Rochester Electronics Logic - Buffers, Drivers, Receivers, Transceivers MC74LCX245DTG

The MC74LCX245DTG is a low-voltage CMOS octal transceiver designed for operation with supply voltages ranging from 1.65 V to 5.5 V. It features 5 V tolerant inputs and outputs, making it compatible with 5 V TTL logic, which is beneficial for interfacing with various digital systems. The device supports live insertion and withdrawal, ensuring flexibility in system design. This transceiver has a current drive capability of 24 mA at both A and B ports when powered at 3.0 V, and it operates with near-zero static supply current in all three logic states, significantly reducing overall power consumption. The device includes a Transmit/Receive (T/R) input to control data flow direction and an Output Enable (OE) input to disable both ports, placing them in a high-impedance state. The MC74LCX245DTG is AEC-Q100 qualified, making it suitable for automotive applications, and it is available in a TSSOP-20 package. It also exhibits robust ESD performance, withstanding voltages greater than 2000 V according to the Human Body Model. This combination of features makes the MC74LCX245DTG a reliable choice for memory address driving and TTL level bus-oriented applications.
