Nexperia USA Inc. 74LVC16241ADGG,112

Overview

74LVC16241ADGG,112 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 ambient. Used in high-density data bus isolation and level translation in industrial control backplanes.

For engineers reviewing the 74LVC16241ADGG,112 datasheet, 74LVC16241ADGG,112 pinout, 74LVC16241ADGG,112 application, or 74LVC16241ADGG,112 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., from mechanical switches or RC networks). The 48-pin TSSOP package features 8 ground and 4 VCC pins to minimize simultaneous switching noise and ground bounce in high-speed parallel interfaces.

FAQ

Can 74LVC16241ADGG,112 be used with a 1.2 V supply and 5 V inputs simultaneously?

Yes. The device is fully specified for operation at VCC = 1.2 V while accepting input voltages up to 5.5 V. Input clamping diodes safely shunt excess voltage to VCC or GND, and the 5 V tolerant structure prevents damage or functional failure. Static characteristics (VIH/VIL) and timing (tpd, ten) are guaranteed across this condition per Table 5 and Table 7.

What is the difference between 1OE/4OE and 2OE/3OE logic polarity?

1OE and 4OE are active-LOW inputs: outputs go high-impedance when these pins are driven HIGH. 2OE and 3OE are active-HIGH: outputs go high-impedance when driven LOW. This dual-polarity OE architecture allows direct connection to complementary control signals (e.g., /WR and RD) without external inverters, simplifying FPGA or microcontroller GPIO usage.

Does the TSSOP48 package require thermal vias or special layout practices?

While the SOT362-1 package has no exposed thermal pad, its 8 GND and 4 VCC pins provide inherent thermal and electrical benefits. For continuous operation above 70 °C ambient, place ≥6 thermal vias (0.3 mm diameter, 0.6 mm pitch) under the GND pads and connect them to an internal ground plane. Avoid routing high-speed traces under the device body to prevent coupling into sensitive Schmitt inputs.

How does the Schmitt-trigger input improve system reliability?

Schmitt-trigger inputs provide ~0.3 V hysteresis at 3.3 V VCC, meaning VIH ≈ 2.0 V and VIL ≈ 1.7 V. This prevents multiple transitions on slowly rising/falling signals (e.g., from long cables or RC-filtered switches), eliminating contact bounce artifacts and false triggering in control logic - especially critical in industrial HMI and sensor interface applications.
