Nexperia USA Inc. 74LVC32ABQ,115

Overview

74LVC32ABQ,115 from Nexperia is a quad 2-input OR gate logic IC in DHVQFN14 (SOT762-1) package, operating from 1.2 V to 3.6 V supply, with overvoltage-tolerant inputs up to 5.5 V and Schmitt-trigger inputs for noise immunity. It supports mixed-voltage interfacing between 3.3 V and 5 V systems and is rated for -40 °C to +125 °C operation. Typical propagation delay is 2.2 ns at VCC = 3.3 V.

For engineers reviewing the 74LVC32ABQ,115 datasheet, 74LVC32ABQ,115 pinout, 74LVC32ABQ,115 application, or 74LVC32ABQ,115 equivalent, this device serves as a robust, low-power translation-capable logic gate for industrial control I/O expansion, FPGA/CPLD glue logic, and mixed-supply bus arbitration where input rise/fall time tolerance and rail-to-rail compatibility are critical.

Technical Context

The 74LVC32ABQ implements four independent OR gates with Schmitt-trigger inputs, enabling reliable operation with slow or noisy digital signals. Each gate accepts inputs referenced to GND and delivers CMOS-compatible outputs referenced to VCC.

Its overvoltage-tolerant inputs (up to 5.5 V) allow direct connection to 5 V logic while powered from 1.2–3.6 V supplies, eliminating level-shifter requirements. The DHVQFN14 package provides thermal enhancement and space efficiency for high-density PCB layouts.

FAQ

Is the 74LVC32ABQ,115 pin-compatible with other 74LVC32A variants?

Yes - all 74LVC32A variants share identical logic functionality and pin assignments (1A–4Y, GND, VCC), but physical pinouts differ across packages (SO14, TSSOP14, DHVQFN14, DHXQFN14). The DHVQFN14 pin numbering follows SOT762-1: Pin 1 = 1A, Pin 2 = 1B, Pin 3 = 1Y, Pin 4 = 2A, Pin 5 = 2B, Pin 6 = 2Y, Pin 7 = GND, Pin 8 = 3Y, Pin 9 = 3A, Pin 10 = 3B, Pin 11 = 4Y, Pin 12 = 4A, Pin 13 = 4B, Pin 14 = VCC.

Can the 74LVC32ABQ,115 operate with a 5 V supply?

No - the absolute maximum VCC is +6.5 V, but the recommended operating range is strictly 1.2 V to 3.6 V per JEDEC JESD8 compliance. Operating above 3.6 V violates specification and risks parametric failure or reduced reliability; however, inputs tolerate up to 5.5 V regardless of VCC, enabling safe 5 V signal reception at 3.3 V supply.

What is the role of the exposed thermal pad in the DHVQFN14 package?

The exposed pad (Pin 1 index area) in SOT762-1 has no electrical function and is not internally connected. Nexperia specifies it may remain floating or be soldered to GND for improved thermal conduction - but if connected, it must not introduce ground loops or violate system grounding schemes. No electrical requirement exists to solder it.

Does the 74LVC32ABQ,115 support partial power-down or I/O isolation?

No - the 74LVC32A family lacks Ioff (power-off protection) or IOZ (three-state) features. When VCC = 0 V, inputs and outputs are undefined and may draw excessive current or cause bus contention. For hot-swap or partial-power-down applications, a device with Ioff specification (e.g., 74LVC2G32) must be selected instead.
