This allows the tuner designer several design possibilities: Be- cause of limitations on package power dissipation, simultaneous operation of all drivers at maximum rated current can only be accomplished with a reduc- tion of duty cycle. Functionally, the eight-bit device is the equivalent of an octal latch ratasheet an octal NPN Dar- lington array.

Each input has a Zener diode and resistor in series to limit the input current datasgeet a safe value in that application. The tuning indicator circuit reduces the I-F gain by about 2 dB. A — 2X or -3X device can also be used by parallel- ing the equivalent tuner load with a fixed resistor to present an 2 load or a 2 load.

Input test conditions are listed in Table IV. The maximum resistor value is deter- mined from: The amplitude modulation rejection is determined by: Total component count is approximately 30 pieces, and the board layout is straightforward and uses single-sided board.

All decoupling capacitors should be of the ceramic type with minimum inductance at the operating frequency. Internal voltage, current, and temperature shut-down circuitry protect these devices under the most severe operating conditions.

All of this is the result of customer and sales inquiries along with an under- standing of the industry needs for improved power interface ICs. It is designed for use with vacuum fluorescent displays, but has been put to many datasheeet uses, including control of thermal print heads.

Phase shift network is aligned by applying F-M signal through de- coupling network to pin 4 V 4 – 5 mV rm s. The protective value of R 4 and R 5 must be noted; a junction failure in Q t has the two resistors as a current limiter to the MOS or TTL output and will minimize the likelihood of destroying the low level logic outputs. Subsequent devices have included gain-control stages, output drivers, datasheft voltage regulators. Reliability satasheet a product of design and process control.

To insure proper opera- tion, resistor R should be used as shown in the typical application. Compounding this problem would be the effect that a high drive current requirement would have on the logic output voltage since that is normally specified at only m A.

Since the I-F amplifier is an independent element, various combinations of filters before and after the amplifier are possible. Common mode signals are rejected through the use of balanced current-mirror outputs.

All eight of these devices include integral transient suppression diodes for use with inductive loads. Problems datasheeg leading zero blanking, low temperature, low ambient light, etc. The higher voltage displays gas-discharge, vacuum fluorescent, a-c plasma, and d-c electroluminescent may share some circuits if appropriately planned and designedparticu- larly in the area of matrix displays.

For the UDSH inver- under any ambient temperature. All input connections are on one side of the packages, output pins on the other, to simplify printed wiring board layout. Type UDNW, for higher power requirements, is in a pin single in-line power tab package. The circuit combines sink and source drivers with diode protection, gain and level shifting systems, and a voltage regulator for single-supply operation.

These electrical requirements are well within the capability of many gas discharge digit drivers. If a positive supply dtaasheet used, relatively complex d-c level shifting would be required in the anode side. See following part number description. The minimal component lm13911n and straightforward printed wiring board layout offer benefits in cost reduction, simplicity of board layout, and savings in space.

In lm3191n cases the output is switched ON by an active high input level.

A d-c path of less than q must be provided between pins 2 and The l N 0FF current limit guarantees against partial turn-on of the output. Contact the local sales office or factory for additional information. The lm13391n phase detection output. If a high-impedance power supply is used volt- age dropping resistordecouple pin 11 for the lowest audio frequency. Transient Suppression All five power outputs are diode protected against inductive transients.

Interference and datashedt are rejected. The output transistors are capable of sinking mA and will sustain at least 50 V in the off state. Datasheet pagepro en 4 Documents. When ddatasheet with standard TTL or low-speed TTL logic, both devices may require employment of input pull-up resistors to insure a proper input logic high.
