DESCRIPTION
The M54/74HC4511 is a high speed CMOS BCDTO-7 SEGMENT LATCH/DECODER/DRIVER fabricated with silicon gate C2MOS technology. It
enables high speed latch and decode operation with
identical pin connection and function to standard
CMOS 4511B.
The segment output driver, which is CMOS fabri2
cated in silicon gate C MOS technology, 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.

(*) 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 operting current can be obtained by the following equation. ICC(opr) = CPD •VCC •fIN + ICC/2 (per FLIP/FLOP)
