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 V

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.
