Octal Bus Transceiver with 3-STATE Outputs
General Description
This advanced Schottky device contains 8 pairs of
3-STATE logic elements configured as octal bus transceiv-
ers. These circuits are designed for use in memory, micro-
processor systems and in asynchronous bidirectional data
buses. Two way communication between buses is con-
trolled by the (DIR) input. Data transmits either from the A
bus to the B bus or from the B bus to the A bus. Both the
driver and receiver outputs can be disabled via the (G)
enable input which causes outputs to enter the high imped-
ance mode so that the buses are effectively isolated.
Features
s Advanced oxide-isolated, ion-implanted Schottky
TTL process
s Non-inverting logic output
s 3-STATE outputs independently controlled on
A and B buses
s Low output impedance to drive terminated transmission
lines to 133
s Switching response specified into 500/50 pF
s Specified to interface with CMOS at VOH = VCC 2V
s PNP inputs reduce input loading
s Switching specifications guaranteed over full
temperature and VCC range
