Octal Bus Buffer
Inverting
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 = 4A (Max) at TA = 25°C
High Noise Immunity: VNIH = VNIL = 28% VCC
Power Down Protection Provided on Inputs
Balanced Propagation Delays
Designed for 2V to 5.5V Operating Range
Low Noise: VOLP = 1.2V (Max)
Pin and Function Compatible with Other Standard Logic Families
Latchup Performance Exceeds 300mA
ESD Performance: HBM > 2000V; Machine Model > 200V
Chip Complexity: 124 FETs or 31 Equivalent Gates
