Nexperia USA Inc. 74LVC16241ADGG,512

Overview

74LVC16241ADGG,512 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 mixed-voltage interfacing (3.3 V logic driving 5 V buses), and is rated for -40 °C to +125 °C. Used in high-density data bus isolation and level translation in industrial control backplanes.

For engineers reviewing the 74LVC16241ADGG,512 datasheet, 74LVC16241ADGG,512 pinout, 74LVC16241ADGG,512 application, or 74LVC16241ADGG,512 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, 3-state enable timing asymmetry between active-low (1OE/4OE) and active-high (2OE/3OE) controls, and compliance with JEDEC JESD8-7A/5A/C standards.

Technical Context

This device implements four independent 4-bit non-inverting buffers, each with dedicated output-enable control (1OE–4OE). Two OE groups use opposite logic polarity: 1OE and 4OE are active-low; 2OE and 3OE are active-high - enabling flexible bus arbitration without external inverters.

Schmitt-trigger inputs provide hysteresis (typ. 0.3 V at 3.3 V), allowing reliable operation with slow-rising signals (e.g., RC-filtered microcontroller GPIOs). The 48-pin TSSOP package includes eight ground pins and four VCC pins to minimize simultaneous switching noise and ground bounce in high-speed parallel interfaces.

Compared with SN74LVC16244ADGGR, the 74LVC16241ADGG,512 adds Schmitt-trigger inputs and dual-polarity OE control - critical for robustness in electrically noisy environments. Versus 74ALVC16244DGG,118, it trades drive strength for extended temperature range and lower static power, making it preferable for automotive and harsh-environment deployments.

FAQ

What is the maximum input voltage the 74LVC16241ADGG,512 can safely withstand?

The device accepts input voltages from -0.5 V to +6.5 V absolute maximum, with functional operation guaranteed from 0 V to 5.5 V regardless of VCC level. This 5 V tolerance remains valid even when VCC = 1.2 V, enabling direct connection to 5 V buses without level-shifting circuitry.

How does the dual-polarity output enable (OE) architecture benefit system design?

1OE and 4OE are active-low, while 2OE and 3OE are active-high - allowing direct connection to complementary control signals (e.g., /CS and CS) without inverters. This simplifies bus arbitration logic in multi-master systems and reduces component count in FPGA- or MCU-based address decoders.

Can the 74LVC16241ADGG,512 be used in hot-swap applications where VCC may be absent?

Yes. When VCC = 0 V, the outputs enter high-impedance state with IOFF leakage ≤±20 μA at VI/VO = 5.5 V. This prevents back-powering of downstream circuits and avoids latch-up risk during live insertion of daughterboards or modular I/O cards.

What thermal derating applies to the TSSOP48 package above 109 °C ambient?

For the SOT362-1 (TSSOP48) package, total power dissipation (Ptot) derates linearly at 12.2 mW/K above 109 °C ambient. At 125 °C, Ptot is reduced to approximately 295 mW from the 500 mW rating at 109 °C - requiring careful thermal design in sealed enclosures or high-ambient automotive locations.
