Prices for items, which are not held in our stock can be different from indicated ones. A current-limiting resistor Rx must be wired in series with each display segment and must have its value chosen to limit the segment current below 25mA.

The B can be used to drive most popular types of seven-segment displays. The display can be blanked at any time by driving the BL terminal to the logic-1 level. Notification will be sent ckos this e-mail address. Yes, please send me SOS electronic Newsletter by e-mail x per month. The B has four input control terminals, and three auxiliary output terminals.

The picture is only for illustration, please see the technical specification in product details. Support from development to manufacturing.

Share it with us. Driving a low-brightness fluorescent readout. Figure 4 shows the functional diagram and pin notations of the device, which can use any power source in the 5V to 15V range.

Figures 6, 7and 8 show how to modify the above circuit to drive LED common-anode displays, gas discharge displays, and low-brightness fluorescent displays, respectively.

The CO signal is a symmetrical square- wave at one-tenth of the CLK input frequency, and is useful in cascading B counters.

Fmos help us provide services. When the not-LATCH terminal is pulled low, the BCD input signals that are present at the moment of transition are latched into memory and fed in decoded form to the seven-segment outputs until cmps not-LATCH pin returns to the high state.

F ounded in In each case, Rx determines the operating segment current of the display, and Ry determines the base current of the transistor. Figure 1 shows the functional diagrams and pin designations of these devices, each of which is housed in a pin DIL package.

Using Seven-Segment Displays — Part 2

My dmos Current Price offers Price requests archive Send price request. Figure 3 shows how to connect the ripple-blanking terminals to give leading zero suppression on the first three digits of a four-digit display. Driving a gas discharge readout with a B. Figure 15 shows the basic circuit connections to be used cmso cascading stages. The segment output currents are internally limited to about 5mA at 10V or 10mA at 15V.

In practice, however, it is far better to use a B IC for this particular application.

74HC – BCD to 7-Seg LCD Latch Decoder Driver

The LT terminal drives all display outputs on when the terminal is driven to logic 0 with the RBO terminal open or at logic 1. Driving a fluorescent readout with a B.

Or do you have any interesting comments? Report a bug Compared products 0. Some of these devices have integral ripple-blanking facilities, others have built-in data latches, and a few even have built-in decade counter stages, etc. You only need to describe the error or your comment and provide your contact details. Driving a gas discharge readout.

The not-BL pin 4 terminal is also normally tied high, but blanks turns off all seven segments when pulled low. If you are already our customer but you do not know your login information request them.

Learning Electronics Need to brush up on your electronics principles? This procedure is repeated on all except the LSD, which does not require zero suppression.

If cascaded B ICs are required to give automatic leading-zero suppression, the basic Figure 17 circuit must be modified as shown in Figure 18 45433 provide ripple-blanking operation.
