The CD74HC540E is an inverting octal Buffer/Line Driver with 3-state outputs and the capability to drive 15 LSTTL loads. The output enables (OE1\\) and (OE2\\) control the 3-state outputs. If either OE1\ or OE2\ is HIGH the outputs will be in the high impedance state. For data output OE1\ and OE2\ both must be LOW.
● Buffered inputs
● Bus line driving capability
● Balanced propagation delay and transition times
● Significant power reduction compared to LSTTL logic ICs
● High noise immunity - NIL = 30%, NIH = 30% of VCC at VCC = 5V
● Typical propagation delay = 9ns at VCC = 5V, CL = 15pF, TA = 25°C
● Standard outputs - 10 LSTTL loads
● Bus driver outputs - 15 LSTTL loads
