliable signal integrity beyond 50 pF, series termination or reduced edge rates should be applied - the 74LV541DB,112 itself does not include slew-rate control.
Is the 74LV541DB,112 pin-compatible with the 74HC541 and 74HCT541?
Yes, the 74LV541DB,112 is explicitly stated as pin and function compatible with both 74HC541 and 74HCT541. The pin configuration (including OE1, A0–A7, Y0–Y7, OE2, GND, VCC) matches exactly across all three families. However, note that the 74LV541DB,112 operates at lower voltages (1.0–3.6 V) and exhibits different timing and drive strength - direct substitution is electrically valid only within its specified VCC range.
