MC74LCX245
Low-Voltage CMOS Octal Transceiver
With 5 V−Tolerant Inputs and Outputs (3−State, Non−Inverting)
The MC74LCX245 is a high performance, non−inverting octal transceiver operating from a 2.0 to 5.5 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 MC74LCX245 inputs to be safely driven from 5 V devices if VCC is less than 5.0 V. The MC74LCX245 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.
