1-14 CARD AND MANUAL
IDENTIFICATION
1-15 Hewlett-Packard 1/0 cards are identified by a two-
part serial number, for example, 19124-00840. This number
appears on a label affixed to the component side of the circuit
card. The breakdown of the serial number is explained using
the example number 19124-00840.
1912A-00840
Add 60 to this This is a five-digit
number to get number which is
the year. So, assigned sequentially

dicates the last date when a significant design change was
made
Table 1-1. Specifications and Supplemental Data
DIGITAL OUTPUTS:
TTL Logic Leveis - As shipped, all data line outputs are
jumper connected as positive true with 5. 1KQ pull-up resistors
connected to +5 V. In the high state, the outputs will source
up to 200. A at 3.8 V minimum. In the low state, the outputs
will sink up to 100 mA at 0.5 V maximum.
Open Collector - Any or ali output lines can be converted to
open-collector outputs by clipping out the associated 5.1kQ
resistor. The maximum collector voltage is 40 volts, and the
maximum sink current is 100 mA.
External Bias - Up to 30 Y maximum when using card pull-up
resistors.
CARD'S EXTERNAL I/O CONTROL LINES:
EXTERNAL ENABLE (input Signal} - When high, the output
data lines are enabled; when low, the output data lines are
low.
High = 2.0 V to 5.0 V. (or no connection)
Low = 0.0 V to 0.5 V. (or short to ground)
EXTERNAL TRIGGER (Input Signal) - Edge sensitive
signal used to transfer data from first to second rank
storage and to the card's output terminals.
TRIGGER POLARITY SELECT (Input Signal) - Defines
the true state of the EXTERNAL TRIGGER. High. means
High true EXTERNAL TRIGGER.
High = 2.0 V to 5.0 V (or no connection).
Low = 0.0 V to 0.5 V {or short to ground).
The driving signal must sink 1 mA in the low state,
GATE {Output Signal) - Output data is valid when gate goes
high.
High = 3.7 V while sourcing 200p A.
Low = 0.5 V while sinking 7 mA.
GATE (Output signal) - Same as GATE, but logic sense is
inverted (low true).
FLAG (Input Signal) - indicates that data has been accepted.
High = 2.0 V to 5.0 V (or open circuit).
Low = 0.0 V to 0.5 V (or contact closure to ground).
The driving signa! must sink 1 mA in the low state.
FLAG POLARITY SELECT {input Signal) - Defines the true
state of the FLAG signal.
High means High true FLAG. Low means Low true FLAG.
High = 2.0 V to 5.0 V (or not connection).
Low = 0.0 V to 0.5 V {or short to ground).
The driving signal must sink 1 mA in the fow state.
END OF PROCESS (Output Signal) - This signal goes high to
indicate that the card has completed its operation. After a
minimum of 2us it is reset low by the Multiprogrammer.
High = 3.7 V while sourcing 2002ms.
Low = 0.5 V while sinking 7 mA.
BUSY (Output Signal) - This signal goes high while the card is
busy performing its operation.
High = 3.7 V while sourcing 200p A.
Low = 0.5 V while sinking 7 mA.
TEMPERATURE RANGE:
From 0°C to +70°C operating in the mainframe {allows
15°C internal rise in temperature when operating in the
mainframe at up to +55°C ambient); From — 40°C to
+80°C storage.
CARD DIMENSIONS:
Card - 299,.722mm x 132.08mm (11.8 in. x 5.2 in.).
Card Breadboard Area - 98.4mm x 60.3mm (3-7/8 in x 2-3/8
in.).
+5 V Current Requirement: 750 mA. Max.
