combined with the SN75160B octal bus
transceiver, the SN75164B provides the complete
ATN + EOI ATN Logical or EOI Logic
16-wire interface for the IEEE-488 bus.
The SN75164B features eight driver-receiver

pairs connected in a front-to-back configuration to
form input/output (I/O) ports at both the bus and terminal sides. All outputs are disabled (at a high-impedance
state) during VCC power-up and power-down transitions for glitch-free operation. The direction of data flow
through these driver-receiver pairs is determined by the DC, TE, and SC enable signals. The SN75164B is
identical to the SN75162B with the addition of an OR gate to help simplify board layouts in several popular
applications. The ATN and EOI signals are ORed to pin 21, which is a standard totem-pole output.
