114 Price

114. Programmable memory EPROM structure and can be re-programming work?

In Electronic Infomation Category: 1 | on February 09,2012

Is the use of floating gate EPROM programmable memory production, its storage units to use more N-channel stacked-gate MOS (SIMOS), in addition to the control gate, there is no outer lead of a gate is floating gate. When there is no charge on the floating gate when the control voltage coupled to the control gate, MOS MOSFET; and 114 datasheet and when a negative charge on the floating gate when the substrate surface induced a positive charge, which makes the MOS turn-on voltage becomes higher tube If the control gate coupled to the same control voltage, MOS tube is still in a closed state, which SIMOS tube floating gate can be used whether the accumulation of negative charge to store binary data. data is written before the floating gate is not charged, to make the floating gate with a negative charge, mus...

114. How to determine high-frequency control and low frequency control?

In Electronic Infomation Category: 1 | on November 24,2011

Multimeter can be used to quickly determine, determine the method: first transistor emitter with a multimeter to measure the resistance of the reverse, if it is measured PNP-tube, the negative terminated Multimeter base, emitter is terminated; If the tube is a measure of NPN type, the meter base is terminated, a negative termination emitter. Then use a multimeter R 1kQ block measurement, the multimeter dial indication at this time should be great resistance, generally less than full-scale value of 1 / 10. Multimeter and 114 datasheet and then converted to R 10 kfl block, if a large resistance change the dial indication, more than full-scale value of 1 / 3, then the tube is high-frequency control; the other hand, if the multimeter switch to R 10 kfl after block , hands indicated little change in resista...

114 points to the types of digital integrated circuits? What is included in each series of species?

In Electronic Infomation Category: 1 | on September 20,2011

Bipolar digital integrated circuits are integrated circuits (such as TTL, ECL) and 114 datasheet and unipolar integrated circuits (eg CMOS) two categories, each category also contains a series of different varieties. TTL digital integrated circuits: This type of integrated circuit input stage and 114 price and output stage within the transistor structure are, are bipolar digital integrated circuits. The main series: (1) 74 series: This is an early product, is still used, but is gradually being phased out. (2) 74H Series: This is an improved 74 series, a high-speed TTL products. The NAND gate, the average transit time of 10ns or so, but the static power consumption of a larger circuit, the current use of the product less and 114 suppliers and less, is gradually phased out, (3) 74S series: This is a TTL high-speed Schottky-type seri...
