Product details
Overview
74HC241D,653 from Nexperia is an octal non-inverting 3-state buffer/line driver in SO20 (SOT163-1) package, operating from 2.0 V to 6.0 V supply. It features dual independent output enables (1OE active LOW, 2OE active HIGH), each controlling four outputs, and supports CMOS-level inputs with clamp diodes for overvoltage-tolerant interfacing. Used in bidirectional bus isolation and address/data buffering in industrial control and instrumentation systems.
For engineers reviewing the 74HC241D,653 datasheet, 74HC241D,653 pinout, 74HC241D,653 application, or 74HC241D,653 equivalent, key selection criteria include dual 4-bit enable control logic, 3-state output leakage < ±10 μA at 125 °C, propagation delay of 7 ns (VCC = 6.0 V), and SO20 thermal derating (12.3 mW/K above 109 °C).
Technical Context
The device implements two independent 4-bit buffer sections sharing a common VCC/GND rail, with logically separated 3-state control: 1OE (pin 1, active LOW) enables outputs 1Y0–1Y3, while 2OE (pin 19, active HIGH) enables 2Y0–2Y3. Input clamping diodes allow safe interface to signals exceeding VCC when used with current-limiting resistors.
Its CMOS architecture delivers high noise immunity (>50% VCC), latch-up immunity >100 mA (JESD78 Class II Level B), and operates across −40 °C to +125 °C. Static input thresholds scale with VCC (VIH = 0.7×VCC min, VIL = 0.3×VCC max), ensuring robust logic-level compatibility within its 2.0–6.0 V range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 2.0 V to 6.0 V - supports mixed-voltage system interfacing and battery-backed operation down to 2 V. |
| Propagation delay | 7 ns (typ) at VCC = 6.0 V - enables reliable timing in 70+ MHz bus applications with 15 pF load. |
| Output drive | ±7.8 mA (VOH/VOL) at VCC = 4.5 V - sufficient to drive 10 LSTTL loads or 20 pF PCB traces without external buffers. |
| Off-state leakage | ±10 μA max at −40 °C to +125 °C - ensures minimal bus contention current during 3-state hold in hot industrial environments. |
| Input clamp current | ±20 mA - permits direct connection to 12 V control signals via 1 kΩ series resistor without damage. |
| Power dissipation | 500 mW max (SO20), derates 12.3 mW/K above 109 °C - defines thermal design margin for continuous 8-bit bus switching at full speed. |
| Operating temperature | −40 °C to +125 °C - qualified for under-hood automotive modules and industrial PLC backplanes. |
Pinout & Package
74HC241D,653 uses the SO20 plastic small outline package (SOT163-1), 7.5 mm body width, 20-pin gull-wing lead frame, JEDEC MS-013 compliant, with 1.27 mm pitch and 0.4–0.65 mm lead thickness.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (1OE) | Output enable 1 | Active-LOW control for outputs 1Y0–1Y3; ties to GND or microcontroller GPIO for section gating. |
| 2–8 (1A0–1A3, 2A0–2A3) | Data inputs | Two independent 4-bit input groups (pins 2,4,6,8 and 11,13,15,17); non-inverting, CMOS-compatible. |
| 9–10,12,14,16,18 (2Y0–2Y3, 1Y0–1Y3) | Data outputs | Non-inverting 3-state outputs (2Y0–2Y3 on pins 3,5,7,9; 1Y0–1Y3 on pins 12,14,16,18); high-Z when disabled. |
| 19 (2OE) | Output enable 2 | Active-HIGH control for outputs 2Y0–2Y3; allows synchronous or asynchronous bus partitioning. |
| 20 (VCC) | Supply voltage | Primary power rail; decoupling capacitor (100 nF) required within 5 mm for stable 3-state transitions. |
| 10 (GND) | Ground reference | Common return path for all I/O and supply currents; must be low-inductance plane for EMI control. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 4-bit enables | 1OE (active LOW) and 2OE (active HIGH) allow asymmetric bus arbitration - e.g., one section held active while other responds to interrupt-driven data bursts. |
| Input clamp diodes | Enable safe 5 V/12 V signal injection into 3.3 V systems using series resistors, eliminating need for level translators in sensor interface stages. |
| High-temperature operation | Specified up to +125 °C ambient with full parameter compliance - supports deployment in motor drive enclosures and power supply control boards. |
| Low dynamic power | CPD = 30 pF per buffer - limits switching power to < 1.5 mW per channel at 10 MHz, critical for thermally constrained embedded designs. |
| JEDEC-compliant 3-state behavior | IOZ ≤ ±10 μA at VCC = 6.0 V and T = 125 °C - guarantees bus integrity during hot-swap or partial system reset sequences. |
Applications
| Industrial PLC Backplane | Automotive Body Control Module |
|---|---|
Use Scenario: Isolating CPU address/data bus from multiple peripheral cards in modular rack-mounted controllers. IC Role / Device Role / Timing Role: Bidirectional 8-bit buffer with independent enable control prevents bus contention during card insertion/removal and firmware updates.

IC Role / Device Role / Timing Role: Voltage-tolerant input buffer with clamp diodes; provides level shifting without external components. Use Value: Eliminates need for discrete resistors and Schottky diodes, saving 35 mm² PCB area per channel and improving long-term reliability. |
| Test Equipment Signal Routing | Legacy System Bus Extension |
Use Scenario: Multiplexing DUT signals between multiple measurement instruments in automated test fixtures. IC Role / Device Role / Timing Role: Low-propagation-delay 3-state driver enabling precise timing-controlled signal path selection. Use Value: 7 ns tPD at 6 V ensures sub-10 ns path switching jitter, meeting IEEE 1149.1 boundary-scan timing budgets. | Use Scenario: Extending ISA or PCI bus segments in retrofitted industrial PCs where trace length exceeds specification. IC Role / Device Role / Timing Role: Active repeater buffer restoring signal edge integrity and driving capacitive loads beyond 100 pF. Use Value: ±7.8 mA drive strength maintains 2 V/ns slew rate into 50 pF loads, preventing setup/hold violations on legacy peripherals. |
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 |
|---|---|---|---|
| SN74HC241N | DIP-20 package; no thermal derating curve published; VIH/VIL thresholds identical but lower ESD rating (HBM 2 kV vs 2 kV, CDM not specified). | Limited to lab prototyping or low-volume through-hole assembly; unsuitable for reflow-soldered industrial production. | Select only if DIP footprint and hand-soldering are mandatory; SO20 offers superior thermal performance and automated assembly compatibility. |
| 74LVC241APW | TSSOP20 (SOT360-1); 1.65–3.6 V supply; 3.3 V logic only; 3.5 ns tPD at 3.3 V; IO = ±24 mA. | Optimized for modern low-voltage digital systems; incompatible with 5 V buses or mixed-supply domains. | Choose for new 3.3 V designs requiring faster switching and lower power; avoid when interfacing legacy 5 V peripherals or wide-VCC flexibility is needed. |
Compared with SN74HC241N and 74LVC241APW, the 74HC241D,653 uniquely balances wide supply range (2–6 V), industrial temperature support (−40 to +125 °C), and SO20 thermal management - making it the only option qualified for high-reliability, mixed-voltage, surface-mount production environments.

FAQ
Can 74HC241D,653 interface directly with 5 V TTL logic?
No - the 74HC241 variant has CMOS input thresholds (VIH ≥ 0.7×VCC), so at VCC = 5 V, VIH min = 3.5 V, which is insufficient for standard TTL's 2.0 V VIH. Use the pin-compatible 74HCT241D for TTL-level compatibility, as its VIH is fixed at 2.0 V regardless of VCC.
What is the maximum capacitive load this device can drive reliably?
At VCC = 5 V and Tamb = 25 °C, the device maintains 2 V/ns minimum slew rate into 50 pF loads (per Table 7). For sustained operation across −40 °C to +125 °C, limit total load to 30 pF to ensure tPLH/tPHL remains within 30 ns and VOL stays ≤ 0.4 V at 6 mA sink current.
How does the dual OE architecture improve system-level fault tolerance?
Independent 1OE (active LOW) and 2OE (active HIGH) allow one 4-bit segment to remain active while the other enters high-Z during error recovery or partial reset. This prevents bus lockup in multi-peripheral systems - for example, holding CAN transceiver address lines active while resetting SPI peripherals on the same bus.
Is the SO20 package RoHS and REACH compliant?
Yes - the 74HC241D,653 (SOT163-1) meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free terminations and halogen-free molding compound. Full compliance documentation, including substance declarations and test reports, is available upon request from Aetrix Electronics.
