Frequently Asked Questions
What is the supply voltage range for the SN74AHC373N?
The SN74AHC373N operates over a supply voltage range of 2V to 5.5V, making it compatible with both 3.3V and 5V logic systems. This wide range is characteristic of the AHC (Advanced High-Speed CMOS) family from Texas Instruments.
How do the 3-state outputs work on the SN74AHC373N?
The SN74AHC373N features 3-state outputs controlled by an output enable (OE) pin. When OE is high, all outputs are placed in a high-impedance state, effectively disconnecting the device from the bus. This allows multiple devices to share the same data bus without contention.
What are typical applications for the SN74AHC373N?
The SN74AHC373N is commonly used in microprocessor address latching, memory interfacing, data bus expansion, and output port control. Its octal (8-bit) configuration and 3-state outputs make it ideal for embedded systems, industrial controllers, and digital communication designs.
What package does the SN74AHC373N come in and are there SMD alternatives?
The SN74AHC373N is packaged in a 20-pin DIP (Dual In-line Package), suitable for through-hole assembly. For surface-mount designs, Texas Instruments offers equivalent devices such as the SN74AHC373PWR (TSSOP) and SN74AHC373DWR (SOIC) with the same electrical characteristics.
