The MC74LCX16646 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 MC74LCX16646 inputs to
be safely driven from 5V devices. The MC74LCX16646 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 (OEn) and Direction Control (DIRn) pins 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. The DIR determines which bus will receive data
when OE is active LOW. In the isolation mode (OE HIGH), A data may be
stored in the B register or B data may be stored in the A register. Only one
of the two buses, A or B, may be driven at one time.
