Overview
The SN74AHC32PW is a commercial-grade quadruple 2-input positive-OR gate manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 5.5V and features low power consumption with a maximum ICC of 10µA. The device provides ±8mA output drive capability at 5V and includes latch-up performance exceeding 250mA per JESD 17. It is housed in a 14-pin TSSOP package and supports an operating free-air temperature range from -40°C to +125°C.
Feature Summary
- Implements the Boolean function Y = A + B using four independent 2-input OR gates
- Features balanced CMOS push-pull outputs capable of sinking and sourcing similar currents
- Includes standard CMOS inputs requiring termination to VCC or GND when unused
Applications
- Enable or disable a digital signal
- Controlling an indicator LED
- Translation between communication modules and system controllers
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific ordering suffix matches the required package type and rating. Review the latest datasheet revision history for any updates to electrical characteristics or thermal metrics before finalizing procurement specifications.
Selection Notes
Select this component for applications requiring multiple independent OR logic functions in a compact surface-mount form factor. Ensure the design accommodates the specified input transition rates to prevent excessive power consumption. Verify that the load capacitance remains within recommended limits to maintain switching performance specifications.
Part Context
This part belongs to the SNx4AHC32 family, which encompasses both military (SN54) and commercial (SN74) ratings. The PW suffix specifically denotes the 14-pin Thin Shrink Small Outline Package (TSSOP). Other available packages in this family include SOIC, SSOP, and VQFN variants, offering flexibility for different board space constraints.
Replacement Considerations
Direct replacements include other SN74AHC32 variants such as SN74AHC32DR (SOIC), SN74AHC32DBR (SSOP), and SN74AHC32DGVR (TVSOP). These alternatives share identical logical functionality but differ in physical package dimensions and pin configurations.
