Octal Bus Buffer/Line Driver
SEMICONDUCTOR TECHNICAL DATA#! # $
$ " %" "" #"#"!
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 3–state buffer, and has two active–low
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 = 3.6ns (Typ) at VCC = 5V Low Power Dissipation: ICC = 4μA (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 = 0.9V (Max) Pin and Function Compatible with Other Standard Logic Families Latchup Performance Exceeds 300mA ESD Performance: HBM > 2000V; Machine Model > 200V Chip Complexity: 120 FETs or 30 Equivalent Gates
