The MC74LCX2245 is a high performance, non–inverting octal
transceiver operating from a 2.7 to 3.6V supply. High impedance TTL
compatible inputs significantly reduce current loading to input drivers
while TTL compatible outputs offer improved switching noise
performance. A VI specification of 5.5V allows MC74LCX2245 inputs to
be safely driven from 5V devices. The MC74LCX2245 is designed to
reduce output overshoot and undershoot and is suitable for memory
address driving and all TTL level bus oriented transceiver applications;
especially those requiring the very quiet outputs.
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 5V T olerant — Interface Capability With 5V TTL Logic Supports Live Insertion and Withdrawal IOFF Specification Guarantees High Impedance When VCC = 0V LVTTL Compatible LVCMOS Compatible 12mA Balanced Output Sink and Source Capability Near Zero Static Supply Current in All Three Logic States (10μA)
Substantially Reduces System Power Requirements Latchup Performance Exceeds 500mA ESD Performance: Human Body Model >2000V; Machine Model >200V
