The LCX16652 contains sixteen non-inverting bidirectional bus transceivers with 3-STATE outputs providing multiplexed transmission of data directly from the input bus or from the internal registers. Data on the A or B bus will be clocked into the registers as the appropriate clock pin goes to the HIGH logic level. Output Enable pins (OEAB, OEBA
) are provided to control the transceiver function (see Functional Description).
The LCX16652 is designed for low-voltage (2.5V or 3.3V) VCC applications with capability of interfacing to a 5V signal environment.
The LCX16652 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation.
