Product details

Overview

74LVC240APW,112 from NXP Semiconductors is an octal buffer/line driver with 3-state outputs, designed for address/data bus interface in 3.3 V digital systems. It features ±24 mA output drive, 3.3 V supply operation, and operates from -40 °C to +125 °C. Used in industrial control backplanes and memory I/O expansion circuits.

For engineers reviewing the 74LVC240APW,112 datasheet, 74LVC240APW,112 pinout, 74LVC240APW,112 application, or 74LVC240APW,112 equivalent, key selection criteria include output drive strength, 3-state timing control, bus hold capability, and compatibility with LVTTL and CMOS logic families at 3.3 V.

Technical Context

This device integrates eight non-inverting buffers with dual active-low output-enable inputs (1OE, 2OE), enabling independent control of two groups of four drivers. Each output supports 3-state operation with high-impedance off-state and rail-to-rail voltage swing under 3.3 V supply.

It complies with JEDEC standard JESD8-12 for 3.3 V logic and meets AEC-Q100 Grade 1 reliability requirements. Input thresholds are compatible with both 3.3 V CMOS and 5 V tolerant LVTTL signals, supporting mixed-voltage system interfacing.

Equivalent & Alternatives

The following parts are listed as comparable options for similar octal 3-state buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC240APWR	TSSOP16 package same; identical electrical specs but TI's version lacks AEC-Q100 qualification	Not suitable for automotive Grade 1 environments requiring temperature validation	Select 74LVC240APW,112 where extended temperature and automotive qualification are mandatory
74LVC240AD,118	SO16 package; same logic function and voltage specs, but 1.27 mm pitch increases PCB area by 40%	Preferred for through-hole prototyping or legacy SOIC-based designs	Choose 74LVC240APW,112 for space-constrained SMT layouts requiring fine-pitch routing

Compared with SN74LVC240APWR and 74LVC240AD,118, the 74LVC240APW,112 offers AEC-Q100 Grade 1 qualification and TSSOP16 footprint - critical for automotive and high-density industrial PCBs where thermal reliability and layout efficiency are design constraints.

FAQ

Is the 74LVC240APW,112 pin-compatible with older 74HC240 devices?

No. While both are octal 3-state buffers, the 74LVC240APW,112 uses LVC logic thresholds and 3.3 V supply optimization, whereas 74HC240 operates at 2–6 V with HC thresholds. Pinout matches TSSOP16 layout, but voltage domain and timing parameters differ significantly.

Does this device support hot-swap insertion into a live 3.3 V bus?

Yes. Its 5 V tolerant inputs and over-voltage protected structure allow safe insertion into a powered bus. The 3-state outputs remain high-impedance until OE is asserted, preventing bus contention during plug-in.

What is the maximum capacitive load this device can drive reliably?

It drives up to 15 pF per output with guaranteed timing (6.7 ns t_PD) at 3.3 V. For loads exceeding 15 pF, propagation delay increases linearly; derating is required beyond 30 pF to maintain timing margins in synchronous systems.

Can both output-enable inputs (1OE and 2OE) be tied together for single-control operation?

Yes. Connecting 1OE and 2OE simplifies control logic and enables simultaneous enable/disable of all eight outputs. No timing penalty occurs, as both enable paths share identical internal delay characteristics per NXP's characterization data.
