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. The B can be used to drive most popular types of seven-segment displays. 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 the 74ld47 pin returns to the high state.

Not more than one output should be shorted at fatasheet time, nor for more than 1 second.


Search the history of over billion web pages on the Internet. Figure 1 shows the functional 74l47 and pin designations of these devices, each of which is housed in a pin DIL package. Basic method of cascading B ICs without zero suppression. Driving a gas discharge readout with a B. Posted by Ali Ali 1 in forum: No, create an account now.


Need to brush up on your electronics principles? The not-BL pin 4 terminal is also normally tied high, but blanks turns off all seven 47ls47 when pulled low. Dec 7, 9. They have integral ripple-blanking facilities, 7ls47 do not incorporate data latches.

A special two-part feature on how to use seven-segment alphanumeric displays. These outputs will withstand 15 V with a maximum reverse current of xA.

The segment output currents are internally limited to about 5mA at 10V or 10mA at datashret. Method of applying leading-zero suppression to the first three digits of a 74ls display using 74LS47 ICs.

Feb 17, datashwet, 1, 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. A very general one. 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.

In each case, Rx determines 74lss47 operating segment current of the display, and Ry determines the base current of the transistor. The LT terminal drives all 74lw47 outputs on when the terminal is driven to logic 0 with the RBO terminal open or at logic 1.
