NXP Semiconductors 74LVC32ADB,112

Overview

74LVC32ADB,112 from Nexperia is a quad 2-input OR gate logic IC in SO-14 package, operating at 1.65–3.6 V supply, with typical propagation delay of 3.1 ns at 3.3 V, ±24 mA output drive, and CMOS input compatibility. It serves as a basic combinational logic element in digital control subsystems of industrial I/O modules.

For engineers reviewing the 74LVC32ADB,112 datasheet, 74LVC32ADB,112 pinout, 74LVC32ADB,112 application, or 74LVC32ADB,112 equivalent, key selection criteria include supply voltage range, output drive strength, propagation delay consistency across temperature, and SO-14 thermal performance in dense PCB layouts.

Technical Context

This device implements four independent 2-input OR gates using silicon-gate CMOS technology. Each gate features rail-to-rail output swing, TTL-compatible input thresholds, and ESD protection exceeding 2 kV HBM.

It operates without internal latching or feedback paths, supporting purely combinational logic flow. Input hysteresis is absent, and output transition behavior follows standard CMOS voltage transfer characteristics under defined load and supply conditions.

FAQ

Is 74LVC32ADB,112 compatible with 5 V TTL inputs?

No. Its inputs are designed for LVTTL/CMOS levels: V_IH ≥ 1.7 V at V_CC = 3.3 V. Direct connection to 5 V TTL outputs risks overstressing inputs beyond absolute maximum rating of 4.6 V. A level-shifter or resistive divider is required for safe interfacing.

Does this device support hot insertion?

No. 74LVC32ADB,112 lacks hot-swap protection circuitry. Applying input signals before V_CC is stable may cause latch-up or excessive current draw. Power sequencing must ensure V_CC is established prior to asserting any inputs.

What is the maximum capacitive load this IC can drive reliably?

It is characterized up to 50 pF load capacitance per output, with guaranteed timing and drive strength. Driving >50 pF increases propagation delay nonlinearly and may cause overshoot/undershoot exceeding ±0.3 V; series termination or buffer staging is recommended for heavier loads.

Can unused inputs be left floating?

No. Floating inputs cause increased ICC, unpredictable output states, and potential oscillation due to intermediate voltage biasing. All unused inputs must be tied to V_CC or GND via direct connection or 10 kΩ resistor to ensure stable logic levels and minimize power consumption.
