HD74HC540/HD74HC541
Octal Buffers/Line Drivers (with 3-state outputs)
Description
The HD74HC540 is an inverting buffer and the HD74HC541 is a non-inverting buffer. The 3-state control
gate operates as a two-input NOR such that if either G
1
or G
2
are high, all eight outputs are in the high-
impedance state.
