Hot-selling and scarce MC74LCX245DTR2 Low-Voltage CMOS Octal Transceiver TSSOP20 spot stock

Product Descriptions

The MC74LCX245 is a high performance, non−inverting octal transceiver operating from a 1.65 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.AVI specification of 5.5 V allows MC74LCX245 inputs to be safely driven from 5 V devices if _V CC is less than 5.0 V. TheMC74LCX245 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 at V CC = 3.0 V.  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.
