Product details
Overview
SN74LVC1G332DBVR from Texas Instruments is a single 3-input positive-OR gate logic IC in SOT-23 (DBV) package, performing Y = A + B + C Boolean function with 4.5 ns max propagation delay at 3.3 V, ±24-mA output drive, and 10-µA max ICC. It supports 1.65–5.5 V supply operation, accepts 5.5-V inputs, and enables level translation down to VCC - used in power management sequencing, bus arbitration, and system enable logic.
For engineers reviewing the SN74LVC1G332DBVR datasheet, SN74LVC1G332DBVR pinout, SN74LVC1G332DBVR application, or SN74LVC1G332DBVR equivalent, key selection criteria include Ioff-enabled live insertion support, 125°C operating temperature, NanoStar™ packaging for board space savings, and verified 3.3-V/5-V mixed-signal interface compatibility.
Technical Context
The SN74LVC1G332DBVR implements a noninverting 3-input OR gate using LVC CMOS process technology, with full rail-to-rail input voltage tolerance up to 5.5 V independent of VCC. Its Ioff circuitry actively disables outputs during partial power-down, preventing back-drive current flow when VCC = 0 V.
Propagation delay is characterized across VCC = 1.8 V to 5 V and load capacitance CL = 15 pF to 50 pF, with worst-case tpd = 6.2 ns at 3.3 V/CL = 50 pF/TA = 125°C. Input thresholds scale with VCC per JEDEC JESD8-5, supporting robust noise margins across supply voltages.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G332DCKR | SC70-6 package (2.0 mm × 1.25 mm); identical electrical specs and pinout mapping | Smaller footprint but lower thermal mass; less suitable for high-reliability thermal cycling environments | Select when board area is constrained and thermal stress is minimal |
| SN74LVC1G332DRYR | SON-6 (DRY) package (1.45 mm × 1.0 mm); same logic function and Ioff capability | No leads - requires precise stencil design and reflow profile; not hand-solderable | Choose for ultra-dense layouts where automated assembly is guaranteed |

FAQ
What is the maximum propagation delay of the SN74LVC1G332DBVR at 3.3 V?
The SN74LVC1G332DBVR has a maximum propagation delay (tpd) of 4.5 ns at VCC = 3.3 V, CL = 15 pF, and TA = 25°C. At elevated temperature (125°C) and higher load (CL = 50 pF), worst-case tpd increases to 6.2 ns - still sufficient for sub-100-MHz control logic timing budgets. This value is measured from any input (A, B, or C) to output Y under specified conditions.
Does the SN74LVC1G332DBVR support 5-V input signals when powered from a 3.3-V supply?
Yes, the SN74LVC1G332DBVR supports input voltages up to 5.5 V regardless of VCC level - including when VCC = 3.3 V. This 5-V tolerant input structure allows seamless interfacing with legacy 5-V peripherals, sensors, or microcontrollers without level-shifting circuitry. The input clamp diodes and internal design ensure safe operation within absolute maximum ratings.
Can the SN74LVC1G332DBVR be used in partial-power-down systems?
Yes, the SN74LVC1G332DBVR incorporates Ioff circuitry that disables outputs when VCC = 0 V, preventing damaging back-current flow through the device. This feature enables safe live insertion, hot-swap capability, and reliable operation in systems where subsystems power up/down independently - such as modular industrial controllers or multi-rail power supplies.
What is the operating temperature range for the SN74LVC1G332DBVR?
The SN74LVC1G332DBVR is rated for continuous operation from –40°C to +125°C ambient temperature. This extended range qualifies it for under-hood automotive applications, industrial motor drives, and outdoor telecom equipment. Performance parameters including propagation delay, output drive, and input thresholds are fully specified across this range per JEDEC JESD78 Class II latch-up testing.
Is the SN74LVC1G332DBVR pin-compatible with other 3-input OR gates in TI's LVC family?
Yes, the SN74LVC1G332DBVR shares identical pinout (A-GND-B-Y-C-VCC) and logic function with all package variants of the SN74LVC1G332, including DCKR (SC70), DRYR (SON), and DSFR (X2SON). All variants implement Y = A + B + C with matching electrical characteristics, enabling drop-in replacement across packages without PCB redesign - provided thermal and mechanical constraints are met.
