The MC74VHC540 is an advanced high speed CMOS inverting octal bus
buffer fabricated with silicon gate CMOS technology. It achieves high speed
operation similar to equivalent Bipolar Schottky TTL while maintaining
CMOS low power dissipation.
The MC74VHC540 features inputs and outputs on opposite sides of the
package and two AND–ed active–low output enables. When either OE1 or
OE2 are high, the terminal outputs are in the high impedance state.
The internal circuit is composed of three stages, including a buffer output
which provides high noise immunity and stable output. The inputs tolerate
voltages up to 7V, allowing the interface of 5V systems to 3V systems.
High Speed: tPD = 3.7ns (Typ) at VCC = 5V
Low Power Dissipation: ICC = 4
