SN74LS125N

The SN74LS125N is a quadruple bus buffer IC manufactured by Texas Instruments. It utilizes the LS technology family and offers 3-state outputs, providing flexibility in bus interfacing.

This component operates with a supply voltage ranging from 4.75 V to 5.25 V and has an operating temperature range of 0°C to 70°C. Key electrical characteristics include an IOL of 24 mA maximum and an IOH of -2.6 mA maximum. The device features input clamp diodes and high-speed operation with a typical propagation delay (tpd) between 10-50 ns.

The SN74LS125N is available in a PDIP-14 package, designed for through-hole mounting. Its 3-state outputs can be disabled, presenting a high-impedance state to the bus, which prevents it from acting as a significant load or driver when not in use. This makes it suitable for applications requiring efficient bus management and signal buffering.

This buffer is designed for applications where driving heavily loaded bus lines is necessary. The additional drive capability at high logic levels, combined with the high-impedance state when disabled, ensures reliable bus communication.
