DM74ALS5245/74ALS5245-1
Octal 3-STATE Transceiver
General Description
This octal bus transceiver is designed for asynchronous
two-way communication between data buses. The inputs in-
clude hysteresis which provides improved noise rejection.
Data is transmitted either from the A bus to the B bus or from
the B bus to the A bus depending on the logic level of the di-
rection control (DIR) input. The device can be disabled via
the enable input (G ) which causes the outputs to enter the
high impedance mode so the buses are effectively isolated.
The ALS5245-1 features the same performance as the
ALS5245 with the addition of increased current drive capa-
bility to meet the requirements of various bus architectures.
The recommended maximum IOL is increased to 48 mA.
Features

n Advanced oxide-isolated, ion implanted Schottky TTL
process
n Switching specification guaranteed over the full
temperature and VCC range
n PNP inputs to reduce input loading
n Maximum IOL is increased to 48 mA for ALS5245-1
