CIRCUIT APPLICATIONS
01 Schematic
13, 15, or 19 resistors with one pin common
The SOMCxx01 circuit provides a choice of 13, 15, or 19 nominally equal resistors, each
connected between a common lead (14, 16, or 20) and a discrete PC board pin.
Commonly used in the following applications:
• MOS/ROM pull-up/pull-down
• Open collector pull-up
• “Wired OR” pull-up
• Power driven pull-up
• TTL input pull-down
• Digital pulse squaring
• TTL unused gate pull-up
• High speed parallels pull-up

SOMC16
SOMC20
03 Schematic
7, 8, or 10 isolated resistors
The SOMCxx03 circuit provides a choice of 7, 8, or 10 nominally equal resistors with each
resistor isolated from all others and wired directly across. Commonly used in the following
applications:
SOMC14
SOMC16
SOMC20
Pin 1
• “Wired OR” pull-up
• Power driven pull-up
• Powergate pull-up
• Line termination
• Long-line Impedance balancing
• LED current limiting
• ECL output pull-down
• TTL input pull-down
05 Schematic
TTL dual-line terminator; pulse squaring, 12, 14, or 18 pairs of resistors
(R
1
resistors are common to leads 14, 16, or 20)
(R
2
resistors are common to leads 7, 8, or 10)
The SOMCxx05 circuit contains 12, 14, or 18 pairs of resistors. Each pair is connected
between ground and a common line. The junctions of these resistor pairs are connected
to the input leads.
The 05 circuits are designed for TTL dual-line termination and pulse squaring.
