Product details
Overview
74LVT32D,112 from NXP Semiconductors (formerly Philips) is a 3.3 V quad 2-input OR gate logic IC in a 14-pin SO package. It delivers propagation delays of 2.6 ns (tPLH) and 3.2 ns (tPHL) at VCC = 3.3 V with CL = 50 pF, supports –40 °C to +85 °C operation, and drives up to 32 mA low-level output current - used in high-speed bus interface and level-shifting logic circuits.
For engineers reviewing the 74LVT32D,112 datasheet, 74LVT32D,112 pinout, 74LVT32D,112 application, or 74LVT32D,112 equivalent, key selection criteria include its LVT-family 3.3 V CMOS compatibility, guaranteed AC performance across industrial temperature range, input/output voltage tolerance up to 5.5 V, and SO14 footprint for legacy board compatibility.
Technical Context
The 74LVT32D,112 implements four independent 2-input OR gates using advanced BiCMOS LVT (Low-Voltage TTL) technology, enabling TTL-level input thresholds (VIL = 0.8 V, VIH = 2.0 V) while operating from a 3.3 V supply. Its outputs are fully 5 V-tolerant, supporting mixed-voltage system interfacing without external level shifters.
It features rail-to-rail output swing, low input capacitance (3 pF), and quiescent supply current as low as 0.02 mA (ICCH) with all outputs high. The device meets JEDEC JESD8-5 and JESD8-B standards for 3.3 V logic interfaces and is designed for use in hot-swap-capable backplane and control-plane applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar OR gate logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC32APWR | Lower VCC range (1.65–3.6 V); higher max IOL (24 mA); not 5 V-tolerant | Requires strict 3.3 V supply regulation; unsuitable for 5 V input interfacing | Select when only 3.3 V-only systems are targeted and cost is prioritized over voltage flexibility |
| 74ALVC32D,112 | Same SO14 package; lower propagation delay (2.1 ns typ); identical 5 V-tolerance and VCC range | Higher speed enables tighter timing margins in high-frequency control loops | Select when sub-2.5 ns delay is required and NXP's ALVC family qualification is acceptable |
Compared with 74LVT32D,112, SN74LVC32APWR offers lower cost but sacrifices 5 V input tolerance and industrial temperature margin, while 74ALVC32D,112 provides faster timing with identical voltage and package compatibility - making it a true performance upgrade path within the same footprint.

FAQ
What is the maximum operating supply voltage for the 74LVT32D,112?
The 74LVT32D,112 has an absolute maximum VCC rating of +4.6 V, but its recommended operating range is strictly 2.7 V to 3.6 V. Operation outside this window may cause timing violations or increased power dissipation. For reliable long-term function, maintain VCC within 3.3 V ±0.3 V, as specified in the AC characteristics table of the 74LVT32D,112 datasheet.
Does the 74LVT32D,112 support 5 V input signals?
Yes, the 74LVT32D,112 accepts input voltages up to 5.5 V while powered from 3.3 V, per its VI specification. This 5 V-tolerance eliminates need for external level shifters when interfacing with legacy 5 V logic. The 74LVT32D,112 achieves this via internal clamp structures, confirmed in the Absolute Maximum Ratings and DC Electrical Characteristics sections of its official product data sheet.
What is the pinout configuration of the 74LVT32D,112?
The 74LVT32D,112 uses a standard 14-pin SO package (SOT108-1) with GND on pin 7 and VCC on pin 14. Inputs occupy pins 1,2,4,5,9,10,12,13 (A0/B0 through A3/B3); outputs are on pins 3,6,8,11 (Y0 through Y3). This layout matches JEDEC-standard 74-series logic pinouts, ensuring mechanical and functional compatibility with other SO14 logic devices including the 74LVT32D,112.
Can the 74LVT32D,112 drive a 50 pF load at full speed?
Yes, the 74LVT32D,112's AC characteristics are explicitly characterized at CL = 50 pF with RL = 500 Ω, delivering tPLH = 2.6 ns and tPHL = 3.2 ns at VCC = 3.3 V. This load condition reflects typical PCB trace + input capacitance in industrial control boards. The 74LVT32D,112 maintains these specs across –40 °C to +85 °C, confirming suitability for real-world 50 pF loading scenarios.
Is the 74LVT32D,112 RoHS compliant?
Yes, the 74LVT32D,112 is RoHS compliant and lead-free, consistent with NXP's transition to green packaging starting in the early 2000s. The SOT108-1 package uses matte tin (Sn) termination, and the device meets EU Directive 2011/65/EU requirements. Compliance documentation for the 74LVT32D,112 is available via NXP's official product change notifications and material declarations portal.
