The B can be used to drive most popular types of seven-segment displays.

We guarantee prices only for in-stock quantity. The IC does not incorporate a data latch and has no facility for ripple blanking. The not-BL pin 4 terminal is also normally cmod high, but blanks turns off all seven segments when pulled low. Note in the cases of Figures 6 and 7 that an NPN buffer transistor must be interposed between each output drive segment and the input segment of the display.

Figure 14 shows the functional diagram and pin 45543 of the B. Billing information Customer number. Driving a gas discharge readout. Way of using the B to drive a common-cathode or b common-anode seven-segment LED displays.

Need to brush up on your electronics cmo 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.

Would you like to change anything? Documents No documents to download. You only need to describe the error or your comment and provide your contact details. If you are already our customer but you do not know your login information request them. Support from development to manufacturing. Prices for mcos, which are not held in our stock can be different from indicated ones. In practice, however, it is far better to use a B IC for this particular application.

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 to provide cmoe operation. Basic method of cascading B ICs without zero suppression. Figure 4 shows the functional diagram and pin notations of the device, which can use any power source in the 5V to 15V range. F ounded in Driving a gas discharge readout with a B.

The 74LS47 has active-low outputs designed for driving a common-anode LED display via external current-limiting resistors Rxas shown in Figure 2. The picture is only for illustration, please see the technical specification in product details. Enabling the display can be connected directly to the outputs of the IC without the use of external current-limiting resistors.

Functional diagram and pin notations of the B decade counter with seven-segment display driver. The display can be blanked at any time by driving the BL terminal to the logic-1 level. Driving a low-brightness fluorescent readout. If trailing-zero suppression is required, the direction of ripple-blanking feedback must be reversed with the RBI terminal of the LSD grounded and its RBO terminal wired to the RBI terminal of the next least-significant stage, and so on.

You have items added to your shopping cart. The B is very easy to use, and has only three input control terminals; of these, the not-LT pin 3 pin is normally tied high, but turns on all seven segments of the display when pulled low.
