Product details

Overview

74LVC16240ADL,112 from Nexperia is a 16-bit inverting buffer/line driver with 3-state outputs, 5 V-tolerant I/O, and four independent output-enable inputs (1OE–4OE). It operates from 1.2 V to 3.6 V supply, supports mixed-voltage interfacing (3.3 V logic driving 5 V buses), and features IOFF partial power-down protection. It is used in address/data bus buffering for industrial controllers and FPGA I/O expansion.

For engineers reviewing the 74LVC16240ADL,112 datasheet, 74LVC16240ADL,112 pinout, 74LVC16240ADL,112 application, or 74LVC16240ADL,112 equivalent, key selection criteria include 5 V tolerance on all I/O pins, propagation delay ≤4.2 ns at 3.3 V, 3-state enable/disable timing, TSSOP48 thermal performance, and compatibility with JEDEC JESD8-7A/5A/C standards.

Technical Context

The device implements four independent 4-bit inverting buffers, each controlled by its own active-low output-enable input (1OE–4OE). Each buffer section drives four complementary inverted outputs (e.g., 1Y0–1Y3 from 1A0–1A3) into high-impedance when disabled.

IOFF circuitry actively disables outputs during power-down, blocking backflow current even when up to 5.5 V is applied to outputs while VCC = 0 V. Input thresholds comply with multiple JEDEC voltage-tier standards (JESD8-7A, -5A, -C), enabling interoperability across 1.65 V–3.6 V supply domains.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	1.2 V to 3.6 V - enables operation in ultra-low-power and standard 3.3 V systems
Input Voltage Range	0 V to 5.5 V - allows direct connection to 5 V TTL/CMOS without level shifters

Equivalent & Alternatives

The following parts are listed as comparable options for similar 16-bit inverting buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC16240ADGGR	Same logic function, identical pinout, but TI package (TSSOP48, DGGR) has different thermal pad design and moisture sensitivity level (MSL 3 vs MSL 1)	Requires requalification for humidity-sensitive SMT processes; no IOFF spec provided in TI datasheet	Select if TI supply chain alignment is required; verify IOFF behavior and MSL handling in production environment
74ALVC16240PW,118	Nexperia ALVC variant - higher speed (tpd ≤3.2 ns at 3.3 V) but narrower VCC range (2.3–3.6 V) and no 1.2 V support	Not suitable for ultra-low-voltage battery-powered designs; lacks 1.2 V operation and JESD8-7A compliance	Choose only when maximum speed is prioritized over voltage flexibility and mixed-supply interoperability

Compared with SN74LVC16240ADGGR and 74ALVC16240PW,118, the 74LVC16240ADL,112 uniquely combines 1.2 V operation, full JEDEC tier compliance, and guaranteed IOFF - making it the only option qualified for both low-power portable and robust industrial hot-swap systems.

FAQ

What is the maximum allowable input voltage when VCC = 0 V?

When VCC = 0 V, the absolute maximum input voltage is −0.5 V to +6.5 V per Table 4 (Limiting Values), and the IOFF circuit ensures outputs remain high-impedance with leakage ≤±20 μA at VI = 5.5 V. This enables safe hot-plug operation in backplane systems.

Can 74LVC16240ADL,112 drive 50 Ω transmission lines directly?

No - the device is not designed as a line driver for impedance-matched transmission lines. Its 24 mA output drive is optimized for CMOS/TTL fanout and short PCB traces. For 50 Ω lines, external series termination or dedicated line drivers are required to prevent reflections and overshoot.

How does the MULTIBYTE flow-through pinout improve PCB layout?

The pinout groups related inputs and outputs (e.g., 1A0/1Y0 adjacent) and distributes power/ground pins evenly - reducing trace length mismatch, minimizing crosstalk, and simplifying layer stack routing. This lowers ground bounce by up to 40% compared to traditional staggered layouts, as confirmed in Nexperia's layout guidelines.

Is 74LVC16240ADL,112 qualified for automotive applications?

No - this part is not AEC-Q100 qualified and is specified only for industrial temperature range (−40 °C to +125 °C). Nexperia explicitly states non-automotive qualification in Section 14 of the datasheet; automotive use requires formal qualification and separate reliability testing not performed on this variant.
