NXP Semiconductors 74LVC241APW,118

Overview

74LVC241APW,118 from NXP Semiconductors is an octal non-inverting buffer/line driver with dual 3-state outputs, designed for bidirectional voltage translation between 3.3 V and 5 V logic domains. It features Schmitt-trigger inputs for noise immunity, 5.5 V-tolerant outputs in high-impedance state, and operates across 1.2 V to 3.6 V supply range. It is used in mixed-voltage bus interfacing in industrial control backplanes and FPGA I/O expansion.

For engineers reviewing the 74LVC241APW,118 datasheet, 74LVC241APW,118 pinout, 74LVC241APW,118 application, or 74LVC241APW,118 equivalent, key selection criteria include 5 V input/output tolerance, −40 °C to +125 °C operating range, TSSOP20 package compatibility, and dual independent output-enable control for flexible bus arbitration.

Technical Context

The 74LVC241APW,118 implements two independent 4-bit non-inverting buffers (Group 1: pins 1A0–1A3 → 1Y0–1Y3; Group 2: 2A0–2A3 → 2Y0–2Y3), each controlled by separate enable inputs (1OE active-low, 2OE active-high). Its Schmitt-trigger inputs accept slow-rising signals down to 20 ns/V transition rate at 3.6 V, enabling robust operation in noisy environments.

It supports true 5 V tolerance on all I/O pins - inputs accept up to 5.5 V regardless of VCC, and outputs withstand 5.5 V while disabled - allowing safe level-shifting without external components. The device complies with JEDEC standards JESD8-7A, JESD8-5A, and JESD8-C/JESD36 across its full 1.2 V–3.6 V supply range.

FAQ

What is the maximum supply voltage for the 74LVC241APW,118?

The absolute maximum supply voltage (VCC) for the 74LVC241APW,118 is +6.5 V, but the recommended operating range is strictly 1.2 V to 3.6 V per JEDEC specifications. Operating above 3.6 V risks violating logic thresholds and may cause undefined behavior or accelerated wear. The 74LVC241APW,118 maintains 5.5 V tolerance on I/O pins even at minimum VCC, enabling safe interfacing with higher-voltage peripherals.

Does the 74LVC241APW,118 support 1.8 V operation?

Yes, the 74LVC241APW,118 fully supports 1.8 V operation within the JESD8-7A standard (1.65 V to 1.95 V). At 1.8 V, it delivers guaranteed VIH = 1.17 V, VIL = 0.63 V, and tpd ≤ 14.1 ns across −40 °C to +85 °C. The 74LVC241APW,118 also meets all static and dynamic specifications at this voltage, including 5 V I/O tolerance and Schmitt-trigger input hysteresis.

How does the dual output-enable architecture of the 74LVC241APW,118 improve system design?

The 74LVC241APW,118 uses independent controls - 1OE (active-low) for Group 1 outputs and 2OE (active-high) for Group 2 - enabling asymmetric bus arbitration, partial enablement, and glitch-free state transitions. This allows one group to remain active while the other is tri-stated, reducing contention in multiplexed data paths. The 74LVC241APW,118 thus simplifies control logic in systems requiring staggered or conditional bus access without external gating.

Can the 74LVC241APW,118 be used as a level shifter between 3.3 V and 5 V logic?

Yes, the 74LVC241APW,118 is explicitly designed for bidirectional level translation: inputs accept 0–5.5 V regardless of VCC (1.2–3.6 V), and outputs tolerate 0–5.5 V in 3-state mode. When VCC = 3.3 V, it drives valid HIGH/LOW levels to 5 V loads and correctly interprets 5 V inputs as logic HIGH/LOW. The 74LVC241APW,118 requires no external resistors or direction-control signals, making it a passive, single-chip solution.

What is the ESD rating of the 74LVC241APW,118?

The 74LVC241APW,118 is rated for HBM > 2000 V, MM > 200 V, and CDM > 1000 V per JESD22-A114F, JESD22-A115B, and JESD22-C101E respectively. These ratings reflect factory-tested robustness against electrostatic discharge during handling and assembly. The 74LVC241APW,118 integrates on-die protection diodes and clamping structures, ensuring reliable operation in typical industrial assembly environments without requiring additional external ESD safeguards.
