Nexperia USA Inc. 74LVT241PW,118

Overview

74LVT241PW,118 from Nexperia is a 3.3 V octal 3-state buffer/line driver in TSSOP20 package, featuring 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 with 5 V buses and is used for bidirectional bus driving in industrial control backplanes and memory address/data buffering.

For engineers reviewing the 74LVT241PW,118 datasheet, 74LVT241PW,118 pinout, 74LVT241PW,118 application, or 74LVT241PW,118 equivalent, key selection criteria include dual 3-state control timing, bus-hold input retention without external resistors, TTL-compatible I/O levels, and verified 3.3 V supply operation with 5 V tolerant inputs.

Technical Context

This BiCMOS device implements two independent 4-bit 3-state buffers: Group 1 (1A0–1A3 → 1Y0–1Y3, controlled by 1OE) and Group 2 (2A0–2A3 → 2Y0–2Y3, controlled by 2OE). Each group supports simultaneous enable/disable with distinct polarity-1OE is active LOW while 2OE is active HIGH-enabling flexible bus arbitration and hot-swap control.

It delivers TTL-level switching with VIH ≥ 2.0 V and VIL ≤ 0.8 V at 3.3 V supply, maintains 5 V input tolerance per JESD8-A, and uses internal bus-hold circuitry (IBHL = 75–150 μA, IBHH = –150 to –75 μA) to retain logic states on unused inputs without external pull-ups.

FAQ

What is the maximum input voltage the 74LVT241PW,118 can tolerate?

The device supports input voltages from –0.5 V to +5.5 V regardless of VCC level, enabling direct connection to 5 V TTL outputs without level shifters. This is verified per JESD8-A and confirmed in Table 4 (Limiting Values) and Table 5 (Recommended Operating Conditions) of the datasheet.

Does the 74LVT241PW,118 require external pull-up resistors on unused inputs?

No. The device integrates bus-hold circuitry on all data inputs (1A0–1A3, 2A0–2A3), providing ±75 μA to ±150 μA holding current to retain the last valid logic state. This eliminates the need for external pull-up or pull-down resistors in unconnected or sparsely used bus configurations.

How does the dual output enable (1OE and 2OE) function in practice?

1OE (pin 1) is active LOW and controls outputs 1Y0–1Y3; 2OE (pin 19) is active HIGH and controls outputs 2Y0–2Y3. This polarity asymmetry allows independent, non-conflicting bus arbitration - for example, holding Group 1 active while tri-stating Group 2 during read/write phase transitions in memory-mapped I/O.

Is the 74LVT241PW,118 suitable for hot-swap applications?

Yes. It complies with JEDEC JESD63 for live insertion/extraction, features power-up 3-state behavior, and includes bus-hold to prevent floating inputs during partial connection. These characteristics make it appropriate for modular backplanes and field-replaceable units where boards are inserted under power.
