Low-Voltage/Low-Power Octal Bus Transceiver with Bus-hold
transceiver. By a low power consumption circuit, power
consumption has been reduced when a bus terminal is disable state
(OE=High).
DIR input. The OE input can be used to disable the device so that the
busses are effectively isolated.

Floating of A-bus and B-bus are permitted.(When OE=H)
Gate IC for control(TC7MP01FK) of DIR and OE terminal are prepared.
3.6V tolerant function provided on A-bus terminal, DIR and OE terminal.
Note 1: At the time bus terminal is enable state, please do not give a signal from the outside.
Note 2: When mounting VQON package, the type of recommended flux is RA or RMA.
But, bus of a B bus side at floating state is maintained in an
Low power current consumption : By a new input circuit, power consumption in OE=H is reduced largely.
Ultra-small package
Bus hold circuit is built in only the B bus side.(Only in OE=H, a former state is maintained.)
