Product details
Overview
TC7W241FUTE12LF from Toshiba is a dual non-inverting 3-state bus buffer IC with independent active-high and active-low output enables, fabricated in silicon gate C2MOS technology. It operates from 2 V to 6 V, delivers 6 mA output drive per channel, achieves 10 ns typical propagation delay at 5 V, and supports industrial temperature range (−40°C to +85°C) - used in bidirectional data bus isolation and level translation in embedded control systems.
For engineers reviewing the TC7W241FUTE12LF datasheet, TC7W241FUTE12LF pinout, TC7W241FUTE12LF application, or TC7W241FUTE12LF equivalent, key selection criteria include dual-channel 3-state control timing, rail-to-rail input compatibility, low ICC (2 µA max), high noise immunity (28% VCC min), and SOIC-8 package suitability for space-constrained PCBs.
Technical Context
The TC7W241FUTE12LF implements two independent non-inverting buffers, each with separate enable inputs: one active-high (G1), one active-low (G2). Output states are high-impedance when disabled, enabling bus sharing without contention. Propagation delays are balanced (tpLH ≈ tpHL), supporting clean signal edge alignment in synchronous data paths.
It uses C2MOS process to achieve LSTTL-speed performance (10 ns typ. tpd at 5 V) while maintaining CMOS-level quiescent current (2 µA max). Input thresholds scale with VCC (VIH ≥ 3.15 V at 4.5 V; VIL ≤ 1.35 V), and outputs drive up to 15 LSTTL loads with symmetrical |IOH| = IOL = 6 mA (min) at VCC = 4.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 2 V to 6 V - supports mixed-voltage system interfacing (e.g., 3.3 V MCU to 5 V peripheral) |
| Propagation delay (tpd) | 10 ns (typ.) at VCC = 5 V - enables reliable operation in 25 MHz+ digital control buses |
| Output drive | 6 mA (min) sink/source - sufficient to drive 15 LSTTL loads without external buffering |
| Quiescent current (ICC) | 2 µA (max) at Ta = 25°C - enables ultra-low-power standby in battery-backed systems |
| Noise immunity | VNIH/VNIL = 28% VCC (min) - ensures robust operation in electrically noisy industrial environments |
| Operating temperature | −40°C to +85°C - qualified for industrial-grade embedded applications |
| Input capacitance | 5 pF (max) - minimizes loading on upstream drivers and preserves signal integrity |
Pinout & Package
TC7W241FUTE12LF is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package with standard 1.27 mm pitch, JEDEC MS-012AC compliant, and surface-mount compatible. Pin 1 is marked with a dot or bevelled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G1) | Active-high output enable | Drives Y1 high-impedance when low; enables non-inverted A1→Y1 path when high |
| 2 (A1) | Input 1 | Non-inverting data input for first buffer channel |
| 3 (Y1) | Output 1 | Non-inverted buffered output; high-impedance when G1 = low |
| 4 (G2) | Active-low output enable | Drives Y2 high-impedance when high; enables A2→Y2 path when low |
| 5 (A2) | Input 2 | Non-inverting data input for second buffer channel |
| 6 (Y2) | Output 2 | Non-inverted buffered output; high-impedance when G2 = high |
| 7 (VCC) | Positive supply | Power rail connection; must be decoupled locally (0.1 µF ceramic) |
| 8 (GND) | Ground reference | Return path for all signals and supply current |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 3-state control | Separate active-high and active-low enables allow flexible bus arbitration without external logic |
| Rail-to-rail input compatibility | Inputs accept 0 V to VCC levels across full 2–6 V supply range - simplifies interface with diverse logic families |
| Balanced propagation delays | tpLH ≈ tpHL minimizes duty cycle distortion in clocked or strobed data paths |
| ESD-protected inputs | Integrated protection circuits withstand ±20 mA input diode current - reduces need for external TVS |
| Low dynamic power | CPD = 33 pF enables predictable ICC(opr) calculation: ICC = CPD × VCC × fIN + ICC/2 per gate |
Applications
| Industrial PLC I/O Expansion | Automotive Body Control Module |
|---|---|
Use Scenario: Isolating microcontroller GPIOs from high-noise sensor/actuator buses in modular I/O racks. IC Role / Device Role / Timing Role: Dual 3-state buffer providing direction-controlled data routing between MCU and isolated CAN/LIN transceivers or analog front-ends. Use Value: Enables hot-swappable module detection via controlled bus release (high-Z) and prevents back-driving during insertion/removal. | Use Scenario: Level-shifting and bus isolation between 3.3 V domain (MCU) and 5 V domain (legacy lighting or relay drivers). IC Role / Device Role / Timing Role: Non-inverting buffer with independent enables managing bi-directional communication on shared diagnostic lines (e.g., K-line). Use Value: Maintains signal integrity across voltage domains while meeting automotive transient immunity requirements (via 28% VCC noise margin). |
| Medical Instrument Data Acquisition | Test & Measurement Equipment |
Use Scenario: Multiplexing analog sensor signals into ADC inputs while preventing crosstalk and ground loops. IC Role / Device Role / Timing Role: Bus buffer acting as digitally controlled analog switch driver - isolating ADC reference and sampling paths. Use Value: Low ICC (2 µA max) extends battery life in portable devices; high Z-state leakage <±0.5 µA avoids signal drift during acquisition hold. | Use Scenario: Synchronizing trigger and data lines between FPGA-based pattern generators and DUT interfaces. IC Role / Device Role / Timing Role: Timing-critical buffer ensuring matched rise/fall times (tTLH/tTHL ≤ 12 ns at 4.5 V) and minimal skew between parallel control lines. Use Value: Balanced tpLH/tpHL (≤18 ns max) guarantees deterministic setup/hold margins for 50 MHz digital stimulus waveforms. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G241DBVR | 3.3 V only (1.65–5.5 V), lower tpd (3.7 ns typ.), higher IOL (24 mA), no active-low enable | Requires redesign of enable logic; better suited for high-speed 3.3 V-only systems | Choose when speed >100 MHz timing and single-supply 3.3 V operation are mandatory |
| 74AHC241PW,118 | Wider VCC (2–5.5 V), higher ICC (100 µA max), same dual-enable architecture, TSSOP-20 package | Larger footprint; higher static power limits use in always-on battery systems | Prefer when legacy AHC family compatibility or higher drive strength (8 mA) under 5 V is required |
Compared with SN74LVC2G241DBVR and 74AHC241PW,118, the TC7W241FUTE12LF offers unique dual-polarity enable control in SOIC-8, lowest ICC for intermittent-bus applications, and proven industrial temperature reliability - making it optimal for cost-sensitive, mixed-voltage, and low-quiescent designs.

FAQ
What is the maximum operating voltage for TC7W241FUTE12LF?
The TC7W241FUTE12LF supports a supply voltage range of 2 V to 6 V, with absolute maximum rating of −0.5 V to +7 V on VCC. Continuous operation above 6 V is not recommended, as it exceeds the specified operating range and may compromise reliability or parametric performance. Always maintain VCC within 2–6 V for guaranteed functionality across −40°C to +85°C.
Does TC7W241FUTE12LF support 3.3 V logic levels?
Yes, TC7W241FUTE12LF fully supports 3.3 V operation: VIH(min) = 2.0 V at VCC = 3.3 V (interpolated from 2.0 V and 4.5 V specs), VIL(max) = 0.99 V, and VOH/VOL meet 3.3 V LVTTL thresholds. Its rail-to-rail input tolerance and 6 mA drive ensure interoperability with 3.3 V MCUs and peripherals without level shifters.
What is the function of Pin 4 (G2) on TC7W241FUTE12LF?
Pin 4 (G2) is the active-low output enable for the second buffer channel. When G2 = high, Y2 enters high-impedance state regardless of A2; when G2 = low, Y2 follows A2 non-inverted. This allows independent control of Y2 alongside Pin 1 (G1) for Y1, enabling asymmetric bus arbitration schemes in multi-master systems.
Is TC7W241FUTE12LF RoHS compliant?
Yes, TC7W241FUTE12LF is RoHS compliant and lead-free, consistent with Toshiba's environmental policy and EU Directive 2011/65/EU. The "LF" suffix in the part number explicitly denotes lead-free packaging. Full compliance documentation, including test reports and substance declarations, is available through Toshiba's official product portal.
Can TC7W241FUTE12LF replace TC7W240FUTE12LF in a design?
No - TC7W241FUTE12LF is a non-inverting buffer, while TC7W240FUTE12LF is an inverting buffer. Their truth tables differ: TC7W241FUTE12LF passes A1/A2 unchanged to Y1/Y2 when enabled, whereas TC7W240FUTE12LF inverts them. Swapping them would invert critical control signals, causing functional failure unless logic inversion is compensated elsewhere in the design.
