The combination of coupling capacitor C 2 and daatasheet amplifier output pin 9 was chosen for optimum quieting.
Printed wiring board real estate is increasingly dictating smaller size. Cost, chip size and package power dissipation dataeheet restrict this circuitry lm3191n to versatile, simple buffers. False trig- gers on adjacent channels and strong mistuned sig- nals are eliminated by its off-tune muting, which exhibits a greater voltage change than that of com- monly used signal-level muting.
Typical applications include driving peripheral loads such as incandescent lamps, light-emitting diodes, memories, and heaters with a load current of up to a mA peak value. External component choice for the power am- plifier involves only two capacitors; one for the speaker coupling and one for the feedback and ripple by-passing. Although typically less than 1 per cent of a lot will be rejected, user confidence in lot integrity is greatly improved.
Type UDNB is in a pin datazheet in-line package with heat-sink contact tabs. For display applications, these reliability improvements are of greatest concern in high-voltage devices. Applications The Series and may be used in a variety of low-voltage to high- voltage interfacing applications such as are found in MOS calculators, digital clocks, etc.
The minimum recommended scan frequency is Hz per character a clock frequency of 2 kHz for a character display. The unit may have data inputs and a strobe bus see Figure 6. A hermetically sealed version of Type UDNA, with reduced package power dissipation ratings, is available on special order.

Some increase in standoff voltage may be afforded by the uses of cascaded output transistors or process improvements, thus reducing the need to sacrifice logic density. No other biasing provisions are datasheef.
The output transistors are capable of sinking mA and will sustain at least 50 V in the OFF state. Other inputs at 0.
Minimum data active time after strobe disabled data hold time ns C. Through a collaborative effort begun late in between Sprague Electric and Burroughs Corp. The ULNA audio amplifier stage has other input considerations to be taken into account for best results. High-Temperature Bake This is a process designed to stabilize electrical drift and to accelerate chemical degradation such as surface contamina- tion.
Datasheet pagepro en 4 Documents. The UDNZ may be used in pairs full- bridge for d-c stepper motor or brushless a-c motor drive applications. The use of TTL in such a manner is not recommend- ed due to the higher currents and resultant high level of package power dissipation. Type ULNA is designed to work within a range of supply voltages from 4. Smaller module or display subassemblies. In the A-M mode of operation.
The high-gain, high-impedance operational amplifier configuration allows many specialized input, output, and feedback arrangements. Quality is verified by testing. In the A-M mode, the detector is operated as a balanced peak detector.
In applications which allow the selection of the power supply voltage it is therefore recommended that a datashdet load impedance be utilized in applications up to 0. Plasma displays are well-suited to custom panels particularly those with various sizes of characters and with improvements in IC break- down voltages some further simplification of inter- face should evolve.

The higher impedance load will also fur- nish a significant reduction in harmonic distortion and improvement in overall repeatability in power output capacity. The UDS- H driver uses a grounded-base input stage for non-inverting operation while the UDSH driver uses a common-emitter input stage for inverting op- eration. The lamp test feature can of level of 3. A d-c path of less than q must be provided between pins 2 and Output Current Ireg 13 2.
Outside the l-F filter passband, pin 12 voltage will be reduced as a function of system gain. The ten bipolar outputs are used as segment or digit drivers in vacuum fluorescent displays.
Higher package power dissipation may be obtained at lower operating temperatures. The bipolar outputs are suitable for use with relays, solenoids, stepping motors, LED or incandescent displays, and other high-power loads.
Large-volume use of DI circuits will be restrained until these problems particularly alternate sources can be overcome. Outputs may be paral- leled for higher load current capability. There are three selections for each mode of operation and nine possible combinations. All semiconductor wafer fabrication is done in the Worcester plant, as are all services integral to its support.
The relay driver types of Sprague IC drivers and other similar transient-protected ICs are somewhat more useful than the so-called general purpose types, since the diode common terminal may be switched for a system lamp test.
