Nexperia USA Inc. 74LVT241D,118

Overview

74LVT241D,118 from Nexperia is a 3.3 V BiCMOS octal 3-state buffer/line driver with dual independent output enables (1OE active LOW, 2OE active HIGH), ±64 mA/–32 mA drive capability, bus-hold inputs, and operation from –40 °C to +85 °C. It interfaces 3.3 V logic to 5 V buses and is used in high-speed data bus driving applications such as memory address/data buffering in industrial control backplanes.

For engineers reviewing the 74LVT241D,118 datasheet, 74LVT241D,118 pinout, 74LVT241D,118 application, or 74LVT241D,118 equivalent, key selection criteria include its dual 3-state control architecture, TTL-compatible input thresholds, bus-hold functionality eliminating external pull-ups, and SO20 package thermal performance for dense PCB layouts.

Technical Context

This device implements two independent 4-bit 3-state buffer groups (1A0–1A3 → 1Y0–1Y3; 2A0–2A3 → 2Y0–2Y3), each controlled by separate enable signals. Its BiCMOS process delivers low static current (0.12 mA typical with outputs disabled) while supporting fast propagation delays: 2.8 ns typical (1An→1Yn) at 3.3 V.

The bus-hold circuitry maintains valid logic states on unused inputs without external resistors, with IBHL = 75–150 μA (LOW) and IBHH = –150 to –75 μA (HIGH) at 3.0 V. Input clamping voltage is –0.9 V typical, and ESD protection meets HBM >2000 V and CDM >1000 V per JS-001/JS-002.

FAQ

What is the maximum capacitive load the 74LVT241D,118 can drive while maintaining specified timing?

The datasheet specifies dynamic characteristics up to 50 pF load capacitance (CL = 50 pF) with RL = 500 Ω in the test circuit. At this load, t_PLH/t_PHL remains ≤3.8 ns at 3.3 V. Driving >50 pF increases propagation delay nonlinearly and may violate setup/hold margins in high-frequency buses; external series termination or buffer staging is recommended beyond this limit.

Can 74LVT241D,118 safely interface with 5 V microcontrollers without level shifters?

Yes - its inputs tolerate 0–5.5 V and outputs drive 5 V buses directly. The VIH minimum is 2.0 V, compatible with 5 V TTL logic highs, and VOH reaches 2.2 V (min) at –32 mA, sufficient to meet 5 V TTL VIH thresholds. No level-shifting circuitry is needed for bidirectional 3.3 V ↔ 5 V interfacing.

How does the bus-hold function behave when an input is left unconnected?

Bus-hold actively maintains the last-valid logic state using feedback circuitry. For a floating 1A0 input, IBHL (75–150 μA) pulls it LOW if previously LOW; IBHH (–150 to –75 μA) pulls it HIGH if previously HIGH. This prevents metastability and EMI from floating nodes, eliminating the need for external 10 kΩ pull-up/down resistors on unused inputs.

Is the SO20 package (SOT163-1) lead-free and RoHS compliant?

Yes - Nexperia confirms the 74LVT241D,118 in SO20 packaging meets RoHS Directive 2011/65/EU and REACH SVHC requirements. The terminations are 100% matte tin, and the package contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE above threshold limits.
