PGH758A

The PGH758A has the following features including (1)When the supply voltage is lower than minimum operating voltage, the operation of output transistor is indefinite. In the case of Nch open drain type, the output voltage is equal to pull-up voltage.;(2)The output voltage becomes GND level.;(3)When the supply voltage is higher than released voltage (Point B), VrefVDDRb/(Ra+Rb) is true, then the output of the comparator reaches the threshold level, and the output of Shmitt trigger is reversed from H to L, then the output voltage is equal to the supply voltage.

This output of PGH758A is generally connected, in parallel with a pullup resistor, to the interrupt input of the controlling microprocessor. The open drain feature allows wire-NORing with other interrupt inputs. The inactive state of INT is high impedance. When active, INT is driven to a low level output voltage. The state of INT is controlled and monitored by bits in the Mode Select and Status Registers. a digital-to-synchro/resolver converter using a sinusoidal refer- ence as an input; a digital-to-sin/cos DC converter using a DC reference; a polar-to-rectangular converter using a reference input proportional to the radius vector; a rotating cart- wheel sweep generator for PPI dis- plays using a sawtooth reference.

The PGH758A products described in this document are designed, developed and manufactured as contemplated for general use, including without limitation, ordinary industrial use, general office use, personal use, and household use, but are not designed, developed and manufactured as contemplated (1) for any use that includes fatal risks or dangers that, unless extremely high safety is secured, could have a serious effect to the public, and could lead directly to death, personal injury, severe physical damage or other loss (i.e., nuclear reaction control in nuclear facility, aircraft flight control, air traffic control, mass transport control, medical life support system, missile launch control in weapon system), or (2) for any use where chance of failure is intolerable (i.e., submersible repeater and artificial satellite).
