Quadruple Bus Buffers With 3-State Outputs - SN74LS125A
Datasheet
 

Description

These bus buffers feature three-state outputs that, when enabled, have the low impedance characteristics of a TTL output with additional drive capability at high logic levels to permit driving heavily loaded bus lines without external pullup resistors. When disabled, both output transistors are turned off, presenting a high-impedance state to the bus so the output will act neither as a significant load nor as a driver. The ’125 and ’LS125A devices’ outputs are disabled when G\ is high. The ’126 and ’LS126A devices’ outputs are disabled when G is low.

Features

  • Quad Bus Buffers
  • 3-State Outputs
  • Separate Control for Each Channel

The SN54125, SN54126, SN74125, SN74126, and SN54LS126A are obsolete and are no longer supplied.
