74ABT125
Quad Buffer with 3-STATE Outputs
Features
■ Non-inverting buffers
■ Output sink capability of 64mA, source capability of
32mA
■ Guaranteed latchup protection
■ High impedance glitch free bus loading during entire
power up and power down cycle
■ Nondestructive hot insertion capability
■ Disable time less than enable time to avoid bus
contention
General Description
The ABT125 contains four independent non-inverting
buffers with 3-STATE outputs.
