SEMICONDUCTOR TECHNICAL DATA
Low-Voltage Quiet CMOS
Octal Buffer
(3-State, Non-Inverting)
The MC74LVQ244 is a high performance, non–inverting octal buffer
operating from a 2.7 to 3.6V supply. The MC74LVQ244 is suitable for
memory address driving and all TTL level bus oriented transceiver
applications.
Current drive capability is 12mA at the outputs. The Output Enable
(OE) input, when HIGH, disables the output by placing them in a HIGH Z
condition.
• Designed for 2.7 to 3.6V VCC Operation – Ideal for Low Power/Low
Noise Applications
• Guaranteed Simultaneous Switching Noise Level and Dynamic
Threshold Performance
• Guaranteed Skew Specifications
• Guaranteed Incident Wave Switching into 75Ω
• Low Static Supply Current (10µA) Substantially Reduces System Power
Requirements
• Latchup Performance Exceeds 500mA
• ESD Performance: Human Body Model >2000V
Pinout: 20–Lead (Top View)
