Product details
Overview
74HC241DB,112 from Nexperia is an octal non-inverting 3-state buffer/line driver in SO20 (SOT163-1) package, featuring dual independent output enables (1OE active LOW, 2OE active HIGH) controlling two groups of four outputs each. It operates from 2.0 V to 6.0 V, delivers propagation delay as low as 7 ns at VCC = 6.0 V, and supports industrial temperature range (−40 °C to +125 °C). It is used for bidirectional bus interfacing in digital logic systems requiring high noise immunity and CMOS-level input compatibility.
For engineers reviewing the 74HC241DB,112 datasheet, 74HC241DB,112 pinout, 74HC241DB,112 application, or 74HC241DB,112 equivalent, key selection criteria include dual 3-state enable architecture, SO20 package footprint, guaranteed 7 ns max propagation delay at 6 V, −40 °C to +125 °C operation, and compatibility with 2.0–6.0 V supply rails.
Technical Context
The device implements two independent 4-bit non-inverting buffers, each with dedicated 3-state control: 1OE (pin 1, active LOW) enables outputs 1Y0–1Y3, while 2OE (pin 19, active HIGH) enables outputs 2Y0–2Y3. Input clamp diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors.
It complies with JEDEC JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V), meets HBM ESD >2000 V and CDM >1000 V, and exhibits latch-up immunity exceeding 100 mA per JESD78 Class II Level B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - Enables direct interface with 3.3 V and 5 V logic domains without level shifters. |
| Propagation Delay (tpd) | 7 ns (typ) at VCC = 6.0 V - Supports high-speed data transfer up to ~70 MHz in buffered bus paths. |
| Output Drive Strength | ±6.0 mA (IOH/IOL) at VCC = 4.5 V - Sufficient to drive 15 pF loads with <30 ns transition times. |
| Input Thresholds | CMOS-compatible (VIH = 0.7×VCC, VIL = 0.3×VCC) - Ensures robust noise margin across full supply range. |
| Operating Temperature | −40 °C to +125 °C - Qualified for industrial and extended-temperature embedded control applications. |
| Power Dissipation | 500 mW (SO20 package, derated above 109 °C) - Supports continuous operation under moderate thermal load. |
| Input Capacitance | 3.5 pF - Minimizes capacitive loading on upstream drivers and preserves signal integrity. |
Pinout & Package
74HC241DB,112 is housed in a plastic small outline package (SO20, SOT163-1) with 20 leads and 7.5 mm body width. Pin 1 is marked by a notch or dot; pin numbering follows standard counter-clockwise convention starting from pin 1 at top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (1OE) | Output Enable 1 | Active-LOW control for outputs 1Y0–1Y3; asserts high-impedance state when HIGH. |
| 2–8 (1A0–1A3, GND, 2A0–2A2) | Data Inputs / Ground | Group 1 inputs (pins 2,4,6,8); Group 2 inputs (pins 17,15,13,11); GND (pin 10) serves as reference for all I/O and supply. |
| 11–19 (2A2, 2A1, 2A0, 2Y0–2Y3, 2OE) | Data Inputs / Outputs / Enable | Pins 17,15,13,11 = 2A3–2A0; pins 3,5,7,9 = 2Y0–2Y3; pin 19 = 2OE (active HIGH). |
| 12–18 (1Y3–1Y0) | Group 1 Outputs | Pins 12,14,16,18 = 1Y3,1Y2,1Y1,1Y0 - non-inverting, 3-state outputs enabled by 1OE. |
| 20 (VCC) | Supply Voltage | Primary power rail (2.0–6.0 V); decoupling capacitor required near pin for stable switching. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 3-state control | Separate 1OE (active LOW) and 2OE (active HIGH) allow asymmetric bus arbitration and partial bus isolation. |
| Input clamp diodes | Enable safe overvoltage tolerance (VI > VCC) when used with series current-limiting resistors. |
| Wide supply voltage range | 2.0 V to 6.0 V operation eliminates need for separate voltage translators in mixed-supply systems. |
| High noise immunity | CMOS input structure with >40% noise margin ensures reliable operation in electrically noisy industrial environments. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during transient overcurrent events. |
Applications

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 |
|---|---|---|---|
| 74HCT241DB,112 | TTL-compatible inputs (VIH = 2.0 V min), otherwise identical pinout, timing, and package. | Required when driving from 5 V TTL sources; not suitable for pure CMOS systems below 4.5 V. | Select when interfacing legacy 5 V TTL logic; verify VIH/VIL thresholds match source driver specs. |
| SN74LVC244APWR | 3.3 V only (1.65–3.6 V), lower propagation delay (3.3 ns typ), different pinout (16-pin TSSOP). | Optimized for low-voltage, high-speed applications; lacks dual OE architecture and 5 V tolerance. | Choose for 3.3 V-only designs needing faster timing; requires PCB redesign due to pin mismatch and package change. |
Compared with 74HC241DB,112, the 74HCT241DB,112 offers guaranteed TTL input compatibility but sacrifices 2.0–4.4 V operation, while SN74LVC244APWR provides superior speed and lower voltage operation at the cost of supply flexibility, pin compatibility, and dual-enable functionality.

FAQ
What is the maximum clock frequency supported by 74HC241DB,112 in a buffered data path?
The device does not operate as a clocked element but as a combinatorial buffer. Its 7 ns typical propagation delay at 6 V implies usable data rates up to ~70 MHz in point-to-point paths with 15 pF load. Actual maximum frequency depends on trace length, termination, and fan-out; for 20 cm PCB traces with 10 pF load, reliable operation is confirmed to 25 MHz per manufacturer characterization.
Can 74HC241DB,112 safely interface a 3.3 V microcontroller to a 5 V peripheral bus?
Yes - its 2.0–6.0 V supply range allows VCC = 5 V operation, and its CMOS inputs accept 3.3 V as valid HIGH (VIH ≥ 3.5 V at VCC = 5 V per datasheet). No level shifter is needed. However, ensure the microcontroller's 3.3 V outputs meet the 74HC241's VIH minimum (3.5 V) under worst-case conditions; if not, use 74HCT241DB,112 instead.
How does the dual output enable (1OE and 2OE) improve system design flexibility?
Dual OE allows independent control of two 4-bit output groups - e.g., one group for address lines and another for data lines - enabling selective bus isolation without disabling the entire device. This supports partial bus arbitration, reduces switching noise, and simplifies timing-critical operations like memory-mapped I/O access where address and data phases must be gated separately.
Is 74HC241DB,112 qualified for automotive applications?
No - this part is specified for industrial temperature range (−40 °C to +125 °C) but is not AEC-Q100 qualified. Nexperia explicitly states in its legal disclaimers that non-automotive qualified products are unsuitable for safety-critical or life-support systems. For automotive use, consult Nexperia's dedicated automotive-grade logic portfolio with formal qualification documentation.
