Product details
Overview
74HCT541D-Q100 from Nexperia is an automotive-qualified octal non-inverting 3-state buffer/line driver in SO20 (SOT163-1) package, operating from 4.5 V to 5.5 V with TTL-compatible inputs, ±6 mA output drive, and propagation delay of 15 ns (typ) at VCC = 4.5 V - used for bidirectional data bus isolation in engine control units and body electronics.
For engineers reviewing the 74HCT541D-Q100 datasheet, 74HCT541D-Q100 pinout, 74HCT541D-Q100 application, or 74HCT541D-Q100 equivalent, key selection criteria include dual active-low output enables (OE1/OE2), AEC-Q100 Grade 1 qualification (-40 °C to +125 °C), input clamp diodes for overvoltage tolerance, and SO20 thermal derating (12.3 mW/K above 109 °C).
Technical Context
This device implements eight identical non-inverting buffer circuits with independent 3-state control via two active-low enable inputs (OE1, OE2). When either OE is HIGH, all eight outputs enter high-impedance OFF-state, enabling bus sharing without contention.
Input thresholds are TTL-compatible (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), while output drive meets ±6.0 mA at VOH ≥ 3.98 V and VOL ≤ 0.26 V under same conditions. Static current remains ≤160 μA across full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - matches standard automotive 5 V rail with 10% tolerance margin |
| Propagation Delay | 15 ns (typ) at VCC = 4.5 V, CL = 50 pF - supports >30 MHz bus toggle rates |
| Output Drive | ±6.0 mA - sufficient to drive 50 pF loads with <0.26 V VOL and >3.98 V VOH |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood applications |
| Input Compatibility | TTL-level inputs - interfaces directly with legacy 5 V microcontrollers and logic families |
| ESD Protection | HBM >2000 V, CDM >1000 V - exceeds automotive system-level ESD immunity requirements |
| Power Dissipation | 500 mW max (SO20), derates 12.3 mW/K above 109 °C - defines thermal design envelope |
Pinout & Package
SO20 plastic small outline package (SOT163-1), 7.5 mm body width, 20-pin gull-wing lead frame, JEDEC MS-013 compliant. Thermal resistance θJA = 82 K/W (typ), θJL = 32 K/W (typ).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 19 | OE1, OE2 | Active-low output enable inputs - either HIGH forces all Yn outputs into high-Z state |
| 2–9 | A0–A7 | Data inputs - non-inverting, TTL-compatible, with clamp diodes for overvoltage protection |
| 10 | GND | Ground reference - must be low-inductance connection to minimize switching noise |
| 11–18 | Y7–Y0 | Data outputs - 3-state, capable of sourcing/sinking ±6 mA with defined VOH/VOL |
| 20 | VCC | Supply voltage - decoupling capacitor (100 nF ceramic) required within 5 mm |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent output enables | OE1 and OE2 allow selective activation of subsets of outputs for partial bus control |
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, including lifetime reliability testing |
| Input clamp diodes | Enable safe interface to signals up to VCC + 0.5 V using external current-limiting resistors |
| Low static current | ICC ≤ 160 μA at VCC = 5.5 V and full temperature range - reduces standby power in always-on modules |
| High noise immunity | CMOS input structure with hysteresis-free TTL thresholds ensures robust operation in noisy vehicle environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HCT541QPWRQ1 | TSSOP20 package (SOT360-1), 4.4 mm body width, θJA = 100 K/W, Ptot derates 10.0 mW/K above 100 °C | Better suited for high-density layouts where board area is constrained but thermal budget allows lower power density | Select when PCB real estate is critical and thermal management uses internal copper planes rather than heatsinking. |
| 74HC541D-Q100 | CMOS input thresholds (VIH = 3.15 V min at VCC = 4.5 V), wider 2.0–6.0 V supply range, higher ICC (160 μA max) | Compatible with mixed-voltage systems (e.g., 3.3 V logic driving 5 V bus), less tolerant of marginal input levels | Select when interfacing with CMOS outputs or multi-rail designs requiring flexible VCC operation beyond 5 V. |
Compared with SN74HCT541QPWRQ1, the 74HCT541D-Q100 offers superior thermal performance in convection-cooled environments due to SO20's lower θJA; compared with 74HC541D-Q100, it provides guaranteed TTL-level compatibility essential for legacy 5 V microcontroller interfaces.

FAQ
Can 74HCT541D-Q100 operate at 3.3 V supply?
No. The 74HCT541D-Q100 is specified only for 4.5 V to 5.5 V operation per its recommended conditions table. At 3.3 V, input thresholds fall outside TTL compatibility (VIH minimum becomes undefined), and output drive degrades below guaranteed ±6 mA. Use 74HC541D-Q100 for 2.0–6.0 V flexibility.
What is the maximum capacitive load this device can drive reliably?
The device is characterized up to 50 pF (CL = 50 pF in dynamic specs), with propagation delay increasing to 42 ns max at VCC = 4.5 V. For loads >50 pF, transition times lengthen and VOL/VOH margins shrink; add series termination or reduce trace length to maintain signal integrity.
How do OE1 and OE2 interact when both are asserted?
Both OE1 and OE2 are active-low and OR-connected logically: if either is HIGH, all outputs go high-impedance. Only when both are LOW do outputs follow inputs. This allows fail-safe disable using either control line independently.
Is there a recommended PCB layout practice for minimizing ground bounce?
Place a 100 nF X7R ceramic decoupling capacitor between VCC (pin 20) and GND (pin 10) with trace length <5 mm. Route GND pin 10 directly to a solid ground plane; avoid daisy-chaining GND connections to other ICs to prevent shared impedance coupling.
