PIN NAME DESCRIPTION
1-4 DIO 1 thru DIO 4 Data Input/Output. Bits are HIGH with the data is logical 0 and LOW when the data is
logical 1.
5 EOI End Or Identify. A low-true state indicates that the last byte of a multibyte message
has been placed on the line.
6DAVData Valid. A low-true state indicates that the talker has (1) sensed that NRFD is
LOW, (2) placed a byte of data on the bus, and (3) waited an appropriate length of
time for the data to settle.
7 NRFD Not Ready For Data. A high-true state indicates that valid data has not yet been
accepted by a listener.
8 NDAC Not Data Accepted. A high-false state indicates that the current data byte has been
accepted for internal processing by a listener.
9 IFC Interface Clear. A low-true state places all bus instruments in a known state—such
as, unaddressed to talk, unaddressed to listen, and service request idle.
10 SRQ Service Request. A low-true state indicates that a bus instrument needs service from
the controller.
11 ATN Attention. A low-true state enables the controller to respond to both it’s own
listen/talk address and to appropriate interface messages — such as, device clear
and serial poll.
12 Shield Chassis ground.
13-16 DIO 5 thru DIO 8 Data Input/Output. Bits are high with the data is logical 0 and LOW when the data is
logical 1.
