74ACT16646
16-Bit Transceiver/Register with 3-STATE Outputs
General Description
The ACT16646 contains sixteen non-inverting bidirectional
registered bus transceivers providing multiplexed transmis-
sion of data directly from the input bus or from the internal
storage registers. Each byte has separate control inputs
which can be shorted together for full 16-bit operation. The
DIR inputs determine the direction of data flow through the
device. The CPAB and CPBA inputs load data into the reg-
isters on the LOW-to-HIGH transition.
Features
s Independent registers for A and B buses
s Multiplexed real-time and stored data transfers
s Separate control logic for each byte
s 16-bit version of the ACT646
s Outputs source/sink 24 mA
s TTL-compatible inputs
