Overview
The SN74AHC32PWR is a quadruple 2-input positive-OR gate from the Texas Instruments AHC logic family. It operates within a supply voltage range of 2V to 5.5V and provides ±8mA output drive at 5V. The device features low power consumption with a maximum ICC of 10µA and latch-up performance exceeding 250mA per JESD 17. It is housed in a 14-pin TSSOP package and supports an operating temperature range of -40°C to +125°C.
Feature Summary
- Performs Boolean OR function Y = A + B for four independent channels
- Standard CMOS inputs require termination to prevent undefined states
- Balanced CMOS push-pull outputs capable of sinking and sourcing similar currents
Applications
- Enable or disable digital signals
- Controlling indicator LEDs
- Translation between communication modules and system controllers
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current orderable addendum, as packaging quantities and carrier types vary by variant. Confirm that the component meets RoHS compliance requirements for your assembly process. Ensure the selected package matches the thermal and footprint specifications required by the design.
Selection Notes
Select this component when a wide supply voltage range from 2V to 5.5V is required for OR logic operations. It is suitable for designs needing balanced push-pull outputs and standard CMOS input compatibility. Consider the TSSOP-14 package constraints regarding thermal resistance and pin pitch during layout planning.
Part Context
This part belongs to the SNx4AHC32 series, which includes military-grade (SN54) and commercial-grade (SN74) variants. The 'PWR' suffix specifically denotes the TSSOP-14 surface-mount package configuration. Other available packages for this logic function include SOIC, SSOP, and VQFN options.
Replacement Considerations
Direct replacements include other SN74AHC32 variants such as SN74AHC32DR (SOIC) or SN74AHC32DBR (SSOP). Verify pinout compatibility and ensure the alternative package meets the same thermal and electrical specifications.
