74LVC245A
Low-Voltage CMOS Octal
Transceiver
With 5 V−Tolerant Inputs and Outputs
(3−State, Non−Inverting)
The 74LVC245A is a high performance, non−inverting octal
transceiver operating from a 1.2 to 3.6 V 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 5.5 V allows 74LVC245A inputs to
be safely driven from 5 V devices if VCC is less than 5.0 V. The
74LVC245A is suitable for memory address driving and all TTL level
bus oriented transceiver applications.
Current drive capability is 24 mA 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.
