Commonly used in the following applications: Pin 1 • TTL input pull-down • Digital pulse squaring • TTL unused gate pull-up • High speed parallels pull-up • MOS/ROM pull-up/pull-down • Open collector pull-up • “Wired OR” pull-up • Power driven pull-up SOMC14 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: Pin 1 • Long-line Impedance balancing • LED current limiting • ECL output pull-down • TTL input pull-down • “Wired OR” pull-up • Power driven pull-up • Powergate pull-up • Line termination SOMC14 SOMC16 SOMC20 05 Schematic R1 R1 R2 R1 R2 R1 R2 R1 R2 R1 R1 R1 R1 R2 R2 R1 R2 R2 R1 R2 R1 R2 R1 R2 R2 R1 R2 R2 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.
