The MC74LVQ646 is a high performance, non–inverting octal
transceiver/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. The MC74LVQ646 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 (OE) and DIR 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 (SBA,
SAB) can multiplex stored and real–time (transparent mode) data. The
direction control (DIR) determines which bus will receive data when the
enable 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.
