Product details
Overview
TC7WT241FUTE12LF from Toshiba is a dual non-inverting 3-state bus buffer IC with active-high and active-low output enables, fabricated in silicon-gate CMOS technology. It delivers 13 ns typical propagation delay at 5 V, supports 4.5–5.5 V supply, operates from −40 °C to +85 °C, and drives up to 15 LSTTL loads - used in bidirectional data bus isolation for microcontroller peripheral interfaces.
For engineers reviewing the TC7WT241FUTE12LF datasheet, TC7WT241FUTE12LF pinout, TC7WT241FUTE12LF application, or TC7WT241FUTE12LF equivalent, key selection criteria include guaranteed 3-state off-leakage (±0.5 µA max), symmetrical ±6 mA output drive, TTL-compatible input thresholds, low ICC (2 µA max), and SM8 package compatibility with space-constrained PCB layouts.
Technical Context
This device implements two independent non-inverting buffers, each with separate enable control: one uses active-high G, the other active-low G. Both outputs enter high-impedance state when disabled, enabling bidirectional bus sharing without contention.
Designed for mixed-voltage system interfacing, it accepts TTL-level inputs (VIH ≥ 2.0 V, VIL ≤ 0.8 V) while operating from a single 5 V CMOS supply, eliminating level-shifter requirements in legacy LSTTL-to-CMOS bridging applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation delay | 13 ns typ. at VCC = 5 V, CL = 50 pF - ensures timing compliance in 20 MHz+ synchronous bus systems |
| Supply voltage range | 4.5–5.5 V - compatible with regulated 5 V rails and tolerates ±10% variation |
| Output drive | ±6 mA min. - sufficient to directly drive 15 LSTTL inputs without external buffering |
| 3-state off-leakage | ±0.5 µA max. at VCC = 5.5 V - prevents signal corruption during bus arbitration |
| Input threshold | VIH ≥ 2.0 V, VIL ≤ 0.8 V - guarantees reliable recognition of standard TTL logic levels |
| Operating temperature | −40 °C to +85 °C - qualified for industrial-grade embedded control environments |
| Quiescent current | 2 µA max. at Ta = 25 °C - enables ultra-low standby power in battery-backed systems |
Pinout & Package
Package: SM8 (Small Outline 8-pin, 2.9 mm × 2.8 mm, 0.65 mm pitch), surface-mount, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | G (active-low enable) | Controls Y1 output: Y1 = A1 when G = L; Y1 = Hi-Z when G = H |
| 2 | A1 | Non-inverting input for first buffer channel |
| 3 | Y1 | Non-inverting 3-state output for A1 |
| 4 | GND | Ground reference for all internal circuitry and I/O |
| 5 | Y2 | Non-inverting 3-state output for A2 |
| 6 | A2 | Non-inverting input for second buffer channel |
| 7 | G (active-high enable) | Controls Y2 output: Y2 = A2 when G = H; Y2 = Hi-Z when G = L |
| 8 | VCC | Positive supply terminal (4.5–5.5 V) |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable controls | One active-high and one active-low G input - simplifies interface with complementary control signals in bus arbitration logic |
| TTL-compatible input thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - eliminates need for external level translation when interfacing with legacy TTL peripherals |
| Low 3-state leakage | IOZ ≤ ±0.5 µA at VCC = 5.5 V - maintains bus integrity during extended Hi-Z periods in multi-master systems |
| Symmetrical output drive | |IOH| = IOL = 6 mA min. - ensures matched rise/fall times and predictable timing margins under load |
| ESD-protected inputs | Integrated protection against ±20 mA transient discharge - reduces need for external TVS components in board-level ESD design |
Applications
| Microcontroller Bus Expansion | Legacy Peripheral Interface |
|---|---|
Use Scenario: Expanding GPIO count on an 8-bit MCU by connecting parallel peripherals (e.g., LCD controller, keypad encoder) via shared data bus. IC Role / Device Role / Timing Role: Bidirectional bus buffer isolating MCU data lines from peripheral loading; enables time-multiplexed access using G controls. Use Value: Eliminates contention risk during bus handoff; 13 ns delay preserves timing margin for 20 MHz bus clocking. | Use Scenario: Interfacing modern 5 V CMOS microcontrollers with older TTL-based instrumentation modules (e.g., ADCs, DACs). IC Role / Device Role / Timing Role: Level-translating and load-driving buffer ensuring TTL output compatibility without external resistors or translators. Use Value: VIH/VIL thresholds match TTL specs; ±6 mA drive sustains signal integrity across 15 LSTTL loads. |
| Industrial Control Backplane | Test Equipment Signal Routing |
Use Scenario: Isolating sensor acquisition channels on a modular PLC backplane where multiple slots share a common data bus. IC Role / Device Role / Timing Role: 3-state bus driver enabling slot-selective communication; G inputs synchronized to address decode logic. Use Value: Low ICC (2 µA max) minimizes idle power across dozens of slots; −40 °C to +85 °C rating ensures field reliability. | Use Scenario: Reconfigurable signal path routing in automated test equipment (ATE), switching between DUT signal sources and measurement instruments. IC Role / Device Role / Timing Role: Direction-agnostic bus switch controlled by FPGA-generated enable signals for dynamic path assignment. Use Value: Independent active-high/low enables allow direct FPGA pin mapping without inverters; SM8 footprint saves board area in dense ATE modules. |
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 |
|---|---|---|---|
| SN74LVC2G241DCUR | 3.3 V only (1.65–3.6 V), smaller 8-pin VSSOP package, 3.7 ns tpd at 3.3 V | Not suitable for 5 V systems; requires level shifters if interfacing with TTL or 5 V logic | Select when migrating to 3.3 V domains and higher speed is critical |
| 74LCX241MTCX | 5 V tolerant inputs, 3.3 V supply (2.7–3.6 V), 5.5 ns tpd at 3.3 V, higher ICC (10 µA typ.) | Requires 3.3 V rail; 5 V-tolerant inputs allow mixed-voltage connection but no native 5 V operation | Choose for 3.3 V systems needing 5 V input compatibility and lower propagation delay |
Compared with SN74LVC2G241DCUR and 74LCX241MTCX, the TC7WT241FUTE12LF uniquely supports native 5 V operation with TTL-compatible thresholds and industrial temperature range - making it the only drop-in solution for legacy 5 V bus architectures requiring zero level-shifting overhead.

FAQ
What is the maximum supply voltage rating for TC7WT241FUTE12LF?
The absolute maximum supply voltage for TC7WT241FUTE12LF is 7 V, but the recommended operating range is strictly 4.5 V to 5.5 V. Exceeding 5.5 V during normal operation risks violating DC electrical characteristics and may accelerate parametric drift over time. The 7 V rating applies only to short-duration transients under controlled test conditions, not continuous use.
Does TC7WT241FUTE12LF support true bidirectional data flow?
No - TC7WT241FUTE12LF is a dual unidirectional non-inverting buffer with independent 3-state controls. Each channel (A1→Y1 and A2→Y2) flows in one direction only. True bidirectional operation requires external control logic coordinating the two enables; the device itself does not auto-sense direction or include internal direction control circuitry.
What is the meaning of "SM8" in the TC7WT241FUTE12LF package designation?
SM8 denotes Toshiba's standardized 8-pin small-outline package: 2.9 mm × 2.8 mm body size, 0.65 mm lead pitch, gull-wing leads, and JEDEC MO-178 compliant footprint. It is distinct from SOIC-8 (3.9 mm wide) and TSSOP-8 (3.0 mm wide), offering higher board density for compact industrial PCBs.
Can TC7WT241FUTE12LF be used with a 3.3 V supply?
No - TC7WT241FUTE12LF is specified only for 4.5–5.5 V operation. At 3.3 V, VIH and VIL thresholds become non-compliant (VIH min = 2.0 V requires ≥4 V VCC per datasheet), and output drive degrades below specification. For 3.3 V systems, consider SN74LVC2G241 or 74LCX241 instead.
Is TC7WT241FUTE12LF RoHS-compliant and lead-free?
Yes - TC7WT241FUTE12LF is RoHS-compliant and manufactured with lead-free terminations per J-STD-609 Category 1. The "LF" suffix in the part number explicitly indicates lead-free packaging, and the device meets EU Directive 2011/65/EU requirements without exemptions.
