Frequently Asked Questions
What logic family does the SN74AHCT32D belong to, and what supply voltage does it support?
The SN74AHCT32D belongs to the AHCT (Advanced High-Speed CMOS with TTL-compatible inputs) logic family. It operates from a 5V supply while accepting inputs from both 3.3V and 5V logic systems, making it ideal for mixed-voltage designs in embedded and digital systems.
How many OR gates are in the SN74AHCT32D and what is the maximum output current?
The SN74AHCT32D contains four independent 2-input OR gates in a single package. The maximum output low current (I_OL) is 8mA, which is sufficient for driving standard TTL and CMOS loads in most digital circuit applications.
What package does the SN74AHCT32D come in and what are typical applications?
The SN74AHCT32D is available in a 14-pin SOIC (Small Outline Integrated Circuit) package. Typical applications include logic signal combining, interrupt logic, bus arbitration circuits, microcontroller interface designs, and any digital system requiring 2-input OR logic operations.
Is there a pin-compatible alternative or substitute for the SN74AHCT32D?
Yes, pin-compatible alternatives include the SN74HCT32D (HCT logic family) and SN74AHC32D (AHC logic family without TTL-input compatibility). All three share the same 14-pin SOIC pinout and quadruple 2-input OR gate function, but differ in switching speed, input thresholds, and drive capability.
