SEMICONDUCTOR TECHNICAL DATA
Low-Voltage Quiet CMOS
Octal Transceiver
(3-State, Non-Inverting)
The MC74LVQ245 is a high performance, non–inverting octal
transceiver operating from a 2.7 to 3.6V supply. The MC74LVQ245 is
suitable for memory address driving and all TTL level bus oriented
transceiver applications.
Current drive capability is 12mA at both A and B ports. The
Transmit/Receive (T/R) input determines the direction of data flow
through the bi–directional transceiver. Transmit (active–HIGH) enables
data from A ports to B ports; Receive (active–LOW) enables data from B
to A ports. The Output Enable input, when HIGH, disables both A and B
ports 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
