Nexperia USA Inc. 74LVC16241ADGG,518

Overview

74LVC16241ADGG,518 from Nexperia is a 16-bit non-inverting buffer/line driver with 3-state outputs, 5 V tolerant I/O, and Schmitt-trigger inputs for noise immunity. It operates from 1.2 V to 3.6 V supply, supports -40 °C to +125 °C ambient range, and enables mixed-voltage interfacing between 3.3 V and 5 V logic systems in industrial control backplanes.

For engineers reviewing the 74LVC16241ADGG,518 datasheet, 74LVC16241ADGG,518 pinout, 74LVC16241ADGG,518 application, or 74LVC16241ADGG,518 equivalent, key selection criteria include 5 V tolerance on all I/O pins, TSSOP48 package thermal performance, propagation delay ≤5.5 ns at 3.3 V, and quad-group 3-state enable architecture (1OE/4OE active-low, 2OE/3OE active-high).

Technical Context

This device implements four independent 4-bit non-inverting buffers, each with dedicated output-enable control-1OE/4OE (active LOW) and 2OE/3OE (active HIGH)-enabling flexible bus partitioning. All 16 inputs feature Schmitt-trigger action, ensuring robust operation with slow-rising signals down to 20 ns/V input transition rate at 1.65 V.

The TSSOP48 package includes eight ground pins (GND at pins 4, 10, 15, 21, 28, 34, 39, 45) and four VCC pins (7, 18, 31, 42), minimizing ground bounce and supporting high-speed switching with CPD = 15.0 pF at 3.3 V and dynamic power dissipation calculable via PD = CPD × VCC² × fi × N.

FAQ

Can 74LVC16241ADGG,518 drive 50 pF loads at 3.3 V while maintaining 5 ns propagation delay?

Yes. Per Table 7, tpd is 1.0–2.2 ns (typical) and ≤4.4 ns (max) at VCC = 3.0–3.6 V with CL = 50 pF and RL = 500 Ω, as verified in the test circuit of Figure 7. The device meets this timing under worst-case -40 °C to +125 °C conditions.

What happens if 5.5 V is applied to an output pin while VCC = 0 V?

The output structure supports up to 5.5 V in 3-state mode even with VCC = 0 V, per Table 4 (VO output voltage, 3-state). This enables safe hot-plug operation and prevents back-powering of the supply rail through output clamps.

Are all 16 inputs truly 5 V tolerant when VCC = 1.2 V?

Yes. Section 2 confirms "5 V tolerant inputs and outputs" across the full 1.2 V to 3.6 V VCC range. Table 4 specifies VI input voltage limits of -0.5 V to +6.5 V, and Table 5 confirms VI up to 5.5 V is allowed regardless of VCC value.

How does the dual-type output enable (active-HIGH and active-LOW) simplify bus arbitration?

The pairing of 1OE/4OE (active-LOW) with 2OE/3OE (active-HIGH) allows hierarchical enable control: one group can be enabled by default (e.g., 2OE tied HIGH), while others require explicit low-active strobes - reducing external logic for priority-based bus access in multi-master systems.
