Nexperia USA Inc. 74LVC16240ADGG-Q1J

Overview

74LVC16240ADGG-Q1J from Nexperia is a 16-bit inverting buffer/line driver with 3-state outputs, 5 V tolerant I/O, and AEC-Q100 Grade 1 qualification for automotive use. 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 four independent output enables (1OE–4OE) for granular bus control in CAN/LIN interface modules and body control units.

For engineers reviewing the 74LVC16240ADGG-Q1J datasheet, 74LVC16240ADGG-Q1J pinout, 74LVC16240ADGG-Q1J application, or 74LVC16240ADGG-Q1J equivalent, key selection criteria include 5 V tolerance on all I/O pins, IOFF power-down protection, propagation delay ≤4.2 ns at 3.3 V, TSSOP48 thermal performance up to +125 °C ambient, and compliance with JEDEC JESD8-7A/5A/C standards.

Technical Context

This device implements a quad 4-bit inverting buffer architecture with independent active-low output enables per group (1OE–4OE), enabling selective 3-state control of four 4-bit output banks. Each bank inverts input signals (e.g., 1A0→1Y0) and supports bidirectional voltage translation between 1.2 V–3.6 V logic domains and 5 V systems.

The IOFF circuit ensures zero backflow current during partial power-down, critical for hot-swap and fail-safe operation in automotive domain controllers. Input clamping diodes and ESD protection (HBM >2000 V, CDM >1000 V) are integrated to meet harsh vehicle environment requirements without external components.

FAQ

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

When VCC = 0 V, the absolute maximum input voltage is +5.5 V per the datasheet limiting values table. The IOFF circuitry actively disables outputs and blocks reverse current flow, allowing safe application of 5 V signals to inputs during power-down states without damage or leakage exceeding ±10 μA.

Can this device drive a 50 pF capacitive load at 25 MHz?

Yes. With CPD = 11.4 pF and tpd ≤4.2 ns at VCC = 3.3 V, the device meets timing margins for 25 MHz operation driving 50 pF loads. Dynamic power calculation (PD = CPD × VCC² × fi × N) confirms <1.5 mW total dissipation, well within the 500 mW TSSOP48 limit at +125 °C ambient.

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

The flow-through architecture places complementary input/output pairs (e.g., 1A0 at pin 47 and 1Y0 at pin 2) on opposite edges of the TSSOP48 package. This allows straight-line routing with minimal layer transitions, reduces crosstalk between adjacent bits, and simplifies length matching for timing-critical parallel buses in automotive domain controllers.

Is there a recommended decoupling strategy for this device?

Use one 100 nF X7R ceramic capacitor per VCC pin (pins 7, 18, 31, 42), placed within 3 mm of each pin and connected directly to the nearest GND pin (e.g., pin 4 for VCC at pin 7). This configuration leverages the eight GND pins to form low-inductance return paths, suppressing ground bounce below 50 mV during simultaneous 16-bit switching events.
