Quadruple Bus Transceiver
General Description
This four data line transceiver is designed for asynchro-
nous two-way communications between data buses. It can
be used to drive terminated lines down to 133
.
Features
I
Two-way asynchronous communication between data
buses
I
PNP inputs reduce DC loading on bus line
I
Hysteresis at data inputs improves noise margin
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
