Product Overview
74LVC245: Octal Transceiver, CMOS, Low Voltage
For complete documentation, see the data sheet
Product Description
The 74LVC245A is a high performance, non-inverting octal transceiver operating from a 1.2 to 5.5V 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 74LVC245A inputs to be safely driven from 5V devices. The 74LVC245A is suitable
for memory address driving and all TTL level bus oriented transceiver applications.
Current drive capability is 24mA at both A and B ports. The Transmit/Receive (T/Rbar) 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.
