DESCRIPTION
The 74ACT16244 is a low voltage CMOS 16-BIT
D-TYPE LATCH and 16 BIT BUS TRANSCEIVER
with 3-STATE output non inverting fabricated with
sub-micron silicon gate and double-layer metal
wiring C
2
MOS technology.
Both functions can be used as 16 bit or dual octal
devices, so the 16 bit transceiver can be used ad 8
bit bus buffer plus 8 bit transceiver, or only 16 bit
buffer in select direction.
LOGIC DIAGRAM
This device can be used to integrate in one chip
the internal logic component required to STV0701
to work ad P.O.D. interface in Digital TV
application. It is ideal for low power and high
speed 4.5 to 5.5. applications.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them ESD immunity and transient excess voltage.
