The series circuits are dual versions of the popular CA5160 series. They are designed and guaranteed to operate in microprocessor or logic systems that use +5V supplies. Gate-protected P-Channel MOSFET (PMOS) transistors are used in the input circuit to provide very-high-input impedance, very-low-input current, and exceptional speed performance. The use of PMOS field-effect transistors in the input stage results in common-mode input-voltage capability down to 0.5V below the negative-supply terminal, an important attribute in single-supply applications. A complementary-symmetry MOS (CMOS) transistor-pair, capable of swinging the output voltage to within 10mV of either supply-voltage terminal (at very high values of load impedance), is employed as the output circuit. The Series circuits operate at supply voltages ranging from 4.5V to 16V, or ±2.25V to ±8V when using split supplies. The, A have guaranteed specifications for 5V operation over the full military temperature range of -55 o C to 125 o C. Ordering Information PART NUMBER (BRAND) TEMP. RANGE ( o C) PKG. NO.
