Overview
The 74ALVC32PW,112 is a quad 2-input OR gate manufactured by Nexperia. It operates within a supply voltage range of 1.65 V to 3.6 V and features Schmitt trigger inputs for tolerance of slow rise and fall times. The device includes IOFF circuitry for partial power-down applications, preventing backflow current. It complies with JEDEC standards JESD8-7, JESD8-5, and JESD8C/JESD36. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). Latch-up performance exceeds 250 mA per JESD78 Class II.A. The component is specified for ambient temperatures from -40 °C to +125 °C.
Feature Summary
- Schmitt trigger action on all inputs provides tolerance for slow signal transitions.
- IOFF circuitry enables partial power-down mode operation to prevent damaging backflow currents.
- Inputs are overvoltage tolerant up to 3.6 V, allowing direct interface with TTL levels.
Applications
- Partial power-down applications requiring backflow current prevention
- Interfaces with TTL logic levels
- Systems requiring tolerance for slow rise and fall times
Procurement Notes
Verify the specific ordering suffix '112' corresponds to the TSSOP14 package (SOT402-1) as defined in the official datasheet. Confirm that the manufacturer designation aligns with Nexperia B.V., as NXP Semiconductors has undergone corporate restructuring. Ensure the requested revision matches the latest product data sheet version to guarantee accurate electrical specifications and package dimensions.
Selection Notes
Select this component when a quad 2-input OR gate is required with Schmitt trigger inputs for noise immunity against slow signals. It is suitable for designs needing direct interfacing with TTL levels and overvoltage tolerant inputs up to 3.6 V. The inclusion of IOFF circuitry makes it appropriate for partial power-down scenarios. Verify that the TSSOP14 package fits the board layout constraints and that the operating temperature range meets the application requirements.
Part Context
The 74ALVC32PW,112 belongs to the 74ALVC series of low-voltage CMOS logic devices. This series is characterized by high speed and low power consumption. The PW suffix indicates the TSSOP14 plastic thin shrink small outline package. The device functions as a standard quad 2-input OR gate but adds robustness through Schmitt triggers and partial power-down capabilities, distinguishing it from basic logic gates in the same family.
Replacement Considerations
Public confirmed substitute part numbers include 74ALVC32D,118 and SN74ALVC32NSR.
FAQ
What is the function of the IOFF circuitry in the 74ALVC32?
The IOFF circuitry disables the outputs when the device is powered down, preventing potentially damaging backflow current through the device.
How does the 74ALVC32 handle slow input signals?
Schmitt trigger action on all inputs makes the device tolerant of slow rise and fall times.
