DESCRIPTION The M74HC4511 is an high speed CMOS BCD-TO-7 SEGMENT LATCH/DECODER/ DRIVER fabricated with silicon gate C2MOS technology. The segment output driver has large IOH capability which enables common cathode leds to be directly driven. When lamp test (LT) is taken "L", all segment outputs will go to "H", and when blanking (BI) is taken "L" and LT is taken "H" all segment outputs will go to "L".
These functions operate regardless of other inputs and are used to test the display. Input BI is used to pulse-modulate the brightness of the display. When an error input code (over 10) is applied to the BCD input, all segment outputs will go "L" (turn off). All inputs are equipped with protection circuits against static discharge and transient excess voltage.

CIN CPD
Input Capacitance Power Dissipation Capacitance (note 1)
1) CPD is defined as the value of the IC's internal equivalent capacitance which is calculated from the operating current consumption without load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC
