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
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:
• “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
(R1 resistors are common to leads 14, 16, or 20)
(R2 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.
