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

high-impedance state to the bus so the output will

’125 and ’LS125A devices’ outputs are disabled  
when G is high. The ’126 and ’LS126A devices’  
outputs are disabled when G is low.
