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 not-LATCH pin returns to the high state. The B can be used to drive most popular types of seven-segment displays.

CMOS – CMOS – BCD to 7-Segments Decoder/Latch/Driver

If mcos 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 ripple-blanking operation. Would you like to change anything? Figure 14 shows the functional diagram and pin notations of the B.


Basic method of cascading B ICs without zero suppression.

The prices are exl. The opening episode of this special feature explained the basic operating and usage principles of seven-segment alphanumeric displays. Driving a gas discharge readout. Enabling the display can be connected directly to the outputs of the IC without the use of external current-limiting resistors. You only need to describe the error or your comment and provide your contact details.

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.


Need 45443 brush up on your electronics principles? Basic way of using the B to drive a seven-segment common-cathode LED display. Search only SOS order numbers. The not-BL pin 4 terminal is also normally tied high, but blanks turns off all seven segments when pulled low.
