Description
74125 IC Tri State Quad Bus
Buffer
DIP-14
The SN74LS125AN is a quad bus buffer designed with tri-state outputs that provide high-speed signal routing for digital systems. This device features four independent buffers, each with its own enable control, allowing for flexible management of data flow across the system. The tri-state output ensures that when the buffer is disabled, the output enters a high-impedance state, preventing it from interfering with other components in the bus.
Features:
Quad Bus Buffers with 3-State Outputs
Separate Control for each Channel
High-Impedance Output State
Standard TTL Switching Voltages
