3 Description
The SN74AHCT540-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.
