Product details

Overview

74HCT241PW,112 from Nexperia is an octal non-inverting 3-state buffer/line driver with dual independent output enables (1OE active LOW, 2OE active HIGH), TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 5 V), 20-pin TSSOP package, and operation from −40 °C to +125 °C. It serves as bidirectional bus interface or level-shifting driver in industrial control backplanes and legacy system upgrades.

For engineers reviewing the 74HCT241PW,112 datasheet, 74HCT241PW,112 pinout, 74HCT241PW,112 application, or 74HCT241PW,112 equivalent, key selection criteria include TTL-level input compatibility, dual 4-bit enable control, 3-state output leakage (±5 μA max), propagation delay (13 ns typ at VCC = 4.5 V), and TSSOP20 thermal derating (10.0 mW/K above 100 °C).

Technical Context

This device implements two independent 4-bit buffered paths: inputs 1A0–1A3 drive outputs 1Y0–1Y3 under control of 1OE (active LOW); inputs 2A0–2A3 drive outputs 2Y0–2Y3 under control of 2OE (active HIGH). Each output exhibits non-inverting logic and high-impedance OFF-state when its enable is inactive.

Input clamp diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors. The 74HCT variant's reduced input thresholds (vs. 74HC) ensure reliable recognition of standard TTL logic levels across the full −40 °C to +125 °C temperature range.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply voltage	4.5 V to 5.5 V - matches standard 5 V TTL systems without level translation
Propagation delay	13 ns typical (nAn → nYn, CL = 15 pF, VCC = 5 V) - supports >30 MHz bus toggle rates
Output drive	±6 mA (VOH/VOL at VCC = 4.5 V) - sufficient for driving 10 LSTTL loads or 50 Ω transmission lines
Input threshold	VIH = 2.0 V min, VIL = 0.8 V max - guarantees interoperability with 5 V TTL outputs
Off-state leakage	±5.0 μA max (IOZ, VCC = 5.5 V) - prevents unintended loading of shared buses during disable
Operating temperature	−40 °C to +125 °C - qualified for extended industrial and under-hood applications

Input clamp diodes	Enable safe overvoltage tolerance (VI > VCC) when series resistors limit current to <20 mA
High noise immunity	Typical noise margin >1.0 V at VCC = 5 V due to CMOS input structure and hysteresis-free design
JEDEC-compliant 3-state	IOZ ≤ ±5 μA at VCC = 5.5 V ensures minimal bus contention during output disable

Applications

Embedded Data Acquisition Multiplexing

Use Scenario: Routing multiple sensor data streams onto a shared 8-bit parallel acquisition bus in modular ATE racks.

IC Role / Device Role / Timing Role: 3-state line driver enabling time-multiplexed access to shared bus by enabling only one channel at a time.

Use Value: Low propagation delay (13 ns typ) and fast enable/disable times (<45 ns) support precise timing-critical sampling sequences.

Use Scenario: Consolidating analog front-end digital control lines (e.g., ADC channel select, DAC update) into a single 8-bit control bus.

IC Role / Device Role / Timing Role: Non-inverting octal buffer providing fan-out and drive strength for synchronous control signals distributed across PCB layers.

Use Value: ±6 mA output drive sustains signal integrity over 10 cm traces with 50 pF load, eliminating need for additional drivers.

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
SN74HCT241PW	Identical pinout, function, and electrical specs; Texas Instruments version with same 4.5–5.5 V range and −40 °C to +125 °C rating	No functional difference; suitable for TI-centric BOMs or dual-sourcing strategies	Select when TI qualification or long-term availability assurance is required
74HCT244PW,118	Octal non-inverting buffer with single active-LOW enable (OE); lacks dual-enable architecture of 74HCT241	Cannot independently control two 4-bit groups; requires external logic for segmented enable	Choose only if simplified enable scheme suffices and dual-group isolation is unnecessary

Compared with SN74HCT241PW, this Nexperia part offers identical functionality but distinct supply chain traceability; versus 74HCT244PW,118, it provides superior bus segmentation capability via dedicated 1OE/2OE controls-critical for fault-containment in multi-module systems.

FAQ

Can 74HCT241PW,112 operate reliably at 3.3 V supply?

No. The 74HCT241PW,112 is specified only for 4.5 V to 5.5 V operation per its recommended conditions. At 3.3 V, input thresholds (VIH = 2.0 V min) may not be met by standard 3.3 V logic, and output drive strength degrades significantly. Use 74LVC241 or 74ALVC241 for true 3.3 V compatibility.

What is the maximum capacitive load this device can drive while maintaining timing specs?

The datasheet specifies timing (tpd, ten, tdis) with CL = 15 pF. While the device can drive heavier loads, propagation delay increases linearly with capacitance-e.g., at CL = 50 pF, tpd rises to ~22 ns (VCC = 4.5 V). For loads >30 pF, verify setup/hold margins in your specific timing budget.

How does the dual-enable architecture improve system reliability?

Independent 1OE (active LOW) and 2OE (active HIGH) allow hardware-level partitioning: one group can remain enabled while the other is safely disabled during hot-swap events or fault recovery. This prevents bus contention and eliminates race conditions that occur with single-enable octal buffers during state transitions.

Is the TSSOP20 package RoHS and REACH compliant?

Yes. Nexperia confirms the 74HCT241PW,112 in SOT360-1 (TSSOP20) meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, including SVHC screening. Full compliance documentation is available via Nexperia's product change notifications portal.
