Frequently Asked Questions
What is the SN74AHCT125PW and what does it do?
The SN74AHCT125PW is a quad bus buffer gate with 3-state outputs from Texas Instruments. It provides four independent buffered channels, each controlled by an active-low output-enable pin, allowing it to drive or isolate bus lines in digital circuits operating between 2V and 5.5V.
What are the key electrical specifications of the SN74AHCT125PW?
The SN74AHCT125PW operates on a supply voltage range of 2V to 5.5V, features TTL-compatible inputs and CMOS-level outputs, has a typical propagation delay of approximately 8ns, and can source/sink up to 8mA output current per channel, making it suitable for both 3.3V and 5V systems.
What package does the SN74AHCT125PW come in?
The SN74AHCT125PW is housed in a 14-pin TSSOP (Thin Shrink Small Outline Package) — the 'PW' suffix indicates this package. Its compact footprint makes it well suited for space-constrained PCB designs in portable and high-density applications.
What are common applications for the SN74AHCT125PW?
Common applications include microcontroller GPIO expansion, level translation between 3.3V and 5V logic, data bus buffering in memory interfaces, and shared-bus architectures in industrial control, telecommunications, and consumer electronics products.
Are there pin-compatible alternatives to the SN74AHCT125PW?
Yes, pin-compatible alternatives include the 74HCT125 series from NXP and ON Semiconductor, the SN74HCT125PW (HCT logic, 5V only), and the SN74LVC125APW (3.3V LVC logic). Choose based on your required supply voltage and drive strength requirements.
