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

1.These values of VI are used to test DC electrical characteristics only. Functional test should use VIH ≥ 2.4V, VIL ≤ 0.5V.
2.Incident wave switching on transmission lines with impedances as low as 75Ω for commercial temperature range is guaranteed. Maximum test duration is 2ms, one output loaded at a time.
