description  
The SN75ALS164 eight-channel general-purpose interface bus transceiver is a monolithic, high-speed,  
advanced low-power Schottky device designed to meet the requirements of IEEE Standard 488-1978. Each  
transceiver is designed to provide the bus-management and data-transfer signals between operating units of  
a multiple-controller instrumentation system. When combined with the SN75ALS160 octal bus transceiver, the  
SN75ALS164 provides the complete 16-wire interface for the IEEE 488 bus.  
The SN75ALS164 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 the high-impedance state)  
during V  
power-up and power-down transitions for glitch-free operation. The direction of data flow through  
CC  
these driver-receiver pairs is determined by the DC, TE, and SC enable signals. The SN75ALS164 is identical  
to the SN75ALS162 with the addition of an OR gate to help simplify board layouts in several popular  
applications. The ATN and EOI signals are ORed to provide the ATN + EOI output, which is a standard  
totem-pole output.  
The driver outputs (GPIB I/O ports) feature active bus-terminating resistor circuits designed to provide a high  
impedance to the bus when supply voltage V  
is 0. The drivers are designed to handle loads up to 48 mA of  
CC  
sink current. Each receiver features pnp transistor inputs for high input impedance and hysteresis of 400 mV  
minimum for increased noise immunity. All receivers have 3-state outputs that present a high impedance to the  
terminal when disabled.  
The SN75ALS164 is characterized for operation from 0°C to 70°C.
