MC74VHC540
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 ANDed activelow 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 7.0 V, allowing the interface of 5.0 V
systems to 3.0 V systems.
Features
High Speed: tPD = 3.7 ns (Typ) at VCC = 5.0 V
Low Power Dissipation: ICC = 4.0 μA (Max) at TA = 25°C
High Noise Immunity: VNIH = VNIL = 28% VCC
Power Down Protection Provided on Inputs
Balanced Propagation Delays
Designed for 2.0 V to 5.5 V Operating Range
Low Noise: VOLP = 1.2 V (Max)
Pin and Function Compatible with Other Standard Logic Families
Latchup Performance Exceeds 300 mA
ESD Performance: HBM > 2000 V; Machine Model > 200 V
Chip Complexity: 124 FETs or 31 Equivalent Gates
These Devices are PbFree and are RoHS Compliant
