MC74VHC240
Octal Bus Buffer/Line Driver
Inverting with 3-State Outputs
The MC74VHC240 is an advanced high speed CMOS 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 MC74VHC240 is an inverting 3state buffer, and has two
activelow output enables. This device is designed to drive bus lines
or buffer memory address registers.
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 = 3.6 ns (Typ) at VCC = 5 V
Low Power Dissipation: ICC = 4 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 V to 5.5 V Operating Range
Low Noise: VOLP = 0.9 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: 120 FETs or 30 Equivalent Gates
These Devices are PbFree and are RoHS Compliant
