3 Description

The SN74AHC540-Q1 contains eight inverters with

3-state outputs. The 540 function has the same

functionality as the 240 function and has a flowthrough

pinout. The active low output enable pins

(OE1 and OE2) control all eight channels, and are

configured so that both must be low for the outputs to

be active.
