Frequently Asked Questions
What is the SN74HC125NE4 and what does it do?
The SN74HC125NE4 is a 4-channel non-inverting buffer and line driver IC from Texas Instruments with 3-state outputs. It belongs to the HC/UH CMOS logic family and features enable-low control pins, allowing each output to be placed in a high-impedance state. It supports up to 150pF load capacitance and 6mA output current, making it suitable for bus driving applications.
What are the key electrical specifications of the SN74HC125NE4?
Key specifications include: 4 independent channels with non-inverting logic, 3-state outputs controlled by active-low enable pins, maximum output low current (I_OL) of 6mA, load capacitance (CL) of 150pF, HC CMOS logic family compatibility, and JESD-609 lead-free (e4) compliance. The device is housed in a 14-pin DIP package (R-PDIP-T14).
What are typical applications for the SN74HC125NE4?
Typical applications include digital bus buffering, data bus expansion for microcontrollers, 3-state bus arbitration, signal isolation between logic domains, memory interface circuits, and communication system line driving. The 3-state output feature makes it especially useful in shared bus architectures where multiple drivers must be connected to the same bus lines.
What package does the SN74HC125NE4 come in and are there SMD alternatives?
The SN74HC125NE4 comes in a 14-pin Dual-In-Line Package (DIP/PDIP), which is well-suited for through-hole assembly and prototyping. For surface-mount applications, Texas Instruments also offers equivalent devices in SOIC (SN74HC125D), SSOP (SN74HC125PW), and TSSOP packages. The 'NE4' suffix indicates the DIP package with lead-free (RoHS) compliance.
How can I purchase the SN74HC125NE4 and what is the price?
The SN74HC125NE4 is available from authorized distributors worldwide starting at approximately $0.532 per unit. It is stocked globally with worldwide shipping options. You can request a quote directly through FindMyChip to get competitive pricing for both small quantities and bulk orders.
