Advance Information
Low-Voltage CMOS 16-Bit Transceiver/Registered Transceiver With Dual Enable
With 5V-Tolerant Inputs and Outputs (3-State, Non-Inverting)
The MC74LCX16652 is a high performance, non-inverting 16-bit transceiver/registered transceiver operating from a 2.7 to 3.6V supply. The device is byte controlled. Each byte has separate control inputs which can be tied together for full 16-bit operation. 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 MC74LCX16652 inputs to be safely driven from 5V devices. The MC74LCX16652 is suitable for memory address driving and all TTL level bus oriented transceiver applications. Data on the A or B bus will be clocked into the registers as the appropriate clock pin goes from a LOW-to-HIGH logic level. Output Enable pins (OEBAn, OEABn) are provided to control the transceiver outputs. In the transceiver mode, data present at the high impedance port may be stored in either the A or the B register or in both. The select controls (SBAn, SABn) can multiplex stored and real-time (transparent mode) data. In the isolation mode (both outputs disabled), A data may be stored in the B register or B data may be stored in the A register. When in the real-time mode, it is possible to store data without using the internal registers by simultaneously enabling OEAB and OEBA. In this configuration, each output reinforces its input (data retention is not guaranteed in this mode).
