DESCRIPTION

V_SS

The UT54ACS245 and the UT54ACTS245 are non-inverting

octal bus transceivers designed for asynchronous two-way com-

munication between data buses. The control function imple-

mentation minimizes external timing requirements.

20-Lead Flatpack

V_DD

The devices allow data transmission from the A bus to the B bus

or from the B bus to the A bus depending upon the logic level

at the direction control (DIR) input. The enable input (G) dis-

ables the device so that the buses are effectively isolated.

The devices are characterized over full military temperature

range of -55 C to +125 C.
