Low-Voltage CMOS Octal Registered Transceiver With Dual Output and Clock Enables

With 5V-Tolerant Inputs and Outputs (3-State, Non-Inverting)

The MC74LCX2952 is a high performance, non–inverting octal registered transceiver operating from a 2.7 to 3.6V 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 5.5V allows MC74LCX2952 inputs to be safely driven from 5V devices. The MC74LCX2952 is suitable for memory address driving and all TTL level bus oriented transceiver applications.
